| 摘 要： | 为分析船舶电力系统双机并联运行的可靠性,建立了船舶电力系统的双机并联三维自治系统模型.运用系统分岔分析、相图分析、Lyapunov指数和Lyapunov维计算,对系统进行了分形与混沌振荡分析研究.分析结果表明发电机双机并联系统混沌振荡现象的存在,得出当系统中的发电机之间存在一定的功率传递,并受到一定幅值的扰动干扰时将会发生混沌振荡现象的结论.船舶电力系统的混沌振荡是一种不稳定运行状态,这种不稳定运行状态往往发生在系统轻载工况下,需要进行预防.

| Abstract: | In order to analyze the operation reliability of a shipboard power system with two generators connected in parallel,a three-dimensional autonomous system model was established.Research on fractal and chaotic oscillation in the system was made using bifurcation analysis,phase space analysis,Lyapunov exponentials,and dimensional calculations.Results of the analysis indicate that chaotic oscillation phenomena in the generators result from chaotic oscillations of shipboard power systems.Unstable chaotic oscillations occur when power transfers between two generators experiencing amplitude disturbances under light load conditions.This type of system operation should be avoided. |
