摘要:

随着用电需求的增长和电网网架的日益增强，有必要考虑动态负荷对短路电流的贡献，以便更符合实际地评估断路器的开断能力、动稳定等。利用PSS/E的IPLAN语言编程，调用PSS/E API子程序和PSS/E API批命令进行一系列计算，灵活设置PSS/E数据卡片，改进了PSS/E BKDY模块使其可以考虑动态负荷进行短路电流计算。分别用上述改进模块和PSS/E暂态稳定模块，考虑动态负荷对我国某大都市电网进行了短路电流周期分量衰减计算，两者的计算结果非常接近。表明改进模块可以考虑动态负荷用来计算短路电流周期分量。

Abstract:

With the growth of electricity demand and the enhancement of power grid network, it may be necessary to consider the contribution of the dynamic load to the short-circuit current for the more realistic assessment of the circuit breaker breaking capacity and dynamic stability. The PSS/E BKDY module is improved by applying the IPLAN language embedded in PSS/E to call PSS/E API routines and PSS/E API batch commands so as to set PSS/E data cards automatically according to user defined rules and calculations. The short-circuit current of a metropolitan power system is calculated with both the improved PSS/E BKDY module and PSS/E transient stability module and the results from those two module are very close. Therefore the improved PSS/E BKDY module is verified to be able to calculate the short-circuit current decay with dynamic load considered. This work is supported by National High-tech R & D Program of China (No. 2011AA05A106).
