摘要
目前晶闸管控制或晶闸管投切型高压静止无功补偿装置(TCR/TSC型SVC)在电力系统得到广泛应用,其中由晶闸管组成的阀组因功耗大,多用水冷系统散热。在电压等级35 kV及以上、容量120 MVar以上的工程中,晶闸管阀组为满足高电压、大电流系统需要,将要提高晶闸管容量和串联数量,水冷散热系统也要相应增加管路器件来保证散热能力。对原有大容量晶闸管阀组水冷系统管路建立模型,通过理论计算,提出改进方法,并进行试验前后对比,达到提高装置性能并降低成本的优化目的。
At present the high voltage static var compensator of thyristor control or thyristor switch(TCR/TSC SVC)has been widely used in power system, which is composed of a thyristor valve group for large power consumption, more water cooling system cooling. In the 35 kV voltage grade or above, above 120 MVar capacity in engineering, thyristor valve in order to meet the needs of high voltage, high current system, will improve the capacity and the number of thyristor series, water cooling system should be increased to ensure pipeline device heat dissipation capability. The valve cooling system piping model of the existing large capacity thyristor is built and the improvement method is put forward through theoretical calculation, the tests before and after are compared in order to improve the device performance, reduce the cost of optimization objective.
