摘要
随着电力系统规模的不断扩大和对在线分析要求的不断提高,传统的分析计算方法受到前所未有的挑战。在牛顿法的基础上,提出一种可用于电力系统暂态稳定计算的时间并行计算新方法——牛顿下山法,以代数方程组和微分方程组的求解为线索,通过对并行算法在电力系统分析计算中的应用进行总结,从理论上对牛顿下山法进行分析,最后通过对5节点系统测试系统的仿真计算,证明了牛顿下山法具有很好的收敛性和很少的迭代次数,表明了该方法的有效性和实用性。
With continuous improving requirements of the power system and expanding the size of the on-line analysis, the traditional method of calculation analysis meets with unprecedented challenges. On the basis of the Newton method. Newton descent method is presented, which is a new parallel algorithm method of the transient stability in power system. Taking solving of algebraic equations and differential equations as clues,applications of parallel algorithm in power system analysis are summarized and Newton descent method is theoretically analyzed. Finally the simulation of five-bus system shows Newton descent method has a good convergence and a small number of iterations,and the method is effective and practical.
