摘要

断续电流试验是高压直流输电用晶闸管换流阀的一项重要的型式试验

该试验模拟换流阀在两种不同电压下电流产生断续情况

换流阀能够正常、多次可靠触发的能力。文中讨论了在合成试验回路基础上采用电流源双六脉动桥串并联运行、增加辅助取能装置或调节电压源时序的方法进行断续电流试验

并对上述几种方法进行了比较分析。经过试验验证的晶闸管换流阀在实际直流输电工程中的良好运行证明了合成试验回路断续电流试验方法上的等效性。

Abstract

Intermittent current test is an important operation test of the thyristor valves in HVDC transmission system

the test simulates the intermittent current of the thyristor valves at two different voltages

while the thyristor valves are capable of normal and multiple reliable triggers.Several methods of intermittent current test are discussed here including 6 pulse bridges of current source series or parallel operation

add auxiliary power extraction device

adjust the voltage source timing

the above methods are compared and analyzed in this paper.The successful operation of thyristor converter valves in HVDC projects proves the equivalence of the method of intermittent current test in synthetic test circuit.
