| 中文摘要 | 针对高阻接地方式的船舶中压电网,提出一种系统化的暂态短路电流计算方法。考虑同步发电机及异步电动机暂态特性,根据故障点位置,基于分层等效方法将系统中所有发电机和电动机等效为一台发电机。对于等效发电机,考虑系统分布电容,用对称分量法求解三相对称及各种不对称故障的暂态电流。用Simulink仿真结果对比验证了该方法的有效性和精确性。; A systematic calculation method for transient short circuit current is presented for the shipboard medium-voltage(MV) power grid with high resistance grounding. Considering the transient characteristics of synchronous generator and asynchronous motor, according to the location of short circuit, all generators and motors in the system are equivalent to a generator based on the layered equivalent method. For the equivalent generator, the transient currents under three-phase symmetrical and various asymmetric faults including system distributed capacitance are solved by using symmetrical component method. Simulink simulation results verify the validity and accuracy of the method. |
