摘要

介绍了太阳能光伏发电系统同步到三相四线电网的控制问题。性能在电网中断模式下进行验证，太阳能日照减少和负载不平衡。当电网存在时，电力传输伴随着无功功率和中性电流的补偿。电网电流的总谐波失真(THD)符合IEEE-519标准，从而保证了令人满意的性能，同时减少了配电网的损耗。此外，在电网中断或孤岛运行模式下，太阳能光伏阵列通过电压控制器将电力输送到本地负载。仿真结果验证了该方法的有效性，并观察了弱电网条件下以及电网中断条件下的系统行为。

Synchronization of Solar PV System to Grid with Enhanced Power Quality

The control of solar photovoltaic (PV) system synchronized to three-phase four-wire grid is presented here. Performance is validated during grid outage mode, solar insolation reduction and unbalancing of loads. When the grid is present, power transfer occurs along with compensation of reactive power and neutral current. The total harmonic distortion (THD) of the grid current is in compliance with the IEEE-519 standard thereby guaranteeing satisfactory performance along-with reduction in losses of the distribution network. Moreover, during the grid outage or islanded mode of operation, the power is delivered from solar PV array to the local loads by a voltage controller. The performance is validated though simulation results and the system behaviour is observed for weak grid conditions along with grid outage conditions.
