摘要
故障计算是电力系统最基本的计算。随着电网规模与电力节点数日益增大,计算需要花费的时间越来越长。传统的串行计算方法已不太可能在计算速度上获得实质性进展,多核并行计算正引领着软件的研发方向。介绍了Open MP编程技术和故障计算原理,并基于Open MP编写故障计算程序,提出并行故障计算方法。通过用串行和并行两种方式对系统进行故障计算测试,仿真结果发现并行计算的时间明显低于串行计算,的确是一种低成本、高效率的解决方案。
Fault calculation is the basic computation in power system. With the increasing node number and covering area of power grids,it takes much more time to calculate than ever. Calculation and analysis are facing serious challenges,and traditional serial computing methods have been unlikely obtained substantial progress on computing speed,multi-core parallel computing is leading software development. The technology of Open MP-based parallel computation is introduced. The basic principle and model of fault calculation are analyzed. By using serial and parallel ways respectively to calculate the time for fault testing. Simulation results show that the time was significantly lower than the serial parallel computing,and the validity of the method is tested through the experiment.
