摘要/Abstract

摘要： 电磁式电压互感器（TV）是配电网中测量和保护的重要设备，其高压侧装有熔断保险，实际运行中经常发生异常熔断。针对该问题，从电路原理分析故障成因，通过实时数字仿真平台（RTDS）验证理论分析，并得出铁磁谐振和低频非线性振荡等异常状况下的电压电流特征。分析并提出一种改进的微机消谐措施，证明其在一定范围有效，针对其使用的局限性提出将其与高饱和点TV方法结合，得到了更好地抑制过电压和过电流效果。最后，在此基础上对几种已有抑制措施进行验证对比，总结各方案可行性。

关键词: 电磁式电压互感器, 铁磁谐振, 保险熔断, 消谐, RTDS仿真

Abstract: Potential transformer (TV) is an important equipment for measurement and protection in distribution network. The high voltage side of TV is usually equipped with fuse for protection, but abnormal fuse blown often occurs, affecting the safety of power system. In order to solve this problem, this paper analyses the causes of the fault from the circuit principle, and verifies the theoretical analysis using RTDS simulation platform, and obtains the voltage-current characteristics under abnormal conditions such as ferromagnetic resonance and under-frequency non-linear oscillation. An improved method for resonance elimination is put forward and analyzed, and proves valid. In view of its limitations, it is proposed to combine the proposed method with the high saturation point TV method, which can better suppress over-voltage and over-current. Finally, on this basis, several existing countermeasures for fuse blown are verified and compared, and the feasibility of various schemes is summarized.

Key words: potential transformer, ferromagnetic resonance, TV fuse blown, resonance elimination, RTDS simulation
