Automatic Voltage Regulator AVR DECS-100-B11 for Basler Generator

Automatic Voltage Regulator AVR DECS-100-B11 for Basler Generator

The Basler Digital Excitation Control System (DECS-100) B11 is a microprocessor-based digital automatic voltage regulator. It can be used on almost any generator up to 5MW. It can put out 63Vdc and 7.0Adc continuous voltage and current and SENSE 100/120, 200/240, 400/480, 600Vac single or three phase.

The B11 specifically provides VAR/PF controlling, voltage matching, and 1A CT secondary, making the Basler Electric DECS-100-B11 a versatile voltage regulator.

Basler DECS-100 Features and Capabilities:

• Four control modes: automatic voltage regulation (AVR), manual or field current regulation (FCR), power factor (PF) regulation, and reactive power (var) regulation.

• Programmable stability settings.

• Soft start and voltage buildup control with an adjustable ramp in AVR control mode.

• Overexcitation limiting (OEL) and underexcitation limiting (UEL) in AVR, Var, and PF control modes.

• Underfrequency (volts/hertz) regulation.

• Three-phase or single-phase generator voltage (rms) sensing/regulation in AVR mode.

• Single-phase bus voltage (rms) sensing.

• Single-phase generator current sensing for metering and regulation purposes.

• Field current and field voltage sensing.

• One analog input for proportional remote control of the setpoint.

• Five contact sensing inputs for system interface.

• One common output relay for alarm indication and trip functions.

• Three protection functions: field overvoltage, generator overvoltage, and loss of sensing.

• Generator paralleling with reactive droop compensation and reactive differential compensation.

• Rear RS-232 communication port for personal computer communication using BESTCOMS Windows® based software for fast, user-friendly, setup and control.

Basler Electric DECS-100-B11 Product Description

The DECS-100 regulates the output voltage of a brushless, ac generator by controlling the current into the generator exciter field. Input power to the DECS-100 can be from a multipole, high-frequency, permanent magnet generator (PMG) or from the generator output when used as a conventional, shunt-excited, excitation system.

The DECS-100 is supplied in an encapsulated package designed for behind-the-panel mounting. The DECS-100 is held in place by thread-forming screws that thread into its plastic shell. Front panel indicators (LEDs) annunciate DECS-100 status and system conditions. DECS-100 connections are made through quarter-inch, quick-connect terminals on the rear panel. A 9-pin DB-9 type connector on the rear panel provides communication between the DECS-100 and an IBM compatible PC.
