초록
In this paper, a dynamic simulator based on an MG set was implemented for a scaled wind turbine model with a rated power of 40 W with an operating mechanism similar to that of a MW-class large wind turbine. A test bench constituting the simulator hardware was initially designed and manufactured by Carlo L. Bottasso's research team at the Technical University of Munich. In this study, part of the test bench was modified and redesigned, and a simulator capable of dynamic simulation was developed by applying a GUI for operation and monitoring, and a dynamic driving algorithm and turbine control algorithm. A DC motor is connected to the main shaft to emulate the rotor rotation. Also, in order to simulate the change in the rotor rotation speed according to the change in wind speed, motor speed control was performed using a numerical model of the wind turbine based on MATLAB Simulink. The generator part was directly applied to the MG set together with the nacelle part of the target wind turbine scale model. To verify the performance of the MG set-based dynamic simulator, it was compared with the existing MATLAB Simulink dynamic simulation model. The main performance data between the experimental results and the MATLAB Simulink-based dynamic simulation were compared, and an error within 1 % was confirmed. Using the MG set-based dynamic simulator built in this study, it was confirmed that it was possible to verify the performance of the wind turbine controller for dynamic wind in the laboratory before a wind tunnel test.
Abstract
In this paper, a dynamic simulator based on an MG set was implemented for a scaled wind turbine model with a rated power of 40 W with an operating mechanism similar to that of a MW-class large wind turbine. A test bench constituting the simulator hardware was initially designed and manufactured by Carlo L. Bottasso's research team at the Technical University of Munich. In this study, part of the test bench was modified and redesigned, and a simulator capable of dynamic simulation was developed by applying a GUI for operation and monitoring, and a dynamic driving algorithm and turbine control algorithm. A DC motor is connected to the main shaft to emulate the rotor rotation. Also, in order to simulate the change in the rotor rotation speed according to the change in wind speed, motor speed control was performed using a numerical model of the wind turbine based on MATLAB Simulink. The generator part was directly applied to the MG set together with the nacelle part of the target wind turbine scale model. To verify the performance of the MG set-based dynamic simulator, it was compared with the existing MATLAB Simulink dynamic simulation model. The main performance data between the experimental results and the MATLAB Simulink-based dynamic simulation were compared, and an error within 1 % was confirmed. Using the MG set-based dynamic simulator built in this study, it was confirmed that it was possible to verify the performance of the wind turbine controller for dynamic wind in the laboratory before a wind tunnel test.
