Description

冲击电压复合的高压直流输电换流阀故障电流试验方法 技术领域
本发明涉及一种直流换流阀试验方法, 具体讲涉及冲击电压复合的高压直流输电换 流阀故障电流试验方法。 背景技术
随着高压直流输电技术在电力系统中应用的逐步推广, 其核心部件——大功率高 压串联晶闸管阀的可靠性成为系统安全的关键。而故障电流试验是关系到高压串联晶闸 管阀设计和制造水平, 提高其可靠性的重要试验手段。 其主要目的是验证换流阀承受短 路电流引起的最大电流、 电压和温度应力作用的设计是正确的。 目前普遍采用合成的试 验理念来进行直流输电换流阀的故障电流试验。 其基本思想是采用直流电流源、 故障电 流源、 高电压源等多套电源系统分别为换流阀提供加热电流、 故障电流和故障后的正反 向高压。 合成试验回路能够完成下面两项试验:
a) 后继闭锁的单波次故障电流试验——抑制一个最大幅值的单波次故障电流, 从 最高温度开始的, 跟着闭锁发生的反向和正向电压, 包括任何甩负荷造成的过电压; b )无后继闭锁的多波次故障电流试验——在与单波次试验相同的条件下, 直到断 路器跳闸前, 继续存在多波次故障电流, 但不再施加正向电压。
目前的试验电路中高电压源一般由 L、 C振荡电路构成, 它所提供的高电压波形正 负对称。所以对于单波次故障电流试验, 一般合成试验回路在故障电流熄灭后为试品提 供的正反向高压幅值大小相等。 而在实际工况中, 试品阀在经历故障电流后, 换流阀先 承受反向电压,然后电压上升直至达到正向峰值,且反向电压峰值要小于正向电压峰值, 在这个过程中试品阀节温逐渐降低。一般合成试验回路提供的反向过高电压对刚刚经受 故障电流节温偏高的换流阀很不利, 有损坏试品阀的可能。 此外, 实际工况中换流阀 所承受的正向电压峰值时刻是在其反向电压过零后 5ms, 对于一般合成试验回路, 为达 到此项要求必须修改电路有关参数, 既增加投资又给试验操作带来不便。 发明内容
