【摘要】 分析力学是从能量的观点出发,应用数学中的分析法来求解力学问题,分析力学已经被应用于许多工程领域问题的求解。本文简要的介绍了分析力学中的 Lagrange 方程,并用 Lagrange 方程求解了电路中的 RLC 振荡问题；文中还讨论了将 Lagrange 方程应用于电力系统暂态分析中需要考虑的一些问题。更多还原

【Abstract】 Analytic mechanics use the analytical method in math to solve the mechanic problem with the viewpoint of system energy.Analytic mechanics had been applied to the solutions of engineering problems in many fields.This paper introduced the Lagrange equation of analytic mechanics in brief.And the Lagrange equation was applied to solve the problem of RLC oscillation circuit.Some problems,to which should be paid attention when Lagrange equation was applied to the power system transient stability analysis,were discussed in this paper.更多还原
