Photovoltaic grid connected inverter automatic testing platform

The utility model relates to a photovoltaic grid connected inverter automatic testing platform. The technical characteristics are that the platform includes two direct current simulation power supplies, two alternating current simulation power supplies, and a photovoltaic grid connected inverter automatic testing host computer. The testing host computer is connected with a direct current switch-gated cabinet via the two direct current simulation power supplies. The direct current switch-gated cabinet is connected with the direct current terminal of a photovoltaic grid connected inverter. The testing host computer is connected with an alternating current switch-gated cabinet via the two alternating current simulation power supplies. The alternating current switch-gated cabinet is connected with the alternating current terminal of the photovoltaic grid connected inverter via two simulation impedance networks. The testing host computer is connected with a power analyzer which is arranged on the two terminals of the photovoltaic grid connected inverter. The testing host computer is connected with a short circuit control cabinet via a simulation load. The two simulation impedance networks are connected with a data recorder. The photovoltaic grid connected inverter automatic testing platform has the advantages of comprehensive function, reasonable device configuration, convenient operation, and high measuring precision, thus having the important significance for the safety of public electrical network and user.
