Mppt For Variable Generation Voltage Converter Drives Swithced Reluctance Wind Power Generation System

Applied generator of wind power system, the control technology is quite perfect.Currently mainstream generators include asynchronous generator, the doubly-fedgenerator and permanent magnet synchronous motor in the field of wind power. As anew type of special motor, switched reluctance motor has been deeply studied onlyless than twenty years. Compared with other generators, it has many features such assturdy structure, small moment of inertia, multi-way control modes and wide speedrange, which have been fully reflected in the wind power generation system and getbroad application prospects in the field of wind power as well as a high practicalvalue.First of all, this article briefly describes the switched reluctance wind powersystem, combined with existing data for maximum power tracking. It studies andcompares the three common MPPT methods.Secondly, this article describes the methods and theoretical basis of experimentalplatform motor parameters, and makes analysis on the main circuit of experimentalplatform, control circuit, driver circuit, position detection, and signal detection circuit.The main work of this article is to put forward to the variable power circuit whichcan efficiently capture wind energy in low wind speed after combined with the typicalasymmetrical bridge circuit as soon as described the works of switched reluctancemotor, It solves the problem that the motor peed is not high when the wind speed islow and it is difficult to guarantee excitation after the current continues by controllingthe power converter and adjusting the power generation voltage, so this methodimproves the efficiency of energy conversion.This article uses MATLAB/M file to simulate, mainly studies four-phase8/6switched reluctance motor which is controlled by DSP28335, simulating wind turbinewith induction motor to complete the comparative analysis on the performance withangle position control method between the traditional asymmetrical bridge circuit andvariable power generation circuit, and then verifies the correctness of the controlstrategy.
