Using
Control system (CU) is designed to control motor-generator sets with phasing
generators to the distribution network, supports different modes of cooperation with
the network contains network protection, generator and motor protections.
With user-defined functions (gates, flip-flops, analog members, PID controllers,
control blocks for three-way valves, etc.) is possible the basic firmware easily
extended with additional functionality (see documentation "ManagerAP a mapping
function") ..
For technical specifications of the device (HW description, count and types of inputs
and outputs, communication interfaces e.t.c.) see documentation “Specification
UniGEN AP HW VN”.
Using RS-232 interface is possible to connect device to PC, control, visualize and
configure it using program “ManagerAP”. See documentation “Manager AP user
manual”.
For connection CU to PC use 3-wire cross-over cable (2-3, 3-2, 5-5, “nullmodem”)
with CANNON 9F.

Start of the aggregate in manual or semi-automatic mode –
activating the demand for aggregate run. Is there a start block, the
start is taking place immediately after the reason for blocking has
gone off.
In case there is a semi-automatic mode set, CU will either pass on
to parallel operation (net deion is shows on-state) or pass on into
operation under load (net deion shows off-state).
If there is a manual mode actual, CU goes over immediately after
start only to nominal speed operation mode.
Keystroke during the relieving phase (i.e. the demand for
successive unloading) causes the return to the parallel (island)
operation.
Initiation of shut-down and semi-automatic mode transition
(provided this was actual in automatic mode). It activates releasing
and after a time-out expiry desynchronizes (in parallel mode) or
disengages generator contactor (in solitary mode) and after cooling
evokes Stop.
Keystroke during the relieving phase results in immediate contactor
disengaging and cooling run transition.
Keystroke during the cooling run results in immediate stopping of
cooling run and unit halt.

Operating of net deion. Controlling of net deion is possible in
manual mode only, and in only a few modes under net cooperation
(E, P+I and P+E). In cooperation modes P and I is this key blocked,
panel LED indicator of the net deion in P-mode is lighting
constantly, in I-mode is not lighting constantly.
In cooperation mode P+I can be selected by means of key whether
the generator will be working in solitary or parallel operation (unless
the deion-controlling is blocked through the parameter “MCBCrtlPI”
from the CU-key board), automatic mode does not actuate the deion
status.
In E and P+E cooperation mode as well as in CU-automatic mode is
the output governed according to CU-algorithm.
Touch of button activates the deion-grids
(irrespective the generator operation status).
Touch of button deactivates the deion-net
(irrespective the generator operation status).
Touch of button activates backwards synchronizing
towards the net and subsequently parallel operation
with the net. The retouch during the backwards
synchronizing towards the net will defeat the
backwards synchronizing. Overrun of warning or
emergency limits of some of the net or generator
parameters (U, f, phase) will block deion contact
making which can lead to malfunction of the “not in
time synchronized”.
Touch of button deactivates the deion-net and
causes generator transition from parallel to solitary
operation (operation on-load).
Operating of generator deion. It is possible to govern the deion in
manual mode only (it is governed automatically according to CUalgorithm in the automatic mode).
If the generator is running with nominal speed the
touch of button causes attachment of load and
passing on into operating on-load
If the generator is running with nominal speed the
touch of button activates synchronization toward the
net (provided emergency limits of net parameters are
not exceeded). The re-touch during the
synchronizing will annul the synchronizing. Overrun
of warning or emergency limits of some of the net or
generator parameters (U, f, phase) will block contact
making for deion which can lead to malfunction of
the “not in time synchronized”.
Touch of button will disconnect the load and
courses transition from running on-load into
unloaded run at nominal speed.
Touch of button causes generator desynchronizing
and transition to parallel operation with unloaded run
at nominal speed.

synchronizing stage automatically. From CU key-board it is possible
to operate manually GCB and MCB. Provided “COPY” mode is
selected at the same time, the unit can be started irrespective the
value of desired performance; if the desired level is low the CHP is
running with the min. power (in parallel).
Semi-automatic Mode; Start and Stop of the unit occurs using the
keys START/STOP, nevertheless further it is running fully
automatic, i.e. in the same way as in automatic mode. GCB and
MCB operation from the CU key-board is locked.. Provided the
“COPY” mode is selected at the same time and the net deion is
switched ON the starting and stopping of the unit occurs in
accordance with the power desired.

Requested power can be fixed internal parameter (XXXkW mode) or external
requirement for entering into a logic control system via analog input "External power
request (Copy)" (COPY mode). Input "External power request (copy)" can be
mapped e.g.to network active power (in this case will follow the power value
measured on the network) to the physical current input 20 mA, at the output of user
functions etc.
If during operation no active power limitation value Preg will have the same value as
