摘　　要：基于"在线预决策、实时匹配"和"集中管理、区域控制"的思想,提出了一个应用于电力系统暂态稳定综合控制的并行计算框架。采用粗粒度暂态稳定空间并行算法,按照区域分配预想故障集,可以获得较大的并行加速比。并行计算网络采用PC集群系统,由FORTRAN90调用MPI传递库函数进行编程。边界系统的计算放在主机上,采用动态多线程技术并行实现,缩短了网络方程串行部分的计算时间,解决了事件处理时计算量突增的问题。从控制的经济性考虑,吸收了目前实用动态安全域领域的最新研究成果,采用预防控制与紧急控制的协调可以使得控制成本最小化。Based on the idea of ＂online pre-decision,real-time matching＂ and ＂Centr-alized management,regional control＂,a distributed network-computing framework is proposed for large-scale power network transient comprehensive control.By using a coarsegrained parallel-in-space algorithm for transient stability and allocating the contingencies to the networked computers according to different regions,the method can obtain large parallel speed-up.PC cluster system is used in parallel computing neteork.,Programed by FORTRAN90 calling MPI transmission library functions.Calculation of the border system is put on the host computer,implemented by the dynamic multi-threadi-g parallel technique,shortening the computing time of serial part of the network equations,solving theproblem that the calculatedamount suddenly increases when handling the emergencies.Considering the economic of control,absorbed the current up-to-date research result in practical dynamic security region,using coordinations of preventive control and emergency control can minize the control costs.
