Microcomputer controlled excitation system for synchronous generators

摘要

A new microcomputer controlled excitation system has been developed at Ganz Ansaldo Electric Ltd., primarily for power plant synchronous generators. The authors introduce the main characteristics of the excitation system: the redundant system configuration, the control functions and structure, the hot standby microcomputer system, the high-level man-machine interface and diagnostics. The prototype excitation system has been tested under power plant circumstances and the results are presented.
