Study On The Vessel Type Wind Power Generation Converter

Now the price of conventional energy sources step up, and because the extensiveuse of conventional energy sources, brings the environment problem more and moreserious. New energy development and application has been a global common strategy,and has produced very good effect. The use of wind power at the present stage is thefastest-growing segment of the new energy. At present the main application of windpower, is use wind power to generate power. The wind power generator has beendeveloped toward two directions: large grid fan, mainly used in wind farms in gridgeneration; Small wind generators, mainly used for a single family or small rangeelectric network.This task mainly research for the small wind generators. Developed the trackingand yaw system can be used for small wind generators, this system can improve theefficiency of the small fan; at the same time, this system structure is simple, thedevice consumption is less. This paper presents the design and circuit structure of thispart, and the used procedures. Due to the special structure of the wind generator, thevoltage waveform is special. The rectifier circuit part using uncontrolled rectifiercapacitance filter, can achieve good effect. In this paper, the selection of devices andchoose the basis for the device.Inverter part is the core part of fan unit, also is the most important part of thistask. The current application inverter because of circuit structure reasons, often appearall sorts of problems, the reliability of the inverter is not high. Application of a newtype of inverter circuits-Z source inverter circuits in this paper. This paper presents theprinciple of the circuit, and the different circuit transformation at different states.Through the cooperation of modulation M and zero vector time T0complexes, thecircuit can realize the buck-boost function. This paper gives the Z source invertercircuit structure, and device selection. Buck-boost function of the circuit was verified.Due to the special structure of the circuit, the inverter circuit can improve thereliability of the inverter.The control signal of the inverter part, can be produced by a singlemicrocomputer or integrated circuit. This paper is use the simulation method, thiscircuit is simple and strong interference immunity. In this paper the realization ofcontrol signals of the overall circuit diagram was given, and the circuit of generate for each signal circuit.
