摘要:
为降低超高压线路潜供电流数值、改善单相重合闸条件,针对传统补偿方法的不足,提出了一种利用相间并联电抗器来取代中性点小电抗补偿相间电容的方法,从而在系统正常运行时,使相间电抗器成为并联补偿装置的一个组成部分,与相地可控电抗器构成两级补偿装置,同时起到无功补偿和抑制系统潜供电流的作用。针对已知参数建立了500 kV 系统联络线的仿真模型,进行了仿真计算,并在电力系统动态模拟实验室中建立了500 kV 系统模型的低压实验平台,通过仿真和实验结果的对比验证了所提出方案的正确性和有效性,最后分析了高补偿度下单相断开后的谐振现象及其抑制方法。
Abstract:
In order to reduce the secondary-arc current in the ultra-high-voltage ( UHV) lines and improve single phase switching condition,aiming at the deficiency of traditional compensation method,a new method is put forward. The interphase parallel reactor was used to compensate the capacitive coupling instead of neutral point grounded by small reactance in this method. The interphase parallel reactor became a part of parallel compensation during normal operation of the system. The combination of interphase parallel
reactor and phase-ground controllable reactor became the two-level compensation. It played the role of reactive power compensation and suppressing secondary-arc current in the system. According to the known parameters, the simulation model of 500 kV system tie-line was established and the simulation calculation was carried out. The low-voltage experimental platform of a 500 kV system model was established in the dynamic simulation laboratory of power system. The correctness and the effectiveness of the proposed scheme were verified by simulation and experimental results. The resonance phenomenon of singlephase disconnection with high compensation and its suppression method were analyzed.
