柴油发电机组并联运行的混沌振荡分析
The analysis of chaos oscillation for a diesel-generator set on a parallel connection
摘要
Abstract
Several diesel-generator sets usually operate on a parallel connection in a ship power system. An oscillation phenomenon of a power system which is acyclic, random, and gusty or paroxysmal will occur during light load working conditions; it has the feature of chaos processing, which can result in ship power system sectionalizing when it is serious. Safety operation of the ship power network will be threatened. In order to analyze the chaos phenomenon of the ship power system, a nonlinear mathematical model of two diesel-generator sets on a parallel connection was built in this paper, which reflected the variation law of each varible in two diesel-generator sets, describing the relationship of interaction and mutual influence between the two sets. The light load working condition of the two diesel-generator sets on a parallel connection in the ship power station was analyzed by using the Lyapunov index method, which proved the presence of the chaos phenomenon. The conclusion was drawn that the ultimate reason for producing the chaos phenomenon is the nonlinear feature of the ship power system and power transfer between two diesel-generator sets. The chaos phenomenon is a transition state between the stability and instability states, which must be prevented so as to ensure the stability of system.关键词
