摘要
高压直流传输系统的整流器在开启、关闭、触发和晶闸管保护等方面存在很多问题,如系统的动态稳定性差并且不能有效地降低动态干扰。针对以上问题,提出了一种自校正模糊PI控制策略,并简要地介绍了该控制策略的设计过程,最后通过仿真验证了该设计的优势。
In the rectifier of traditional HVDC system,turning on,turning off,triggering and protections of thyristors have lots of problems that can make the dynamic instability and cannot damp the dynamic disturbance efficiently.In order to solve the above problems,fuzzy-PI control strategy with and without self-tuning for the fire angle control of rectifier has been proposed.A simulation comparative study has been performed to prove the superiority of the proposed scheme.
