POWER GENERATION SYSTEM AND INVERTER FOR FEEDING POWER INTO A THREE-PHASE GRID

摘要

PURPOSE: A power generation system and an inverter thereof are provided to supply power to a three-phase grid by connecting three AC terminals to a grid through a first and a second switching contact. CONSTITUTION: A power generation system comprises a relay arrangement. A relay arrangement separates an electric power system from a grid. The relay arrangement comprises at least three relays(R1~R3). Each relay has a control coil and two switching contacts. Two switching contacts are operated with the control coil. Three AC terminals are connected to the grid through two switching contacts.
