Wind Power Primary System Design And Analysis In Some Coastal Islands Of Guangdong Province

This thesis describes the object for a wind farm inGuangdong coastal islands, through adesign process forwind farm electrical exposition, detailed description of thekey points in thedesign process, the designcharacteristic and technology of wind power a system.Feedback effect of actual operation by charged wind farm equipment operation3years time,the easy to wind farmdesign fault and the technical key point parts for analysis and theelaboration,focusing on the technology design of a corresponding electrical equipment related topoint.This paper is based on the project design process from coarse to fine is described, dividedinto the main contents of the following parts. The first describes the currentdevelopment ofinternational and domestic wind power,technology development achievements and trends,thewind farm electrical design related technical preparatorywork. Then described the fan selectionpart, mainly elaborates the selection of fan in the wind farm in the island, analyzes the generationprinciple and technologycharacteristics, slurry type wind turbine and the variable pitch windturbine doubly fed wind generator and permanent magnet generator, technical parameters andcharacteristics of VESTAS850/52, the wind the electricfan layout. Furthermore describes thecircuit design of35kV set. The technical characteristics of the cable and overhead line laying andcomparison.In view of the actualwind farm, described in detail the design and characteristics ofthe wind farm35kV collector circuit.Then the wind power system booster station a design andselection of main equipment.Design a system keybooster station35kV, design a system of110kV.Themain equipment parameters, including110kV GIS closedswitch equipment selection;50MVA step-up transformerequipment selection of110kV/35kV;35kV high voltage switchcabinet;35kV/690V fan supporting transformerand other equipment selection parameters.Continue todiscuss and analysis the impact of wind farm on the China Southern Power Grid110kV local area network analysis.For a wind farm operation review after3years, according tothe analysis of an electrical fault wind farm in the islandmay arise, focuses on the analysis ofequipment design principles of low voltage ride through capability andSVG wattless power compensation equipment.To providereference for the later the island wind farm design. By theend of this wind farm design an electrical system, the design content summary and promotion.Carried on the forecast and evaluation for the future of the island andoffshore wind powerconstruction.
