提出一种基于网式链表-双层结构的时域仿真算法,外层是显式算法,内层是隐式梯形算法。显式算法既可单独调用,又可实现隐式算法的预测功能。网式链表结构是在十字链表稀疏存储格式上发展的一种逻辑框架,该结构的引入使得内层隐式计算可以灵活有效地处理各种动态元件与控制器接口、微分代数方程系统微分与代数部分接口,并可以任意组装、拼接基于模块化设计的微分代数系统全雅可比矩阵。最后,给出基于网式链表-双层结构仿真算法的工程软件实现方案。
A new union structure for time-domain simulation of power system is presented, which is realized via double layer algorithm with build-in net-form chain. The inner layer is designed for implicit method whereas the outer one is designed for explicit method. The explicit method can be used as a predictor for implicit method or as an independent algorithm. Net-form chain is a logical structure developed from orthogonal list technology for sparse storage. The interface between dynamic devices and their controls can be flexibly designed, so as the interface between dynamic devices and network. The blocking Jacobian matrix can be assembled expediently. The realization scheme for simulation software design using the new algorithm is given.
