Abstract

The present invention provides pre-determined reactive power to asynchronous generator of a wind turbine, through a feedback controlled inverter by eliminating the usage of capacitor banks and is installable in remote places where grid (G) power is not available. A novel control system with 3 phase inverter setup using power transistors or IGBT's as switching elements provides reactive power for excitation to maintain sustained generation. Negative slip is controlled based on the reference DC voltage generated through the freewheeling diodes of the IGBT's. In grid (G) connected system, better efficiency is achieved by pumping reactive power from the 3 phase inverter in synchronization with power grid (G) line frequency. The system can also be used in non-grid (G) connected wind turbines to provide electrical power to local loads and in grid (G) connected systems the generated power from the Wind Turbine is exported fully/partially after usage for local loads.
