Research on Stable Operation of Passive Filter in Power Distribution Network Reconfiguration

Network reconfiguration and capacitor switching are two main measures in power distribution network optimization, which plays a crucial role in power distribution automation. Along with the accelerated process of industrialization, the situation that distribution network optimization faces is more and more complicated. The originally safe operation of filtering and reactive power compensation devices may have a security risk in the optimization process of distribution network. Aimed at this problem, the constraint conditions of distribution network reconfiguration are researched, and the switching strategies of passive filter that could meet the security and stability requirements are discussed. Finally calculation and simulation are carried out with specific examples to verify the treatment effect, security and stability of the compensation devices, and consequently the stable operation of passive filter in distribution network reconfiguration is solved satisfactorily.
