Control strategy of a 6 MVA Series Connected Synchronous Generator for wind power

A new proposal for a wind power system utilizes a variable speed generator, since it has a higher energy capturing and converting efficiency than a fixed-speed system. This paper describes a vector control strategy for a direct-driven Series Connected Synchronous Generator SCSG, which is connected to the power network through a controlled three phase rectifier and a PWM inverter. The generator side converter is controlled to obtain maximum power from the incident wind and the grid-side inverter maintains a constant DC-link voltage. Simulated results are given to illustrate the performance of the system.
