Thông tin chi tiết

The Basler Digital Excitation Control System (DECS-100) is an electronic, solid-state, microprocessor based control device. 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.

FEATURES:

DECS-100 units have the following 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.
