摘　　要：基于数值振荡是电力系统数字仿真领域中一个长期困扰的问题，研究了电力系统仿真中各种数值振荡的产生机理，并提出相应的对策．分析了插值算法对数值积分精度的影响，提出了电力系统仿真中插值算法的选择原则．Based on the deeply investigation of their mechanism, the countermeasures of various types of numerical oscillation in power system digital simulation were presented. The effects of interpolation on the simulation accuracy were studied and the principles of choosing interpolation methods in system simulation were derived. The results have basically solve the numerical oscillation problems of power system digital simulation.
