±500 kV宝鸡换流站是国家电网公司支援四川地震灾区的重点项目之一,文章详细介绍了该换流站交、直流滤波器调频调谐试验的全过程。首先依据滤波器的出厂参数通过软件仿真确定了谐振频率,参照相关调试标准确定了宝鸡换流站滤波器的调谐限值,再通过调节电抗器抽头并利用变频电源进行检测,最终使滤波器达到了设计要求。
± 500 kV Baoji Converter Station is one of the key projects supported by State Grid Corporation of Sichuan Province in quake-stricken areas in Sichuan Province. The article details the whole process of FM tuning test of AC and DC filter in this converter station. Firstly, the resonant frequency was determined by software simulation according to the factory parameters of the filter. The tuning limits of Baoji converter station filter were determined with reference to the relevant commissioning standards. Then the filter was adjusted by adjusting the reactor tap and using the variable frequency power supply to achieve the final filter The design requirements.
