中文摘要:

针对基于支持向量机的逆变电源故障诊断进行了研究。使用自行设计的变频电源模拟逆变器各种故障状态,分别采集了常态和各种故障状态下的电压信号,并进行波形和谐波分析。并在MATLAB中搭建了逆变电源的仿真电路用来验证实际电路实验。在电压波形和谐波分析的基础上,研究一种根据电压波形特征进行逆变电源故障诊断的方法,即采用支持向量机分类的方法对逆变器的故障状态进行分类。仿真实验和真实试验验证了基于支持向量机的逆变器故障诊断方法的有效性。

英文摘要:

In this paper, a method of fault diagnosis of inverter power supply device based on SVM it to be studied and a kind of variable frequency power supply device simulating various fault states of Inverter power supply is to be designed. The voltage waveform of Inverter power supply in the normal state and in various fault states was measured and analyzed. The simulation experiment in Simulink of MATLAB was set up to testify the actual experiment. On the foundation of the analyzing of the output waveform and quality of the power, a method about fault diagnosing is put forward, i.e. the fault states of Inverter are classified using a method of fault diagnosing based on SVM. At last, the SVM method is validated accurate through experimenting.
