The Research Of Distribution Network Voltage Control Strategy And Application Of Voltage Regulator In Yangchun

With the development of economic, the distribution network load is constantly changing, so does the change of the power transmission and the load characteristics. Meanwhile, the development of clean energy under national advocacy background, in some areas, the number of small hydropower is also rapidly increasing, resulting in the distribution network voltage fluctuates seasonally too large, which has affected the daily life and production. Contradictions Over time, distribution network voltage problems have become increasingly prominent. In response to these obvious contradictions, the major domestic power companies have begun efforts to study was to investigate the factors affecting voltage distribution network, showing the influence of different factors on the grid in-depth analysis, and targeted some control strategies. At the same time, a variety of new technologies, new equipment also gradually increased.Based in current research results, and the present situation in Yangchun local distribution network, this paper analyzes the factors which affecting the distribution network voltage level, and put up the voltage control strategy. At the same time, we put up the configuration guidelines for regulators in the actual production depth discussion and summary for future distribution network planning and construction and to resolve the current-voltage distribution network to make recommendations.Thesis is mainly reflected in the following aspects:(1) Research and analysis several factors currently affecting the voltage distribution network, to discuss the principles and practice.(2) Study the different factors that affect the distribution network voltage given the appropriate way to deal with and control strategy.(3) Regulator technologies works on the analysis of different regulator technology were compared.(4) Of the regulator in the production practice application results were analyzed to give the regulator configuration guidelines and recommendations.(5) Based in Yangchun area distribution network for the status quo, load characteristics are given in the future planning and construction of distribution network gives guidance and advice for future in Yangchun Distribution Network voltage level to provide a stable basis for protection.
