摘　　要：根据并行计算机算法特点,综合运用网络分割法及隐性梯形数值积分法,建立了电网子系统及其暂态方程。通过对电网通讯结构的分析,确定了并行程序的设计方法,基于Matlab对并行计算机算法下的电网暂态过程进行数值模拟,结果表明,电网系统的电压、功率及转子角速度的变化幅度较小而且平稳,系统稳定性较高。According to characteristics of parallel computer algorithm, with the using ot network segmentation method and implicit trapezoid numerical integration method, the power subsystem and the transient equation is established. According to the analysis of network communication structure, the design method of parallel program is determined. Numerically simulate of the power grid transient process is accomplished based on Matlab with using parallel computer algorithm, and the results show that the vohage, power and rotor angular velocity of power grid system is changing during quite small range with stable and high stability.

关 键 词：并行计算机算法 暂态方程 子系统 MATLAB
