摘　　要：对隐式梯形积分公式进行改进,引入加权因子,并采用显式格式迭代求解隐式方程组,对电力系统动态稳定进行计算。仿真结果表明,加权隐式梯形积分交替求解算法不仅保持了隐式积分数值稳定性好、可采用较大步长的特点,而且具有显式积分编程简单可靠、便于扩展的优点。同时,相较于梯形法,该算法能够消除网络操作引起的数值振荡问题,可用于电站或电网的仿真培训软件系统开发的后台仿真计算。The implicit trapezoidal integration formula has been improved by adding weighting factor and the use of explicit iterative solution of the implicit form of equations for the calculation of power system dynamic stability.Simulation results show that weighted alternating implicit trapezoidal integration algorithm not only maintains the implicit integration numerical stability,allso can be characterized using a larger step size.And it also has advantages of explicit integration＇s simple,reliable and scalable programing and easy expansion.Compared with the trapezoidal method,the proposed method can eliminate numerical oscillation caused by network operation problems,which can also be used for background calculation developed by simulation training software system of power plants or power grid.
