中压动态无功补偿装置保护系统应用研究

Application of Dynamic VAr Compensation Protection System for Medium-Voltage Transformer Substation

对中压动态(晶闸管投切电容器)无功补偿装置的保护系统进行了研究,较详细地分析了可能发生的故障原因、现象,进行了理论计算,提出了保护措施,为保护系统的设计提供了一定的依据。产品的应用证明,该保护系统较全面地考虑了各种故障保护,简单、实用、可靠,其性能达到设计及工程要求。

The paper presents an improvement solution for TSC Dynamic VAr Compensation protection system. It discusses its failure scenario and reasons, and it gives an theory calculation, which helps to design a more reliable and effective reactive power compensation protection system.A VAr compensation protection system product based on this solution has been proved to be effective and reliable, its performance meets design specification and application requirements.
