摘要:
工程中常采用计算机仿真对大电网的运行特性进行分析计算。其中机电暂态仿真主要对大电网整体的稳定性进行分析，电磁暂态仿真主要针对局域电网的动态特性进行研究，如电力系统过电压计算、保护及控制装置及直流电力电子设备开关特性等。我国电力系统数据主要沿用机电暂态仿真软件格式填写记录，电磁暂态仿真数据匮乏，因此需要将机电暂态数据转换为电磁暂态数据。本文通过对潮流数据和动态模型转换进行分析，针对PSASP和PSCAD两软件的共有模型(如发电机、变压器、输电线路、负荷及补偿器等)，进行参数比较后利用数学等值计算对模型进行转换，从而通过数学分析充分验证了PSASP模型向PSCAD转换的可行性。Digital simulation is usually utilized to analyze the operating characteristics of large-scale power grid, including electromechanical transient simulation for research on grid overall stability and electromagnetic transient simulation for study of local grid dynamic characteristics such as over-voltage calculation, protection configuration and DC power electronic switching device characte-ristics. However, power system data is mainly record as electromechanical transient simulation format and electromagnetic transient simulation data is quite poor. Therefore electromechanical transient data needs to be converted to electromagnetic transient data. For common model in PSASP and PSCAD software (such as generator, transformer, transmission line, load and compen-sator, etc.), this paper transform the model after comparing parameters using mathematical equi- valence, and fully proves the feasibility of transformation to the PSCAD PSASP model through ma-thematics analysis.
