摘要
光伏并网发电是太阳能资源利用的重要方式,具有无功补偿功能的光伏并网发电系统对改善供电质量,提高发电效率有重要意义。提出一种将逆变器和静止无功发生器相结合的三相光伏并网发电控制装置。该装置能够实时检测光伏阵列输出电压和电流、电网电压和负载电流,具有过压、欠压、过流、断相、短路等保护功能。
The grid-connected PV is an important way to the use of solar resource. The device integrated reactive power compensation, which is necessary to improve the quality of power supply and efficiency. An integrated control device of three-phase PV inverter and SVG was introduced. The device can detect the PV array output volt- age and current, the grid voltage and load current in real time. It also has function for protection such as over volt- age, under voltage, over current, phase failure and short circuit.
