POWER CONDITIONER SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a power conditioner system for controlling charge and discharge of a storage battery connected to a power generator through an intermediate bus, by bus voltage control.SOLUTION: A power conditioner system 100 comprises: a photovoltaic power generation unit 110 composed of a solar cel 111 and DC/DC converter 112 of MPPT control; a storage battery unit 120 composed of a storage battery 121 and a voltage/current meter 122 for measuring an output voltage and an output current of the storage battery 121; an inverter 130 for converting a DC power output from the photovoltaic power generation unit 110 and the storage battery unit 120 to an AC power in synchronization with a power system 150; and a cooperation control device 140 for controlling the inverter 130. Generated power from the solar cell 111 is maximized by the DC/DC converter 112 and supplied to the intermediate bus. The cooperation control device 140 controls an output power amount of AC power of the inverter 130 on the basis of a measurement value of the voltage/current meter 122.
