论述了大规模交直流电力系统并行计算数字仿真方法。首先,介绍了4种可并行计算的电力系统数字仿真工具,对各自特点和适用性进行了分析。其次,对比研究了基于频率响应的等值方法、Ward等值方法以及基于物理等效的动态等值方法等3种电力系统等值方法,并分析了各自的优缺点。然后,从模型转换与对应、元件布局与连接以及子系统划分与分核3个方面,详细研究了基于PSCAD/EMTDC仿真工具的交直流大系统并行计算方法。同时,全面分析了基于RT-LAB的大规模交直流电力系统并行计算方法,并对系统的初始化进行了详细分析。
This paper discusses the digital simulation methods with parallel computing of large-scale AC/DC power systems. Firstly, we introduce four power system simulators with parallel computing capability, and analyze their characteristics and applicability. Secondly, we compare three equivalent methods of power system including : the equivalent method based on frequency response, the Ward equivalent method and the dynamic equivalent method based on physical equivalent and analyze their advantages and disadvantages. Then, we study the parallel computing method of large-scale AC/DC power system based on PSCAD/EMTDC simulator in detail, from three aspects of model transformation and correspondence, element layout and connection, subsystem division. Meanwhile, we comprehensively analyze the parallel computing simulation method of large-scale AC/DC power system based on RT-LAB, as well as the system's initialization in detail.
