励磁功率整流装置均流系数一般要求不小于0.85,且励磁功率整流器配置冗余度要按全部功率整流器的并联支路数中有一支路退出运行后,剩余支路仍能满足发电机的所有运行工况要求进行参数配置,这一要求在电力行业各类励磁标准中均有明确规定。本文针对整流装置均流系数超差的各种原因进行分析阐述,提出了相应的解决方法,满足了现场设备的稳定运行要求。
Excitation power rectifier current sharing coefficient of not less than the general requirement of 0.85, and the excitation power rectifier configuration redundancy according to the full power rectifier parallel branch number of a branch out of operation, the remaining branch still meet all the generator operation Conditions require configuration parameters, this requirement in the power industry all kinds of excitation standards are clearly defined. This paper analyzes and expounds various reasons of overcurrent sharing coefficient of rectifying device, puts forward corresponding solutions to meet the requirements of stable operation of field devices.
