摘要
环形供电网络在舰船上被广泛应用,为了准确计算环形网络的短路电流,本文采用发电机的等效处理来计算环形网络的短路电流,通过发电机与阻抗串联和与其他发电机进行并联从而将网络简化,并使用MATLAB中的Sim-powersystems工具箱对实例进行仿真验证,结果表明该方法有较高的准确性和精度,为复杂结构的电力系统的短路电流计算奠定了基础。
Annular grid has been widely used on ships, In order to accurately calculate the short circuit current of the annular, In this paper, using the equivalent generators to calculate the short circuit current on annular grid, the equivalent generators via generator with impedance in series and then parallel with other generators to simplify network, and use Simpowersystems toolbox in MATLAB to simulation instance, the results show that this method has higher accuracy and precision, Laid the foundation for the complex structure of the power system short-circuit current calculation.
