摘要
针对现有电力系统仿真计算软件如PSCAD等不能满足用户自主开发的需求,文章通过分析电磁暂态计算理论的离散化方法,建立了配电网电源、断路器、变压器、输电线路、接地开关等主要元件的离散数学模型,开发了配电网故障暂态计算程序。通过典型配电网络故障的仿真验证,结果表明所开发的暂态计算程序具有较高的精度,能很好地满足配电网故障多样化测试数据的需求。
To develop a transient calculation programming for distribution network which can meet the demands of users＇ selfdevelopment. We analysed the discrete calculation of EMTP Theory and built the discrete mathematics model of power source, circuit breaker, transformer, transmission line and grounding switch. The results of simulation indicated that the transient calculation programming is of relatively high precision and can meet the requirements of diverse testing data.
