This paper focuses on the design of Linear Quadratic Gaussian (LQG) controllers for variable-speed horizontal axis Wind Turbines (WTs). Those turbines use blades pitch angle and electromagnetic torque control variables to meet specified objectives for Full Load (FL) zone. The main control objectives are to reduce the structural dynamic loads and to regulate the power of the WT. The controllers are...
This dissertation is on control system for MW-class wind turbine. The basic control structure is on the performance of wind turbine and is a control system tracked power curve. To track the power curve, we discuss the control method for variable speed variable pitch that is used for torque control and pitch control. Furthermore, the MW-class wind turbine is a large structure and mechanical load created...
In this paper, a new type of wind turbine simulator (WTS) based on DSEM (doubly salient electro-magnetic machine) is proposed to simulate the steady-state and dynamic characteristics of a wind turbine in direct-driven DSEG (doubly salient electromagnetic generator) wind power generation system. A simple and effective torque control strategy is proposed to realize torque closed-loop control of DSEM...
In the wind energy conversion system, the wind turbine captures the wind energy. Then the generator changes it to the electrical power. So the characteristic of the wind turbine is very important. For some laboratories that donpsilat have the practical wind turbine, it is very convenience to use the wind turbine simulator instead of the real wind turbine. The paper introduces the structure and characteristic...
