    Abstract: Analysis was made to the inverter power control principle in the photovoltaic power station. The inverter in photovoltaic station was tested and verified in possession of the reactive power (capacitive or inductive) two-way regulation capacity, which exceeded to the wide adjustable range of static var compensator full capacity operation, and could meet the requirements of the response time of static var generator (SVG) quick reactive power regulation, with the potential to act as the reactive power supply in photovoltaic power station and to support gridconnected voltage. The new type of reactive power supply functions of the photovoltaic inverter were developed to participate in the adjustment of regional power grid reactive voltage, which will produce great economic benefit.
    Key words: photovoltaic power station; inverter; phasing operation; reactive power supply
