摘要
针对电网运行可靠性评估计算量大,但又要求计算时间短的问题,提出了一种基于分布式计算的电网运行可靠性评估算法。该算法采用改进的状态选择和分析方案,解决了计算终端间随机数序列的关联性问题,有效地降低了通信量,提高了计算速度。基于该算法编制的评估软件已通过RTS-24系统和某省级电网的实际运行测试,测试结果表明,该算法不仅能够有效评估电网运行可靠性,而且计算速度随计算终端数增加呈一定倍数提高。
In view of problem that evaluation for operational reliability of power grid has large calculated amount,but requires short computing time,the paper proposed an evaluation algorithm for operational reliability of power grid based on distributed computing.The algorithm uses improved state selection and analysis solution to solve the relevance problem of random number sequence between computing terminals,effectively reduces communication traffic and improves computing speed.Evaluation software based on the algorithm has passed RTS-24test system and actual operation test of a provincial power grid,and the test results show that the algorithm can effectively evaluate operational reliability of power grid,and the computing speed increases by a certain multiple with the increase of number of computing terminals.
