Abstract

A three-phase photovoltaic interconnected device having both reaction and harmonic compensation function, and belongs to the field of multi-functional photovoltaic interconnected device technology. The characteristic is: the main power circuit of this device is composed of the photovoltaic array, the interconnected inverter and interconnected filter sensor. The structure of the inverter has many kinds of patterns, such as the two level structure, the three level structure, the three-phase generatrix capacitance separated chain structure with transformation, the three-phase union capacitance chain structure with transformation and the chain structure without transformation. This device can emit the power to the electric net, and can in time compensate the reaction and harmonic wave of the current in the net. This invention increases the utilization ratio of the solar battery board of photovoltaic electricity generation, and meanwhile it solves the problem of the working method of the photovoltaic system in the bad lighting conditions, that is, the system will not be left unused and compensate the harmonic wave and reaction of the electric net.
