FWL/B Static Excitation System for Synchro Generator

Introduction

The system configuration includes computer digital AVR, thyristor rectifier, non-linear  de-excitation and over voltage protection, transformer, operation protecting and controlling system etc.

Functions

Simple structure, convenient operation and maintenance, high action response speed, and high action reliability.

• The AVR uses 32-bit DSP as the core, and adopts  high precise multi-point AC sampling technology, and all the control, regulation, protection function are realized by the module software. It also can be regulated by the 3-D graph, can modify, control and adjust the parameters on line, and has the intelligent function of fault-tolerant , filtering, self-detecting and self-diagnose etc. 
• De-excitation with linear or nonlinear resistor and field breaker.
• non-linear over voltage protection.
• Configure 100 KVA~3000KVA excitation transformer of all types.

Technical Parameters

• Voltage regulating range: 1%~130%UFM
• Voltage regulating precision: <0.25%
• Celling excitation: 1.6~2.5 times
• When starting excitation from 100%, super regulating amount <5%, oscillating times <1 time
• MTBF: 30000 hours
• Other performance indexes reach or excel GB/T740913-1997 and DL/T583-1995
