摘要
对PSS/E下常规双端直流系统的自定义建模展开了深入研究。首先,从深入研究了PSS/E自定义建模原理;然后,对直流自定义建模的方法,对建模中的关键问题,即换流器在机电暂态下的建模即改进,控制的建模,进行了深入分析;最后,以CIGRE直流输电标准测试系统为例搭建了自定义模型,并与PSCAD/EMTDC环境下的模型进行了仿真结果对比,验证了所建自定义直流模型的正确性和PSS/E自定义功能的实用性。
This paper studies in depth a user-defined modeling for the regular two-terminal DC system in PSS/E. After a detailed study of the principle of user-defined modeling, it analyzes the method for user-defined DC modeling and the Key issue of converter modeling in the electromechanical transient, namely an improved modeling under control. Finally, a user-defined model is established on the base of CIGRE standard testing system for power transmission, and simulation result is compared with the model in the PSCAD/EMTDC environment. The correctness of the established user-defined DC model and the practicability of the user-defined function of PSS/E are thus verified.
