励磁系统改造及相关问题分析

Excitation System Alteration and Analysis on Correlation Matters

针对华能上安电厂1号、2号机组励磁系统结构复杂、无逆变功能、灭磁时间常数较大的问题,提出具体的改进方案,重点分析了改造过程中励磁变压器的容量及温升以及灭磁方案等。

Aiming at the problems of excitation system from aspects of structure complexity, without inversion function, big field discharge time constant, the improvement project are advanced. The excitation transformer capacity, temperature changes,field discharge project are stressed.
