摘  要:
For wind power generation research in lab,it's valuable to build wind turbine simulation system.Based on energy conversion principle of small wind turbine,the mathematic model of the operation characteristics of wind turbine and its power&torque characteristics are analyzed.The feasibility of simulation of wind turbine based on DC motor is discussed.Based on mathematical model,torque control and speed control methods of simulation of wind turbine based on DC motor are analyzed in detail.Then simulation model and experimental system are built to test and verify theoretical analysis.The results indicate that the speed control method adopting double closed-loop regulation has good precision,quick dynamic response and widen operation range,which can be used in the research of wind power generation technology in laboratory.
