Benefits with AGC-4

Easy installation with CAN bus

A dedicated J1939 CAN bus connection provides efficient and

exclusive communication between the DVC and the controller.

This makes it possible to, for example, quickly and easily swap

between nominal voltage or frequency settings for a generator.

Avoid genset over-sizing

Use magnetisation boosting or inductive motor starting to limit

the stator current during start-up. This reduces the need to start

multiple gensets when connecting a heavy load, and reduces

genset over-sizing requirements to a minimum.

Protect the genset from humidity

Drying: Condensation on the windings can be removed using the

genset drying mode. During drying mode heat generated from a

controlled short circuit is used to evaporate condensation on the

windings. The genset cannot be connected to the busbar until it is

safe to do so.

Ventilation: Use the genset ventilation mode to prevent

condensation forming on the windings by removing built-up humid

air using the alternator fan. Power generation is postponed until

the humidity levels are safe.

Fast backup for critical power applications

Use run-up synchronisation to start multiple gensets at the same

time while the gensets are connected to the busbar.

Gridcode compliance

The DVC 550 fast reaction speed complies with European

gridcodes. By combining the fast reaction speed with the AGC

controller, it is easy to comply with advanced gridcodes, such as

VDE 4105 and VDE 4110.

General description

The DVC 550 is a digital automatic voltage regulator, which

monitors and regulates the alternator output with rated field

current up to 7 A and voltage supply up to 277 V AC.

It is designed for alternators with SHUNT, AREP (auxiliary

winding) or PMG (permanent magnet) excitation types.

The DVC adjusts the excitation current in the exciter field

according to the desired alternator output.

The DVC 550 includes several protections and functions to keep

the alternator running in full safe operation.

The utility software, DEIF EasyReg Advanced, provides a visual

interface to configure values and parameters. The intuitive

interface makes it fast and easy to monitor and troubleshoot.

EasyReg can also be configured directly with the USB port

without external power supply.

Powerful, fast and compact, the TAS units in DEIF’s transducer range measure power

or reactive power on a 1- or 3-phase AC network and provide output signal as

direct current or voltage signal proportional to measurements for PLCs, PCs,

microprocessor control, indicators, alarm units etc.

TAS transducer ranges are micro-controller-based with one analogue output for

measurement of power, voltage, current etc. on an AC network.

Because these transducer rangers have no mechanical parts like potentiometers,

the calibration stability is excellent.

TAS transducers range can be delivered pre-configured to set measuring

values and ranges or un-configured for customer configuration using DEIF’s free PC tool.

To ensure stable and reliable operation of a wind turbine, the power supply is critical.

Most standard industry power supplies are not designed to cope with the real-life

operation demands of a wind turbine – operation temperature span, mechanical robustness,

tolerance towards ESD, etc. That is why DEIF Wind Power Technology has designed

a series of rugged DC supplies to support the second-to-none reliability of our control systems.

The power supplies feature compact and lightweight switchmode design and at the same time

– similar to conventional transformer designs

– they have no moving parts as they have been designed for convection cooling,

thus no maintenance-demanding fan is required.

The series of power supplies is designed for an operation temperature range of -40°C to +70°C,

supporting reliable start-up and operation regardless where in the world the wind turbine is operating.
