摘要
变频驱动对电网产生了严重的谐波污染,消除谐波影响已成为电力推进船舶研制的关键。在建立小型电力推进系统谐波分析的数学模型基础上,对无源滤波装置的拓扑结构进行改进,并采用改进遗传算法对该无源滤波器参数优化。根据优化参数设计所提出拓扑结构的无源滤波装置,应用MATLAB7.0软件对电力推进系统进行仿真,仿真结果证明该拓扑结构和参数优化方法的正确性,达到谐波抑制的良好效果。
With the rapid development of ship electric propulsion system based on the technologies of variable velocity and variable frequency,the application of electric propulsion is getting more popular.However,variable frequency driver may produce serious harmonic contamination of power system and the harmonic suppression becomes a key of electric propulsive ship development.Based on a mathematical model of harmonic analysis of ship electric propulsion system,the topology structure of passive power filter is improved and parameters of the filter are optimized with improved genetic algorithm.Electric propulsion system with the filter designed by optimized parameters is simulated with MATALAB7.0,it is validated by simulation that the topology structure of passive power filter and the improved genetic algorithm are correct and effective in harmonic suppression.
