PSASP2ATP暂态模型参数转换研究及软件研发

Conversion of PSASP2ATP Transient Model and Parameters and Software Development

为了充分利用电力系统分析综合程序PSASP在现实电网中数据、分析和运行的积累与充分发挥电磁暂态计算程序ATP暂态分析和底层开发之优势,研究了PSASP软件中暂态模型和参数转换到ATP软件的基本方法。通过比较2款软件中电气元件暂态模型的异同,采用分模块转换方法,建立在软件内部对应元件模型、参数、数据的对应关系和转换途径。在VC6++环境下开发出由PSASP到ATP暂态模型参数转换的软件PSASP2ATP,能方便地实现大型电网电磁暂态模型的数据转换。利用IEEE 9节点系统和含直流输电的某省局部电网的算例测试结果表明了所提内容的有效性。

In order to make full use of the analysis and operation data of power system analysis software program(PSASP)in a real power grid,and to give a full play to the advantages of electromagnetic transient calculation program ATP transient analysis and underlying development,this paper conducts a study on the basic method of transient model and parameter transformation from PSASP software to ATP software.By comparing the similarities and differences of the transient models of the electrical components in the two softwares,the corresponding relationship and conversion routine among the models,parameters and data in the software is established by using module conversion.Under the environment of VC6++,the software PSASP2ATP is developed,converting the parameters of the transient electromagnetic model from PSASP to ATP.The test of the conversion software is carried out with the example of IEEE 9-node system and a provincial local power network with DC transmission.The results verify the effectiveness of the conversion method.
