摘　　要：为进一步提高电网电磁暂态建模的效率和准确性,开发了机电暂态仿真软件PSD-BPA至电磁暂态仿真软件PSCAD/EMTDC电网模型自动转换程序。通过研究PSD-BPA和PSCAD/EMTDC电网模型(主要包含传输线、发电机、负荷和变压器模型)数据结构和参数特征,确立模型对应参数转换关系,并据此开发自动转换程序。以某省电网为例进行模型转换和仿真计算,经对比分析,转换后线路有功功率和无功功率相对误差均不超过1%,节点电压相对误差不超过0.1%,验证了该转换程序的准确性和可靠性。In order to further improve the efficiency and accuracy of the electromagnetic transient modeling of power grid,this paper studies and develops an automatic conversion program of power grid model from electromechanical transient simulation software PSD-BPA to electromagnetic transient simulation software PSCAD/EMTDC.The data structures and parameter characteristics of PSD-BPA and PSCAD/EMTDC power grid models(including transmission line,generator,load and transformer models)are deeply studied,the corresponding parameter conversional relation of model is established,and the automatic conversion program is developed accordingly.Taking a provincial power grid model as an example for model conversion and simulating calculation,through comparative analysis,the relative error of active power and reactive power of lines after conversion is less than 1%,and the relative error of node voltage is less than 0.1%,which verifies the accuracy and reliability of the conversion program.
