本文介绍一种基于微分方程隐式积分梯形公式的电力系统稳定计算隐式积分交替求解算法。该算法具有数值稳定性好、可采用较大积分步长、能够适应较长过程动态稳定模拟计算的特点，并具有显式积分编程简单可靠、便于扩展的优点。

This paper describes an implicit integration alternating solution method for power system dynamic stability simulation. The method is based on the trapezoidal rule of implicit integration in solving differential equations,which is numerically stable. The time step size of the integration in this method may be much longer than that in explicit method. It has a good ability for long time dynamic stability simulation due to its numerical stability. The method is programming simplicity, reliability and flexibility as explicit integration methods in solving the algebraic and differential equations separately.
