Analysis and Optimization of Current-sharing Rectifier Circuit of Generator Excitation System

励磁系统并列运行的可控硅整流桥需具有良好的均流系数,才能保证励磁系统的调节性能及安全可靠运行。分析了造成可控硅整流桥不均流的原因,并提出了有效解决均流效果的方法,为现场励磁系统均流性能的提高提供借鉴,具有一定的参考价值。

In order to ensure the regulation performance and the safe and reliable operation of the excitation system,an appropriate current sharing coefficient is needed for the thyristor rectifier bridge running in parallel with the excitation system.In this paper,the cause of non-uniform current of thyristor rectifier bridge is analyzed,and the effective method of realizing satisfactory current-sharing effect is put forward.The paper is expected to help in improving the current-sharing performance of practical excitation systems.
