资料介绍

由于舰船环境相对复杂,传统的在线绝缘监测手段大多无法良好适用于舰船电力系统中变频调速电机,这个问题严重影响了变频调速电机的可靠性,从而制约了变频调速电机在现有舰船上的应用。本文针对变频调速电机,基于双频注入信号法,设计了一种在线测定变频调速电机绝缘电阻及对地电容的方法,并对其预先调试做出了分析。通过Matlab对该方法的仿真,验证了此方法的正确性。

Because of the complex environment of the ship,most of the traditional online insulation monitoring methods cannot be well applied to variable frequency speed-controlling electric motors in ship power s problem seriously affects the reliability of the frequency conversion motor,thus the application of VVVF motor on the ships is this paper,a method for on-line measurement of insulation resistance and ground capacitance of variable frequency motor is designed based on dual-frequency injection signal method,and its pre-debugging is correctness of the method is verified by the simulation of MATLAB.
