This paper introduces the design of 800kW doubly-fed induction machine (DFIM) system, which include DFIM system's structure, vector control strategy and the operation of converter. Three-phase, half-wave cycloconverter and stator flux-orientated vector control are adopted to achieve motor speed control and permit leading power factor (PF) operation on the stator side. There is no inter-group reactor...
The design feature and performance analysis based on circuit-field coupled finite element analysis of large scale direct-driven permanent magnet (PM) generators are introduced. Some experimental results are presented. The simulation and experimental results of a 1.5MW PM wind generator show that the pole-slot number combination has an important impact on the machine properties, and the optimization...
Due to the complexity of structure as well electromagnetic coupling, accurate calculation of self and mutual inductances of stator and rotor windings for doubly fed brushless machine (DFBM) with cage rotor is difficult which is likely to lead to inaccuracy in performance analysis. In this paper, a method of parameter calculation and performance simulation based on combined magnetic field analysis...
