Enterprise Energy Measurement
and Monitoring
In order to provide output power from solar photovoltaic (PV) installations and wind turbine systems
over a longer time period than conditions allow (due to darkness or insufficient wind speed), it is
necessary to store the generated energy for later use as demand requires. For storing the generated
energy in banks of Li-Ion cells, advanced technology solutions from Analog Devices enable safe and
efficient systems operation over time and temperature.
The diagram below demonstrates an outline system diagram for a solar PV system where storage
components are identical to those in a wind turbine system. Li-Ion cells are generally grouped in
modules or packs containing between six to 12 cells, then bolted together in a series (two battery
strings shown below) to produce the desired overall stack voltage.

Assigning dedicated monitoring components to each string eases individual string removal and allows
tighter control over the Li-Ion cells. Highly specialized cell monitor products such as the AD7280 and
the AD8280 provide full monitoring and backup capabilities for each Li-Ion cell in the string while
the individual string current can be monitored by the special purpose ADuC703x. The ADuC703x also
communicates with its associated series-connected string of Li-Ion cell monitors, running cell balancing
algorithms and communicating with the master Blackfin® DSP controller (ADSP-BF50x). The processor
communicates with the various system blocks via iCoupler® devices (ADuM140x) to allow the entire
front-end system to float and to electrically isolate the back end from high voltages for safety reasons.

In the above diagram, common current and voltage measurements are taken in at least three
locations to help with the system management; I1 and V1 help with the MPPT algorithm; I2 and V2
help with the V/I charging a circuit; I3 and V3 help with the inverter operation. These three voltages
are high voltages and can be measured via resistive dividers into the voltage channels of the
ADuC703x. The I1, I2, and I3 current measurements can be made with current monitoring products
such as the AD8212 or AD7400.
Blackfin Processors with Integrated ADCs Break Price/Performance
Barriers for Solar and Wind Applications
The global movement to drive greater energy efficiency across electrical and industrial infrastructure requires sophisticated
technology for intelligent power management. Leveraging advanced power control techniques for applications spanning industrial
control and automation, renewable energy generation, and smart grid energy distribution, system designers can achieve significant
efficiency gains that yield greater energy conservation, lower pollution emissions, and tremendous economic savings.
Blackfin ADSP-BF50x processors deliver up to 400 MHz of processing performance at a price point where 150 MHz to 200 MHz clock
speeds have been the norm. In addition, optional integrated analog-to-digital converters (ADCs) and flash memory are available.
This performance profile equips designers to achieve greater system functionality and precision through the use of more sophisticated
algorithms and enables a number of system-level design objectives, including real-time processing of more data, reduced latency,
consolidation of processing tasks to a single processor, and greater flexibility to optimize system interface and control capabilities.
Blackfin ADSP-BF50x processors are ideally suited to execute the complex algorithms that enable inverters to convert variable
dc output into “clean” current and regulate power flow into the commercial electrical grid and/or local electrical networks fed by
residential and municipal PV cell arrays and wind turbines. With the signal processing performance to ensure ultraefficient energy
extraction and transmission, advanced power switching control functionality, and support for anti-islanding and maximum power point
tracker (MPPT) capabilities, Blackfin ADSP-BF50x processors are optimized for renewable energy and smart grid infrastructure.
The ADSP-BF50x family includes the ADSP-BF504 starting at $4.50, the ADSP-BF504F with integrated flash memory starting at
$6.50, and the ADSP-BF506F with integrated flash memory and

Next Generation Wind Turbines Utilize Precision ADI Components
to Maximize Energy Extraction and Optimize System Controls
Northern Power Systems’ Northwind™ 100 delivers 100 kilowatts of rated power for community wind applications such as schools/
universities, businesses, farms, and municipalities. ADI’s expertise in next generation energy infrastructure assures that companies like
Northern Power Systems are equipped with advanced components across the entire signal chain to enhance the value, performance,
and innovation of their system designs.
The power flow of the Northwind 100 generator is regulated by the power converter to compensate for variable wind speeds, which
helps to maximize energy extraction. This capability ultimately enables a Northwind 100 wind turbine to provide a steady flow of clean
power to a local grid, simplifying grid interconnect infrastructure and maintaining grid stability. Eliminating the need for a gearbox
transmission dramatically reduces lifecycle maintenance and increases system reliability.
At the heart of this system is ADI’s 32-bit floating-point SHARC® ADSP-21363 digital signal processor, which hosts real-time,
closed-loop control algorithms to efficiently control the Northwind 100 generator and power converter subsystems, based in part on
incoming data provided by the AD7656 16-bit analog-to-digital converter (ADC) embedded in the data acquisition hardware. Vibration
monitoring uses ADI’s dual-axis iMEMS® ADXL203 accelerometer subassembly part affixed to the turbine’s nacelle.

Digital Isolation Technology Enables Cost-Effective, Reliable Solutions
Isolation is an important component of energy metering systems and is used at different parts of the system depending on the specific
system topology. For example, if shunt resistors are used for current measurement, isolation is often used at the output of the ADC
or metrology IC to protect the microcontroller and communications system from the mains voltage. Other areas where isolation is
commonly used include external interfaces (such as RS-485), communications interfaces, and human interfaces.
Most modern utility meters include complex communications boards for interfacing to automatic meter reading (AMR) or advanced
meter infrastructure (AMI) systems. The two most common communications methods are wireless and power-line communication
(PLC). Similar methods are used for enterprise or nonutility metering applications, in addition to USB (ADuM4160) and network
connections. Isolation is used to protect both the communications and metrology modules in the event that a large voltage differential
develops between the modules.
Analog Devices offers a comprehensive portfolio of isolation ICs, both iCoupler digital isolators and isoPower isolators that include
power isolation. Integrated power isolation allows the designer to reduce the number of components required for a design or to
implement isolated power domains in challenging areas.
Many meters utilize RS-485 connections for calibration, debugging, and/or local control/reading. ADI also supports a comprehensive
portfolio of isolated (ADM248x/ADM249x) and nonisolated (ADM487E) RS-485 transceivers and has introduced RS-485 products that
include built-in power isolation (ADM2582E).
Critical specifications for an isolation solution include the insulation rating, maximum continuous working voltage, data rate, power
consumption, and channel count. ADI offers the broadest range of isolation ratings with products specified at 1 kV rms, 2.5 kV rms,
and 5 kV rms. Also critical is the lifetime at
which an isolator can operate at high voltage.

With more than 250 million energy meters using ADI’s technology deployed worldwide, Analog Devices has delivered
more energy measurement solutions than any other semiconductor company.
For metering communications, ADF70xx transmitters and ADF702x transceivers are well suited for short range
designs such as automatic meter reading (AMR), industrial automation, alarm and security systems, home
automation systems, remote controls, and other wireless network and telemetry systems where low power
consumption and very long range are required.
With the move toward more smart metering applications, the complexity of power management devices continues to
rise. ADI’s broad range of power solutions offers higher efficiency, smaller size, and lower cost than traditional solutions.
