摘要: 电网的密集发展导致近年来短路电流超标问题日益突出,相间功率控制器(IPC)由于其良好限制短路电流特性渐受关注。采用运算电路法对含IPC的系统短路故障电路进行分析,得到IPC支路短路电流的详细表达式,分析影响IPC的短路冲击电流的因素,提出计算含IPC系统的短路冲击电流方法。以一个含IPC的500 kV等值系统为例,采用电磁暂态仿真程序对其进行短路故障仿真,结果证明所提方法的可行性。研究成果可为IPC设备选型提供参考。

Abstract: In recent years, intensive grid developments led to short-circuit current overproof increasingly. Therefore, interphase power controllers(IPCs) are receiving attention due to its characteristics of limiting short-circuit current. The system with short-circuit faults, which also contains IPCs, was analyzed by the operation circuit method in this paper, and the detailed expressions of IPC branches’ currents were also conducted. Based on the expressions, the analysis of the influence factors on the short-circuit impulse currents of IPCs as well as the methods of calculation were accomplished. Finally, an equivalent system of 500 kV, containing IPCs, was taken as an example to get the electromagnetic transient simulation results, which prove the feasibility of the proposed method. This research can provide a reference for the selection of interphase power controlles.

Key words: interphase power controller, short-circuit impulse current, operation circuit method, electromagnetic transient simulation
