【摘要】 提出采用电磁暂态仿真软件EMTP的ATP版本作为大规模电力系统的暂态稳定仿真工具,用以解决机电暂态仿真程序所不能仿真的电力电子的快速暂态过程、非线性元件模型和系统不对称运行。通过对固定串补不同模型的分析,说明采用ATP-EMTP进行暂态稳定计算的必要性。通过对江苏苏北电网的ATP-EMTP和电力系统分析综合程序(PSASP)的潮流和暂态稳定的对比试验,验证了用ATP-EMTP进行大规模电力系统暂态稳定仿真的可行性。更多还原

【Abstract】 The ATP-EMTP is proposed for use as a transient stability simulation tool for large power systems. The purpose is to simulate the action process of power electronic equipment beyond the capability of the electro-mechanical simulation program and the asymmetrical operation of the nonlinear components model and system. An analysis of the model of a different fixed series compensator shows the necessity of using ATP-EMTP in transient stability simulation. Comparisons have been made between the power flow and transient stability results of Subei 220 kV and the above power system obtained from ATP-EMTP and PSASP, respectively. The results show that it is feasible to use ATP-EMTP as an excellent tool for large power system stability simulation.更多还原
