Abstract


The reactive power compensation plays a huge role on safe and reliableoperation of power grid and the improvement of power quality. Therefore it has moreand more important practical significance to realize real-time, fast and exactcompensation of reactive power. Large-scale smart grid construction has beengaining momentum with the changing of the morphology of the grid caused bypower electronics. Static var generator reactive compensation has become animportant part of the present smart grid as a new dynamic device. In order toovercome the inherent flaw of current static var generator itself，the dissertationoptimize the static reactive compensation device，proposed and designed static vargenerator based on Z-Source network.By reading a large number of outstanding domestic and foreign literature,understanding the purpose and significance of reactive power compensation,observing the development trend of reactive power compensation device and thecurrent research status of static reactive power generator, the advantage and theproblem which can be solved have been work out by the static var generator based onZ-Source network. The three-phase static var generator based on Z-source network isdesigned by choosing the direct current control strategy and dq reactive currentdetection method. Through the calculation the key parameters of Z-source networkand the load parameters of the system are determined, and the detection modulewhich matching the system is selected. Simulation model of SVG based Z-sourcenetwork is built in Simplorer9.0, in response to the presence of Z-source network onthe impact of compensation effect of static var generator. Simulation results showthat static var generator based on the Z-source network has lower requirements ofcapacitance and voltage of the inverter circuit on DC-side and better compensationeffect of power grids and wider range of compensation, and it proves the accuracy of the design. In this dissertation which is on the basic of theoretical research andexperimental simulation, the hardware and software configuration of the entiresystem is designed, and the experimental platform for static var generator based onthe Z-source network for experimental study is built. In the experiment, thewaveforms of voltage and current are in the same phase, and the compensation effectis good. Results show that static var generator based on the Z-source network offersreal-time reactive power compensation, enhances the reliability of static vargenerator, and further proofs of the validity and feasibility of this design.
