Research On Optimization Of Reactive Power Compensation Of Wind Farm Based On Improved Genetic Algorithm

Wind power as a new energy, has become one of the important resources, technology is already quite mature, by the world attention, there was more and more researchers in this field of research. Now, the scale of wind power at home and abroad is gradually expanding,therefore, the uncertain factors in the power grid is increasing continuously. Wind farm grid will bring a lot of impact on the power grid, which is most affected by the wind power field, the regional power grid voltage quality. The main reason is that the grid connected to the regional power grid, the reactive power distribution, and further affect the voltage, the serious situation will cause the voltage collapse, which can not make up for the major losses. Due to the gradual increase of the installed capacity and the production scale of the wind farm, the power system has been seriously affected. Reactive power compensation measures to improve the power flow in the wind farm to reduce the power loss of the wind farm, and thus improve the voltage stability. At present, the most important research topic should be to take what kind of fast and efficient method to deal with the reactive power and voltage of the internal imbalance of wind power, and ultimately provide a high quality power resources to the power grid. However, due to the limitation of wind farm, there is no perfect and mature reactive power compensation optimization. And based on the predecessors’ research results and combining with the characteristics of wind farm itself,the wind farm reactive power compensation optimization to do the further research.First, this paper mainly introduces the current research status of wind farm reactive power compensation optimization, the basic situation of the wind farm are analyzed influence the distribution of the wind farm reactive power electrical equipment. Made in the power system containing wind farm wind generator, transformer, transmission line,reactive compensation device, and considering the load, the mathematical model of static characteristics. Based on PSASP software, constructs a model of basic flow calculation for power systems including wind farms. For further study of wind farm reactive power compensation optimization study provides data to support.Finally, combining the actual situation of xianju wind electric field. Set up the actual wind field each component and the corresponding mathematical model; and summary about the venue of the part and the corresponding mathematical model; modal of voltage stability analysis method and genetic algorithm improved combination method is applied to actual wind farm reactive power compensation and compensation capacity calculation and the results of practical application show this method has good optimal reactive power compensation effect.
