摘　　要：电力系统全过程动态仿真是将机电暂态和中长期动态过程有机地统一起来进行的仿真计算。通过对电力系统长过程动态稳定特性的模拟分析,了解系统中长期失稳的动态特性机理,对电力系统规划设计以及避免可能发生的大停电事故等有重要意义。对电力系统全过程仿真中遇到的主要问题,包括刚性系统求解特点、典型数值积分算法的优缺点、非线性代数方程迭代解法等做了阐述。最后,对目前国内外主流全过程动态稳定仿真软件所应用的数值算法做了总结。The full dynamic simulation combines electromechanical transient process and mid-long term dynamic process.Through simulation of the power system dynamic characteristics,to understand the mid-long instability mechanisms,it has great significance to power system plan and to avoid blackout.The main problems in the power system full dynamic simulation are introduced in the paper,including mid-long term solution characteristics of rigid system,advantages and disadvantages of typical numerical integration algorithms,iterative method for solving nonlinear algebraic equations.Finally,the character of the algorithms used in the mainstream simulation tools for full dynamic simulation are summarized.
