Abstract

This paper presents a new pitch control to improve the low-voltage ride-through (LVRT) capability of induction-generator-typed wind turbine generators (WTGs). On fault occurrence in the sub-transmission network, the proposed pitch control initiates the WTGs to achieve the fast power reduction. In this way, the over speed and over current of WTGs can be avoided. As the result, the WTGs can continue the connection to the network. In this paper, the effects of grid stiffness and static var compensator (SVC) location on the proposed pitch control are also studied by using the simulation model developed in MATLAB/Simulink with SimPowerSystems Toolbox. The simulation results show that the proposed pitch control system is effective under the different SVC location with different grid stiffness, and the performance of the pitch control system can be also improved by choosing the appropriate gain value according to the response time of pitch control.
