摘　　要：分析力学是从能量的观点出发,运用数学中的分析法来求解力学问题,分析力学已应用于许多工程问题的求解.在简要介绍分析力学中的Lagrange方程的基础上,用Lagrange方程来求解电路中的RLC振荡问题,并提出了将Lagrange方程应用于电力系统暂态分析中需要考虑的若干问题.Starting from the theories in system energy, analytic mechanics uses the analytical method in math to solve the mechanic problems. Analytic mechanics has been applied to the solutions of engineering problems in many fields.This paper introduces the Lagrange equation of analytic mechanics in brief, applying the lagrange equantion to solve the problem of RLC oscillation circuits. Some problems are put out and discussed, which should be paid attention to when Lagrange equation is applied to the power system transient stability analysis.
