30 kW太阳能并网发电系统的应用与运行

The Analysis to the Application and Operation of 30 kW Grid-connected Solar PV System

文中介绍了在蚌埠投运的总峰瓦值为30 kW的太阳能并网交流发电系统,该系统属于逆潮流系统,并网于110 kV变电站的站用电低压母线,剩余电量向电网逆潮流送入。系统采用单晶硅太阳能电池组件,转换效率达到16%以上;运用电流控制型PWM有源逆变技术、MPPT最大功率跟踪技术和高效隔离变压器,并网保护功能齐全,输出谐波抑制效果优异。该系统投运行情况良好。

The 30 kW grid-connected solar PV system,which is operating in the city of Bengbu,is the exchange against the tide systems. It＇s network stations is in the 110 kV substation＇s low-voltage power bus,and the dump energy sends in against the tide to the power grid. It uses single ＇crystalline silicon solar cell modules,that it＇s conversion efficiency achieves above 16%. It adopts current-controlled PWM inverter technology active,MPPT maximum power tracking techniques and the highly effective isolation transformer. It＇s network protection function is complete,and its output harmonic suppression effect is outstanding.
