摘要
文中研究了特高压换流站内交流滤波器的电压控制原理及功能,通过对一起典型换流站交流滤波器误投入案例的分析,指出交流电压控制程序中可能存在的导致交流电压基准值发生选择错误的缺陷。同时结合交流滤波器在各类运行方式下程序判断中的薄弱环节,提出针对性的优化措施,并通过RTDS仿真试验平台对此类优化措施的正确性及可靠性进行验证。
The voltage control principle and basic functions of the AC filters in a UHVDC converter station are described. By analyzing a typical misconnecting failure of AC filter in a UHVDC converter station, it is found that a defect, which will lead to selection error of voltage reference, may exist in the AC voltage control program. So some optimization measures are presented to overcome the judgement weakness in the program under different operating modes of the AC filter. In addition, the validity and reliability of the measures are verified on the RTDS simulation testing platform.
