| 摘 要： | 提出了一种同时实现无功补偿的光伏并网发电技术,通过对逆变器输出电压的幅值和相位进行调节,改变逆变器输出电流的有功和无功分量.在白天,光伏发电系统能同时进行有功功率输出和电网无功功率补偿;在光照强度很低或夜晚光伏电池不能发电时,仍然可以利用该系统进行无功功率补偿,提高了系统的利用率.仿真结果验证了该技术的可行性.

| Abstract: | A new technique for grid connected photovoltaic (PV) system that can realize the reactive power compensation (RPC) was presented. The active current and reactive current of the inverter are regulated with changing the amplitude and the phase of the output voltage of the inverter. The active power output and the RPC of the system are realized synchronously at daylight. When the insolation is weak or the PV modules are left unused at night, however, the RPC can still be used, which improves the efficiency of the system. The simulation results validate the feasibility of the technique. |
