摘要
为了提高电网的安全运行,开发了基于机电暂态-电磁暂态混合仿真原理的电网合环分析计算系统。利用机电-电磁混合仿真原理,提出了基于最大级数搜索算法的电磁网络自动划分方法,实现了机电暂态模型自动转换为电磁暂态模型的功能,并完成了地理图与厂站图相关联的功能,方便用户操作的同时提高了合环计算结果的准确性。利用开关统计功能,可以得到系统不同时刻的合环情况。通过对新疆喀什地区电网的合环仿真计算,其结果表明该系统能够提高合环操作的准确性,为合环操作提供了重要依据。
To improve safe operation of power network, a loop closing analytical calculation system based on electromagnetic- electromechanical transient hybrid simulation theory is developed. An automatic electromagnetic network partition solution based on the maximal stair search algorithm is put forward. The system also implements the function of automatic transformation from the electromechanical transient models to electromagnetic models and links the geographic maps and station maps, which not only makes loop closing operation easy but also enhances veracity. Simulation and calculation results show that the system can increase the accuracy of loop closing, providing evidence for loop closing operation.
