Control System Design Of 20kW Vertical Axis Switched Reluctance Wind Generator And The Important Technologies Study

The developmental direction of the wind-generated electricity in the future will be transformed from concentration mode into distribution mode.Due to many factors such as huge noise,huge volume and structure,high cost complicated operation and so on,the horizontal-axis wind turbine is unsuitable for the distribution mode.While the vertical-axis wind turbine,owing to its small volume,suitable generating efficiency,lower cost,simpler operation and so on,is more appropriate for the requirement of new energy power generation.Switched Reluctance Generator(SRG abbr.)has many benefits itself such as high fault-tolerant rate,low cost,simple,which is quite suitable for the requirement of the vertical-axis wind turbine,making it become the main generator model for the distributional new energy power generation technology in the future.Aimed at the problems such as hing coupling,high non-linearity and so on existing in the operation Switched Reluctance Generator caused by the doubly salient,this paper lays special emphasis on analyzing electronic and mechanical energy transformation relationship in the operation of SRG.According to the designing requirement of SRG,this paper can identify its non-linearity through analyzing the data of flux linkage,angle and electric current by utilizing finite element analysis method.This paper takes the control system and control method in the operation of Switched Reluctance Generator as the research object,through analyzing the structure and function of the control system,improves the Maximum Power Point Tracking(MPPT abbr.)algorithm on the basis of the traditional feedback control of rotation speed.Namely,the algorithm,under the vague logical control,realizes the self-tuning of parameter system,and completes the Maximum Power Point Tracking control,thus accomplishing MPPT and enhancing the wind energy utilization.For the control system of 20 kw Switched Reluctance Generation,complete the power transformation circuit,driving the circuit and the rotor position detection,the hardware design for testing the circuit and the devices selection,and devise the systematic software.After that,conduct the experimental verification and the waveform test using the existing sample machine in the laboratory.
