摘要
介绍一种应用电磁暂态仿真程序 ( EMTP)进行供电系统谐波 (低次谐波 )潮流计算的方法。利用 EMTP软件确定了供电网络各元件的谐波模型及其参数。在此基础上建立了中性点不同接地方式的供电网络在稳态和不同故障情况下的暂态谐波分析模型 ,并对一个供电网络实例进行了5次谐波潮流的仿真分析 ,得到了较为满意的效果。
A method of simulation for calculating the harmonic (low orders) load flow in power supply system is presentedusing the electromagnetic transient program (EMTP). The harmonic models and parameters of different components in thesystem are determined. Then under the conditions of normal state and various fault cases, the transient harmonic analysismodels are built for power supply system with different grounding patterns. Finally, an example of fifth-order harmonic loadflow is simulated for a real system. The results demonstrate the effectiveness of the proposed method.
