摘要/Abstract

摘要： 为了准确模拟交直流系统的交互影响特性,有必要采用电磁暂态仿真分析方法。提出了一种将机电暂态仿真模型数据快速转换成对应的电磁暂态模型数据的方法。先在PSS/E中对大规模交直流系统进行等值简化,再将PSS/E中简化后的系统通过编程方法快速转换为PSCAD/EMTDC中电磁暂态仿真模型,最终在PSCAD/EMTDC中搭建出详细的交直流系统电磁暂态模型。运用所提方法对一个实际电网进行稳态验证和三相对称交流故障下的暂态仿真计算,验证结果表明,通过所提方法转换得到的PSCAD/EMTDC电磁暂态仿真结果与PSS/E机电暂态仿真结果一致,证明利用所提方法搭建的电磁暂态仿真模型是有效的。

Abstract: To study the detail interactions between the AC and DC systems, it is necessary to adopt the electromagnetic transient simulation method. A fast data conversion approach for large-scale AC/DC power systems is presented in this paper, which can convert electromechanical transient simulation models of large-scale AC/DC power systems to the corresponding electromagnetic transient simulation models. Firstly, the large-scale AC/DC power system is reduced in PSS/E; and then the reduced system in PSS/E is quickly converted to the electromagnetic transient simulation models in PSCAD through programming methods; and finally, the detail electromagnetic transient simulation models of the large-scale AC/DC power systems is established. The steady-state verification and transient simulation under 3-phase symmetric faults are done based on the established electromagnetic transient simulation models of a real power system, and the simulation results demonstrate the consistent responses of the simulation models in PSCAD and in PSS/E, which shows that the proposed fast data conversion approach is valid.
