摘要
在基于Z源功率变换器的可再生能源并网发电系统拓扑结构分析的基础上,针对可再生能源系统的传导电磁干扰问题提出一种新的测量方法.利用该方法可以较为精确的测量可再生能源系统中的传导电磁干扰噪声,并设计相应的滤波器对于传导电磁干扰噪声进行抑制.并且,根据Z源功率变换器的特点,提出在直流侧加入电感或电容以稳定由于直流侧电能不稳定所带来的电磁干扰噪声问题.实验结果表明该方法较为有效.
In this paper,a new method is proposed to test the conducted electromagnetic interference(EMI) noise of renewable energy systems based on analysis the internal structure and measuring principle of Z-source inverter.A more accurate measurement of conducted EMI noise in new energy system can be provided by this method in order to design the appropriate filter for conducted EMI noise suppression.In addition,by adding capacitor and inductance in DC side can reduce the EMI noise as well.The result of experimental shows the method is effective.
