摘要
笔者介绍了±1 100 kV/5 000 A换流阀的基本结构,分析了在交流系统故障时限制换流阀运行电流的因素。当交流系统出现对地故障时,就会引起换流站交流母线电压降低,从而影响换流阀的运行条件。以西电电力系统公司自主研制的±1 100 kV/5 000 A换流阀为例,通过主回路参数的计算及晶闸管结温的计算结合实际运行工况分析了±1 100 kV/5 000 A换流阀在交流系统故障时的运行能力。
The author introduces the basic structure of ± 1 100 kV/ 5 000 A converter valve, and analyzes the limiting factors of converter valve operation current. AC system ground fault which cause the converter station AC bus voltage reduced will affect the operating conditions of the converter valve. Take the± 1 100 kV/5 000 A thyristor converter valve which is produced by Xi＇an XD Power Systems Co., Ltd. for an example, through the main circuit parameter calculation and thyristor junction temperature calculation based on the actual operation condition analysis of the ±1100 kV/5 000 A converter valve in the AC system fault operation ability.
