Система возбуждения синхронного генератора

1. Introduction ME-WKLC-I Synchro Generator (or Motor) Excitation System, a kind of static self-parallel excitation system controlled by microcomputer, is mainly used as matching equipment for turbine-generator set. It is applicable to synchro generator with different voltage levels and capacities. Applying the latest technology and based on the design principle of “unattended operation, less manpower & maintenance-free”, this system is characterized by simple structure, easy operation and convenient maintenance. 2. Working Environment Environment temperature: -10°C 50°C Altitude: ≤2000M Relative humidity of ambient medium: ≤90% Free from conductive, explosive and corrosive gas or dust Vertical tilt should not exceed 10°, no fierce vibration indoor Power supply: 220V (±15%), 50HZ, 3-phase 4-wire 3. Main Functions This excitation system is provided with perfect functions of fault self-diagnosis, alarm,protection and display. The protections include disconnection protection, over excitation limitation, peak value limitation, low excitation limitation, under excitation protection, V/F limitation, false field-forcing protection and no-load over voltage protection. Functions in General: Disconnection protection; Over excitation limitation; Peak value limitation; Under excitation protection; V/F limitation; False field-forcing protection; No-load over voltage protection;
