摘要
为提高舰船电力系统的稳定性,给出了应用RHR算法计算两机并联舰船电力系统Lyapunov指数的推导过程,并根据Lyapunov指数的性质分析系统的动力学行为。结果表明:当系统中存在的周期扰动满足一定条件时,系统进入混沌振荡,应用RHR算法定量得出系统发生混沌时扰动幅值和扰动频率的取值范围,同时RHR算法的收敛速度快,为抑制或消除舰船电力系统中的混沌提供了数值计算依据。
In order to enhance stability of ship power system, RHR algorithm was applied to computed Lyapunov exponent of two parallel nonlinear mathematical model of ship power system, and system＇s dynamic behaviors were analyzed according to the nature of Lyapunov exponents. Simulation resuhs indicate that chaotic oscillation occurs in ship power system under certain periodic perturbation, and RHR algorithm can acquire value range of perturbation magnitude and frequency when chaotic oscillation appear in system with fast convengence speed, that can provide computation basis to suppress or eliminate chaos in ship power system.
