Abstract: With increased wind power penetration in modern power systems, wind turbine generators (WTG) are expected to provide the active power control (APC) for tracking a desired power reference from system or wind farm operators.
Therefore, the driving force in the blades and the load on the entire structure of the turbine should be decreased. The most basic, robust and cheapest method for power control is stall control (passive control). The blades are fixed firmly to the hubs, and the angle of wind strike of the wing is fix.
The entire system consisting of wind turbine, PMSG, MC, ac link load and controller has been mathematically modelled. A simple VOC scheme has been developed and the power regulation has been achieved using conventional gain scheduled PI controllers and NN-PIs. Detailed simulation studies have been presented.
The control system may also stop the wind turbine, reduce structural load, and maximize the power generation by using the active wind turbine management, which costs the life spans for the mechanical components. The control system should ensure the maximum efficiency of wind power is extracted by the turbine at low wind speeds.
Variables such as rotor speed, output torque, wind speed, pitch angle and terminal voltage or a combination of these can be used as the input variable to the controller. ANN is suitable for WT control in situations where the aim is optimization of power at wind speeds above the rated wind speed.
The rotor of the wind turbine is managed using a pitch control mechanism. The dynamics of the converter are controlled using synchronous reference control. In the power limitation consideration, the wind turbine speed is variable only used together with the fast pitch mechanisms.
