摘要
在对电力系统数字仿真常用算法分析的基础上，本文将龙格－库塔法与梯形法相结合，提出了一种新的数字仿真方法：“龙－库－梯法”。对这种方法的误差进行了分析和修正，并引入补偿电阻，使得该算法大大提高了计算精度并很好地解决了数值振荡问题，因而可有效地用于超高压直流系统的数字仿真。
Based on analyzing several numerical method commonly used in digital simulation of power systems,this paper present a new digital simulation method-R-K-T method,which combines Runge-Kutta method with trapezoidal integeration one. The errors of this method are analyzed and the way of correction is worked out. A compensating resistance is introduced. As result the calculating errors are greatly reduced and the numerical oscillations efficiently eliminated.This method is expected to play an important role in HVDC system's digital simulations.
