摘　　要：电力输变电系统中的工频电场数值计算对于输变电系统的设计建设至关重要,而传统的方法在Matlab环境下求解三维电场耗时过多,本文以500 k V特高压输电走廊下电场计算为模型,基于Open MP多核并行环境,采用Matlab和C语言混合编写模拟电荷法的并行算法,既利用了Matlab生成矩阵的便捷性和对数据图像处理的强大功能,又利用了C语言的对于计算的快速编译性以及对于并行计算的可塑性,实现并行加速的效果,为解决数值算法求解三维工频电场的耗时问题提供计算平台。The calculation of power frequency electric field in power transmission and transformation system is very important for its design and construction. However, the traditional method takes too much time to solve three-dimensional electric field with Matlab. In this paper, the electric field under 500 k V UHV transmission corridor is calculated, based on the Open MP multi-core parallel environment, the parallel algorithm of simulating charge method is written by using Matlab and C language. It not only takes advantage of the convenience of Matlab to generate matrix and the powerful function of data image processing, but also makes use of the C language＇s compilation and the plasticity for parallelism. As a result, it realizes the parallel accelerating effect, and also provides a platform for three-dimensional electric field calculation.
