This paper reports design of a start-up controller for a 100 kW wind electrical power plant. The plant is designed to be able to work either in isolated or grid-connected circumstances. This paper aims at designing a controller for start-up and operation of the plant in isolated mode. The controller has been designed to provide excitation voltage during the start-up and to maximize energy conversion during operation as well as to maintain the DC link voltage be at desired value. Controller design uses vector control and hysteresis PWM approaches. From computer simulation results it is concluded that the plant can start-up at cut in wind speed of 2.5m/sec by maintaining DC link voltage at 96 V, and it changes over from motoring mode to generating mode in 15.5 seconds giving start-up electrical power of 761 Watt. Moreover, the controller can make the generator produce electrical power of 23.48 kW and 111.58 kW for average wind speed of 7 m/s and rated wind speed of 12m/s, respectively.
