摘要
运用概率型算法对交直流混合系统可用输电能力(ATC)进行计算时,由于实际电力系统规模庞大,设备数目众多,而且并不是所有枚举的故障状态都对要分析的系统产生影响,故通过故障排序筛选出对系统影响大的严重故障。在交流故障排序法的基础上推导了适合于交直流混合系统ATC计算的故障排序法,通过算例验证,该法在不影响计算精度的前提下节约计算时间,提高计算效率。
Serious failures are selected by failure ranking when we calculate the available transfer capability(ATC) of AC-DC hybrid system by using Probabilistic algorithm,because the power system and the number of equipment are so large and not all failure states have impact on the system.In this paper,on the basis of failure ranking the method suitable for ATC calculation of AC-DC hybrid system is derived.Simulation results show that the method does not affect the accuracy and save computation time and improve efficiency.
