摘要
以施耐德船舶综合电站为研究对象,对负载电机断条故障进行机理分析;建立数学模型,在负载电机出现断条故障的情况下对船舶综合电力系统进行仿真。通过FFT和小波分析等方法分析并提取负载早期故障下船舶电力系统发电机侧的特征,为进一步研究船舶发电机组神经动力系统容错控制提供有价值的数据信息。
With the Schneider ship power station as the target, the mathematical model of asynchronous load motors with the failure of rotor bar breaking is estabilishcd and the operation of the ship power system is simulated with such load failure by means of MATLAB software. The feature of this load failure at the generator side is extracted through FFT and wavelet analysis. This study will help to detect motor rotor bar failure in its early stage.
