摘要

高压直流输电工程中的整流站和逆变站运行时需要补充大量的无功功率

同时换流装置在运行时产生的谐波会造成电能质量下降

通信系统受到干扰

因此

为了补偿无功和抑制谐波

需要在交流侧和直流侧安装相应容量的滤波器。交流滤波器是特高压直流换流站不可缺少的重要组成部分。为确保换流站交流滤波器调试顺利进行

应用电磁暂态仿真软件EMTPE程序对750 kV交流滤波器操作过电压水平进行预测。在某换流站交流场系统调试时

分别对12组交流滤波器进行了投切试验。通过试验对交流滤波器的绝缘、保护以及开关特性进行了考核

并对试验中的数据进行了记录和分析。结果表明

仿真计算和现场实测基本吻合。750 kV断路器合闸电阻在退出时刻

对滤波器涌流有一定影响。

Abstract

A large number of reactive power are needed to be supplemented in the operation of rectifier station and inverter station in the HVDC project and

at the same time

the harmonic of converting device generated in the operation can cause reduction of power quality and interference of communication system.Therefore

the filter with corresponding capacity is needed to be installed on both AC and DC side for the reactive compensation and harmonic compression.AC filter is an important and indispensable part of UHVDC converter stations.For assuring smooth commissioning of AC filter at converter station

the EMTPE program is used to predict overvoltage of 750 kV AC filter.During the commissioning at AC site of certain converter station

12 groups of AC filter are subject to the switching test respectively.The insulation

protection and switching feature of the AC filter are checked by the test

and the data in the test is record and analyzed.It is shown by the simulation that the simulation calculation and the actual measurement are basically in agreement.The closing resistor of 750 kV circuit breaker

in case of removal from operation

has a definite influence on the inrush current of filter.
