摘要
分析了高压电动机的故障特征和现有保护的不足。基于对称分量法，提出了基于检测正序、负序、零序电流分量的电动机保护方法，所研制的微机型电动机成套保护装置，保护齐全，功能完善，性能优良可靠，可应用于大中型异步电动机及同步电动机。
The paper analysed generator's trouble character and present protection's insufficient, based on symmetry parts theory, presents aprotection way by testing powitive order, negative order and zero order parts, the microcomprter generator protection device of being developed, protection complete, fnction perfect, property fine deperdable. It may beappliation of middle of large generator.
