摘　　要：在电网无功补偿技术中,采用晶闸管动态补偿器,具有开关速度快、连续调节无功功率等优点,对于冲击性强、波动性大的无功负荷,可实时跟踪电压闪变,实现快速补偿无功功率,提高电网的稳定性。但实际运行中,由于采用电控晶闸管,其触发驱动电路TE板工作在高压电气环境中,受强电磁干扰,阀组的准确触发和可靠性下降。采用光控晶闸管作为阀组的核心功率器件,可实现触发保护系统与高压阀组的隔离,避免高压产生的电磁干扰,提高静止无功补偿器的补偿能力。The use of thyristor dynamic compensator has advantages of fast switching speed and continuous regulation of reactive power in the reactive power compensation technology of power network, for reactive power load with strong impact and high volatility, voltage flicker can be tracked in real time to compensate reactive power quickly and improve the stability of power network. Due tp the use of electronic control thyristor in practical operation, the trigger drive circuit TE board works in high voltage electrical environment, which is subjected to strong electromagnetic interference, and the accurate trigger and reliability valve group decrease. If the optical thyristor is used as the core power device of the valve group, the isolation between the trigger protection system and high voltage valve group can be realized, to avoid electromagnetic interference caused by high voltage and improve the compensation ability of static reactive power compensator.
