Study On Interconnected Network On-line Overload Correction

Overload corrective control is a most important subject of power system real-time safety monitoring, and it is a linear combinative optimum problem of multivariate and multiple constraint. This paper firstly introduced the effectiveness algorithm of interconnected network on-line overload correction,use the approximate model of fast decoupled load flow ,use active power security correction and reactive power security correction at the same time. Further more,this paper introduce parallel algorithms into the overload corrective control to settle the problem that the computing speed of classical serial algorithm is not fast enough to suit the application of on-line overload correction .This paper adopts MPIch.nt.1.2.5 as operating platform and the MPI (Message Passing Interface) transfer function database to realize parallel communication. Finally, this algorithm is used in two cases and the result proves the correctness of this algorithm and achieves satisfying parallel accelerator through comparison with traditional algorithms.
