摘　　要：针对光伏发电系统非接触并网供电过程中存在的电能信号输出不稳定的问题,提出了非接触并网供电自动控制方法。首先在光伏发电系统以及并网供电线路上安装相应的硬件设备,包括控制器、逆变器以及驱动设备等,其次采用非接触并网的方式形成供电传输链路,利用安装的硬件设备自动监测供电系统中的电流信号与电压信号,以监测结果为基础,分别从并网电流平衡与最大供电功率两个方面,实现了对光伏发电系统并网供电的自动控制。为检测设计控制方法的性能设计了实验,实验测试结果表明:光伏发电系统非接触并网供电自动控制方法可以缩小供电电流与电压的浮动范围。Based on the problem of power signal output instability in the process of contactless grid connected power supply of photovoltaic power generation system,an automatic control method of contactless grid connected power supply is proposed. Firstly,the corresponding hardware equipment,including controller,inverter and driving equipment,is installed in the photovoltaic power generation system and grid connected power supply line. Secondly,the power supply transmission link is formed by non-contact grid connected way. The current signal and voltage signal in the power supply system are automatically monitored by the installed hardware equipment. Based on the monitoring results,the current balance and voltage balance of grid connected power supply are respectively in the two aspects of maximum power supply. The automatic control of grid connected power supply of photovoltaic power generation system is realized. In order to test the performance of the design control method,the experimental results show that the non-contact grid connected power supply automatic control method of photovoltaic power generation system can reduce the floating range of supply current and voltage.
