This paper first introduces the double-fed wind power generation systempsilas basic theory, and builds the mathematical model of the double-fed generator in the rotary coordinate system. In order to deal with the strong coupling problems in motor control field, the motor vector control technology is researched and the idea of dual-fed generator stator-flux-oriented vector control strategy is presented...
Wind power generation system is typical multi-variable, non-linear and too complex to build precise mathematical model. In order to capture maximum energy at certain wind speed range and regulate active and reactive power independently, adaptive fuzzy control based on stator flux-oriented vector control was adopted. The simulation program was written in C compile language and Matlab. The results show...
This paper presents the operational principles, design and transient analysis of a new three-phase 12/14-pole doubly salient electrical magnet (DSEM) generator for its application in direct-driven wind power generation. Design equations, finite element and dynamic analysis of the new generator are described. The 12/14-pole DSEM generator with constant self-inductance has lower voltage ripple compared...
Using rotor d-q model as a start point, this paper analyses the mathematical model for BDFM based on synchronous reference frame. And, based on characteristics of BDFM, a new type of power control system is designed by using the gap flux oriented vector transformation control technology. In order to no existing of the big power storage capacitors, the matrix converter is used to control windings of...
