无刷同步交流发电机瞬态特性误差分析

Transient Characteristic Error Analysis of Brushless Synchronous Alternator

基于某实际项目对现场未知风机负载的突加性能试验失败为起点,找出影响发电机突加性能的技术参数,通过对比该发电机出厂时的两种风机负载试验与国标型式试验,分析项目发电机的瞬态性能不能满足现场负载的原因,通过优化同步发电机瞬变电抗参数,满足实际的需求,并给出使用建议。

Based on the failure of sudden performance test of unknown fan load on site in an actual project,find out the technical parameters which affect the transient characteristics of the generator,this paper compares the two fan load tests and national standard type test of the generator when it leaves the factory,analyzes the reasons why the transient performance of the generator in the project can not meet the on-site load,and meets the actual needs by optimizing the transient reactance parameters of synchronous generator,Suggestions for use are given.
