中文摘要	采用分布式计算技术,研究并实现了基于集群计算机的保护定值在线校核并行计算方法。首先分析了保护定值校核计算的计算量和计算特点,接着对可能采用的并行计算方法进行比较,最后选择了基于电网分块的并行计算方法。采用协调机加计算子机的计算模式,在协调机上执行分块算法,通过基于主导节点的图划分方法把电网分成几块,每台计算子机只校核1块电网内的保护定值,最后由协调机收集汇总计算结果。现场应用证明,该并行计算方法正确、有效。; By means of distributed computing technology, a parallel computing method based on the computer cluster for online relay setting check is studied and developed. Firstly, the computing cost and characteristics of relay setting check are analyzed. Then the feasible methods are compared and finally the parallel computing method by means of power network partitioning is selected. The computer cluster is composed of one coordinating computer and some calculating computers. The graphic partitioning algorithm based on the seed node is executed in the coordinating computer and then the power network is divided into several parts. The relay setting in each part of the power network is checked by one calculating computer with the results collected by the coordinating computer. This method has been proved correct and efficient in actual application.; 国家重点基础研究发展计划(973计划)资助项目(2004CB217904); 国家自然科学基金重大项目(50595414); 国家自然科学基金资助项目(50323002)~~
