BPA向PSS/E的数据转换及暂态稳定比较研究

Data Conversion and Transient Stability Analysis between BPA and PSS /E

BPA和PSS/E均为机电暂态仿真软件,两者潮流数据和暂态模型具有较好的相似性,在对BPA和PSS/E两种仿真软件的暂稳态数学模型分析和比较的基础上,提出了BPA向PSS/E数据转换的详细方法,并通过某交直流系统进行仿真测试,对潮流计算结果和稳定计算结果进行了对比分析,仿真结果表明两者潮流基本一致,暂态仿真结果相似,暂稳态过程基本吻合,表明BPA数据可以准确的转换为PSS/E数据,实现数据共享。

BPA and PSS/E are both electromechanical transient sinlulation softwares, which are similar in transient and steady models. Based on analysis and comparison of these models, this paper proposed a detailed method to change BPA data into PSS/E format and checked the accuracy through an AC-DC system simulation test. The result of simulation comparison shows that power flow and dynamic simulation result is barely the same, so the data conversion is successful.
