The Research on Direct Drive Permanent Magnet Synchronous Wind Generator Vector Control

Abstract:

Direct drive permanent magnet synchronous generator have the advantages of direct drive, simple structure, high efficiency and so on, in which make it become one of mainstream models within MW wind turbine presently. Making the direct drive permanent magnet wind power generation system as the main research object, based on the principle of the operating characteristics of direct drive permanent magnet synchronous wind generator ( DDPMG ), establish mathematical model of the whole system including wind turbine, direct drive permanent magnet synchronous generator and machine side converter, applying the method of stator flux orientation to make the study of vector control strategy, to build the simulation model of direct drive permanent magnet synchronous generator system with Matlab to simulate the operation of generator when wind speed changes by step, the results validate the reasonableness of the model and the correctness and feasibility of the control strategy.
