1 OVERVIEW

The HMC6 protection and power management controller is a standard power management system for marine applications. The system carries out generator control, supervision and protection functions. The power management functions are calculated by all diesel generator units, making the system a true multi-master system. One of the diesel generator units is internally defined as the "command unit". This unit is the one where start priority and other power management-related functions are calculated.

The system can handle up to 16 diesel generators to automatic synchronization and load sharing.

Should the command unit fail, the power management calculations will automatically be transferred to the next available unit. The internal communication between the units is carried out via internal CANbus. This CANbus is intended for internal communication use only and cannot be connected to other external CANbus systems.



2 PERFORMANCE AND CHARACTERISTICS



Dynamic synchronizing: detect the phase angle difference, voltage difference and frequency difference automatically to perform synchronization as soon as possible.



Load sharing: Schedule the start and stop of genset and share load equally automatically.



Heavy consumer control: Start the additional genset automatically if the power is not enough when the function is active.



NEL trip: Trip some non-essential load if over power condition occurs.



Light load: The genset is still running if the load has fallen below the shutdown set value when the function is active.



Suitable for 3-phase 4-wire, 3-phase 3-wire, single phase 2-wire, and 2-phase 3-wire systems with frequency 50/60Hz;



Selectable start mode: Cyclic start; Linear start; Duty Time start;



480x272 LCD with backlight, multilingual interface (including English, Chinese or other languages) which can be chosen at the site, making commissioning convenient for factory personnel;



Parameter setting: parameters can be modified and stored in internal FLASH memory and cannot be lost even in case of power outage; most of them can be adjusted using front panel of the controller and all of them can be modified using PC via USB or RS485 ports;



Event Log：Maximum 99 pieces of trip alarms, trip and stop alarms can be saved in chronological sequence in internal memory, which means that they will not be lost in case of power off.

6. SYSTEM MODE DESCRIPTION

6.1 SYSTEM MODE

6.1.1 MANUAL MODE

When Manual mode signal is active, the system will work through manual mode. In this mode,

HMC6 controller can only monitor data and alarm information but cannot control switch or engine.

In addition, GOV and AVR do not work but the manual governor, relay governor, manual VOLT IN and manual VOLT OUT do work in this mode.

6.1.2 SEMI-AUTO MODE

Semi-auto mode is activated by pressing key; Semi-auto means that the unit will not initiate any sequences automatically, as is the case with the auto mode. It will only initiate sequences, if external signals are given.

An external signal may be given in three ways:

1. Push-buttons on the display are used

2. Digital inputs are used

3. Modbus commands are used

All available diesel generator units can be started/stopped/synchronized/closed/opened/unloaded upon push-button commands on the front panels for each generator.

The system monitors that the generators are not overloaded. Should that be the case, the Non

Essential Load (NEL) trip will activate to maintain power supply to the main busbar.

If a heavy consumer is requested, the system calculates the power needed. If the available power is insufficient, the heavy consumer connection will not be allowed.

Semi-auto Start：

1 Start command will be initiated by HMC6 after pressing into “Start Output Delay” while the start relay will activate.

button. The system enters

2 When Start Output Delay is over, Start Wait Delay will be initiated. Fail to Start alarm will be initiated if the onload requirement has Not been achieved after the Start Wait Delay has expired. The alarm type of Fail to Start is block which means users can restart the generator only when the alarm is acknowledged.

3 When Start Wait Delay is over, Load Stability Delay will be initiated. F/V Fault alarm will be initiated if the onload requirement has Not been achieved after the Load Stability Delay has expired. The alarm type of F/V Fault is block which means users can restart the generator only


HMC6 PROTECTION AND POWER MANAGEMENT CONTROLLER when the alarm is acknowledged.

However, it enters into “Normal Running” status if the onload requirement has been achieved.

4 If the switch is not closed during the normal running status and the voltage/frequency has not satisfy the onload requirement suddenly, Transient Fault Delay will be initiated. F/V Fault alarm will be initiated if the onload requirement has Not been achieved after the Transient

Fault Delay has expired. The alarm type of F/V Fault is block which means users can restart the generator only when the alarm is acknowledged.

5 If the onload requirement has been achieved (Generator normal light will illuminate), the genset will close and synchronize automatically after pressing the button.

6 In case of multi-set operation, the genset will share load automatically.

7 If there is trip alarm occurs, then the system will open switch and the alarm information will be displayed on the LCD.

Semi-auto Stop：

1. Press stop button , in case of multi-set operation, first of all, the system will transfer load.

2. Open relay activate only when the load transfer is finished.

3. After the switch is opened, the system enters into “Stop Output Delay” while the stop relay will activate.

4. The system enters into standby status after the Stop Output Delay has expired.

6.1.3 AUTO MODE

Auto mode is activated by pressing key;

All available diesel generator units are controlled by the power management system and are started and stopped according to the start priority and the actual busbar load. Should a running generator develop an alarm, the system will start the next generator in line and synchronise its breaker before taking the failing generator out of service. At the same time, the system monitors that the generators are not overloaded. Should that be the case, the Non Essential Load (NEL) trip will activate to maintain power supply to the main busbar.

If a heavy consumer is requested, the system calculates the power needed and starts an additional generator if needed before allowing the heavy consumer to be connected.

Auto Start Rules

1. If the system detects that there is no voltage signal on busbar, then the available diesel generator units are started according to the start priority.



2. Should the generator units are started successfully, the system will start the next generator in line if the power is insufficient.

3. Should the generator units are in normal running, if a heavy consumer is requested, the system calculates the power needed and starts an additional generator if needed before allowing the heavy consumer to be connected; then the system will output acknowledged signal if the request is satisfied.

Auto Start

1

Generator enters into “start delay” as soon as “Auto Start” is active.

2 After the Start Delay has expired, the system enters into Start Output Delay while the start relay will activate.

3 When start delay is over, Start Wait Delay will be initiated. Fail to Start alarm will be initiated if the onload requirement has Not been achieved after the Start Wait Delay has expired. The alarm type of Fail to Start is block which means users can restart the generator only when the alarm is acknowledged.

4 When Start Wait Delay is over, Load Stability Delay will be initiated. F/V Fault alarm will be initiated if the onload requirement has Not been achieved after the Load Stability Delay has expired. The alarm type of F/V Fault is block which means users can restart the generator only when the alarm is acknowledged. However, it enters into “Normal Running” status if the onload requirement has been achieved.

5 If the switch is not closed during the normal running status and the voltage/frequency has not satisfy the onload requirement suddenly, Transient Fault Delay will be initiated. F/V

Fault alarm will be initiated if the onload requirement has Not been achieved after the

Transient Fault Delay has expired. The alarm type of F/V Fault is block which means users can restart the generator only when the alarm is acknowledged.

6 If the onload requirement has been achieved (Generator normal light will illuminate), the genset will close and synchronize automatically after pressing the button.

7 In case of multi-set operation, the genset will share load automatically.

8 If there is trip alarm occurs, then the system will open switch and the alarm information will be displayed on the LCD.


Auto Stop Rules


1. In multiple gensets running system, if the system detects that the load power has fallen below the stop power, the controller will transfer load according to the start priority.

2. Should the load is transferred completely, only then open relay activate.

3. Stop command will be initiated.

Auto Stop

1. Press stop button , in case of multi-set operation, first of all, the system will transfer load.

2. Open relay activate only when the load transfer is finished.

3.

After the switch is opened, the system enters into “Stop Output Delay” while the stop relay will activate.

4. The system enters into standby status after the Stop Output Delay has expired.

8.2.5 MSC LINK PORT

Data sharing and data communication functions among HMC6 controllers are implemented via

MSC LINK (CANBUS port). Detailed connection way is as following:



9. POWER MANAGEMENT AND WORKFLOW CHART

There are two kinds of power management mode: Equal load sharing and Base load.

9.1 EQUAL LOAD SHARING

Equal load sharing is active both in auto mode and semi-auto mode. In both cases, load sharing is carried out via the internal CANbus line(s).

There are two kinds of equal load sharing ways: kW load sharing and kVar load sharing.

1、 kW load sharing：The equal load sharing of active power of each unit on busbar can be adjusted via GOV.

2、 kVar load sharing：The equal load sharing of reactive power of each unit on busbar can be adjusted via AVR.

9.2 FIXED POWER

Each unit can be selected as running with fixed power. This can be done from the panel parameters or via a binary input.

The unit selected for base load operation will automatically be set in SEMI-AUTO. Only one generator per independent busbar can run with base load.

Active power output value and reactive power output value can be set, in addition, power factor also can be set.

When the generator breaker is closed, the generator power will be increased to the fixed power setpoint.

9.3 SYNCHRONISING

9.3.1 DYNAMIC SYNCHRONIZING

During dynamic synchronizing, the unit which is going to synchronized is running at a different speed to busbar generator, and the speed difference between them is named as slip frequency.

Generally, the synchronizing unit is running at a positive slip frequency which means it is relatively faster than busbar generator, so that the generator reverse power is avoided after synchronizing.

The aim of synchronization is reduce the phase angle between two systems (refer to 3-phase systems of generator and busbar).

Voltage difference, frequency difference and angle difference should be set during dynamic synchronizing. The breaker is going to closed if all of them meet the requirement.



9.3.2 STATIC SYNCHRONIZING

During static synchronizing, the unit which is going to synchronized is running at a near-unanimous speed to busbar generator, so that the phase angle between generator and busbar are matched exactly.

When synchronizing is started, the synchronizing controller is activated and the generator frequency is controlled towards the busbar frequency. The phase controller takes over when the frequency deviation is so small that the phase angle can be controlled.

NOTE：We discourage you from using static synchronizing when adjust it using relay output because it respond slowly.



9.4 HEAVY CONSUMERS

Each HMC6 controller is able to handle three Heavy Consumers (HC).

When a heavy consumer is requested, the function for conditional connection of heavy consumers reserves the programmed HC requested value on the busbar, until sufficient predicted available power is present at the busbar.

The picture above shows：

1、 HC1 request power is 300kW; HC1 rated power is 150kW;

2、 The busbar reserved 300kW for HC1;

3、 HC ACK Delay will be initiated if there is enough redundancy power on busbar.

4、 The controller will output acknowledgement signal after the HC ACK Delay. After the acknowledgement has output, HC1 request power is equal to HC1 rated power, then the busbar only reserved the HC1 rated power.

5、 If the HC feedback is active, the busbar reserved 0% power for HC1.

6、 If the HC feedback is deactivated while the HC request is active, the busbar only reserved the HC1 rated power.

7、 If the HC feedback and the HC request both are deactivated, then the busbar reserved

0% power for HC1.



9.4.1 HEAVY CONSUMER REQUESTS

Heavy load equipment should send a heavy consumer request before starting up. Only binary input can be handled by HMC6 and the request value must be fixed load value. Each heavy consumer request can set a corresponding power value.

9.4.2 HEAVY CONSUMER ANSWER

If a heavy consumer is requested, the system calculates the power needed and starts an additional generator if needed before allowing the heavy consumer to be connected. If the request is satisfied, acknowledged signal will be initiated and the controller does not reserve any power.

Example：

1：There is 60kW redundancy on busbar which is composed by two parallel running generators, then the heavy consumer request 1 is active (request power is 70kW).

2：An additional 100kW generator should be started.

3：There is 160kW redundancy on busbar after the additional 100kW generator is started, then the acknowledged signal will be initiated.

9.4.3 HEAVY CONSUMER FEEDBACK

It is a binary input signal, heavy consumer feedback signal will be initiated if the request is satisfied.

As the example above illustrates：

1：After the answer is active, the real power of the load is 30kW, there is 130kW redundancy on busbar, stop condition is satisfied.

2：The additional 100kW generator will be stopped.

9.4 TRIP OF NON ESSENTIAL LOAD (NEL)

The trip of Non Essential Load (NEL) groups is carried out in order to protect the busbar. Each

HMC6 controller is able to handle three non essential load trip (NEL). Trip priority is: NEL1>

NEL2> NEL3. If the active power has exceed the set value, the corresponding NEL will trip after the trip delay, and the warning alarm will be initiated. NEL trip can be reuse after reset only.

After the Fail to Stop delay, the genset is stopped successfully if the voltage and frequency are 0; while the warning alarm will be initiated if they are not 0.

Time from start signal is active to onload requirement is satisfied.

If the requirement is continue satisfied in onload stable delay, synchronization is beginning.

If the requirement doesn’t be satisfied but delay time is up, then the warning alarm will be initiated.

After the onload stable delay, If the voltage and frequency requirements are not satisfied after the transient fault delay has expired, then the Freq/Volt Fault alarm will be initiated.

If the busbar redundancy power is meet the HC request, then the HC answer output after the HC answer delay.

10 COMMISSIONING

STEP 1. SINGLE UNIT DEBUGGING

1) Check the parameter configuration of the controller;

2) Check the gen-set connections and MSC CAN connection lines between the units. (E.g. if 3 generators are correctly connected, SYNC screen will display Module Number: 3).

3) Start the genset in semi-auto mode, check if engine and generator data is normal;

4) Start the genset in semi-auto mode, check if switch opens and closes normally;

5) Start the genset in semi-auto mode, after closing the breaker, check if generator frequency can be adjusted to the rated frequency (e.g. set the rated frequency as 52Hz/48Hz);

6) Start the genset in semi-auto mode, after closing the breaker, check if generator voltage can be adjusted to the rated voltage (e.g. set the rated voltage as 240V/220V)

7) Start the genset in semi-auto mode, after closing the breaker, check if power factor, active power and reactive power are normal; if negative value occurs, check generator voltage and current phase sequence, current transformer incoming line direction, current transformer secondary current dotted terminal;

STEP 2: SEMI-AUTO PARALLEL OPERATION OFF-LOAD

1) Semi-Auto close parallel sets, check that the units synchronization is balanced and breaker close impulse current is not too high;

2) During parallel operation off load, check that there is no high circumfluence on HMC6 current screen;

3) During parallel operation off load, check if the output of active and reactive power is equal to zero; if it is not, then check if there is power oscillation; if there is, adjust the gain and stability values of engine, or adjust engine GOV or generator AVR gain and stability potentiometer to avoid active and reactive power oscillation; output close to 0.

STEP 3: SEMI-AUTO PARALLEL OPERATION ON-LOAD

1) Semi-Auto close parallel sets, perform on-load test and check if active and reactive power is evenly distributed between all the gensets

2) Semi-Auto close parallel sets, perform ramp on-load test to see if there is high overshoot or power oscillation during this period; if there is, regulate Load Ramp via PC software.

3) Semi-Auto close parallel sets, perform ramp off-load test to see if gen-set breaker opens after reaching minimum set value (%);



4) Semi-Auto close parallel sets, perform impact load test and damp load test to check if there is power oscillation

STEP 4: AUTOMATIC PARALLEL OPERATION

When the controller is in auto status, if there is no power on busbar, it will carry out automatic parallel, start and stop operation.

1) Start the genset which has the highest priority or shortest running time according to the start mode.

2) The genset which has the second highest priority or second shortest running time will be started if the load has exceeded the set value or the HC request has exceeded the set value.

3) After the genset has started up, synchronization, parallel and share load process will beginning.

4) The genset will be stopped according to the preset sequence if the load has fallen below the set value (light load input deactivates.)

HMC6 Single Unit Typical Application Diagram



11 INSTALLATION

Controller is panel builtin design; it is fixed by clips when installed. The controller’s overall dimensions and cutout dimensions for panel, please refers to as following,

1) Battery Voltage Input

NOTE:

HMC6 controller can suit for widely range of battery voltage (8~35) VDC. The wire’s diameter must be over 1.5mm

2 and which is connected to B+ and B- of controller power.

2) FREQ IN, VOLT IN

NOTE: FREQ IN and VOLT IN are work only when external adjust is active. Range:

-10V~10V.

3) Output And Expand Relays

NOTE: All outputs of controller are voltage free output (rated capacity is 8A). If need to expand the relays, please add freewheel diode to both ends of expand relay’s coils (when coils of relay has DC current) or, increase resistance-capacitance return circuit (when coils of relay has AC current), in order to prevent disturbance to controller or others equipment.

4) AC Input

Current input of controller must be connected to outside current transformer. And the current transformer’s secondary side current must be 5A. At the same time, the phases of current transformer and input voltage must correct. Otherwise, the current of collecting and active power maybe not correct.

NOTE: Dotted terminal must be connected to negative pole of battery.

WARNING!

When there is load current, transformer’s secondary side prohibit open circuit.



5) Withstand Voltage Test

CAUTION! When controller had been installed in control panel, if need the high voltage test, please disconnect controller’s all terminal connections, in order to prevent high voltage into controller and damage it.
