As the require of v~ng order and step size for the numericalintegration, a differential-algebraic equations simultaneous solutionmethod based on Gear Method are adopted as the main numericalsolution algorithIns fOr network solution.

• 根据电力系统全过程动态仿真的数值积分的变阶变步长的要求，本文提出采用联立求解微分一代数方程法作为电力系统全过程动态仿真的网络求解方法。 其特点是可以采取牛顿法或伪牛顿法实现，更适合于变步长技术的应用；
