Abstract


Reactive role to play to improve power factor compensation in the power supply system to reduce the power supply equipment and power transmission line losses , improve voltage quality . From the current situation of China's economic development , electricity supply and demand is gradually deepened , and customers access to the distribution system of power quality requirements are also rising , more and more reflect rational optimization of reactive power compensation , the importance of the configuration . Reactive power compensation device and the capacity for rational choice , can be done to minimize network losses , improve the quality of power supply ; contrary, it may cause the power supply system voltage fluctuations , harmonics increases and many other issues . Distribution network reactive power compensation principle , to illustrate the significance of reactive power compensation , reactive power compensation of existing distribution network to compensate for the status quo to do a systematic analysis than clear reactive should have the function of the key components of the compensation equipment . Reactive power compensation status and electricity load characteristics of urban and rural distribution network Qinglong Manchu Autonomous County , Qinglong Manchu Autonomous County of urban and rural distribution network reactive compensation technology transformation programs and reactive power compensation device parameters using based on the the Java2 platform of J2EE architecture development background for distribution transformers and reactive power compensation device management software , to facilitate the management and maintenance of the equipment . Typical reactive power compensation transform instance through the area with different characteristics , further elaborated the actual effect of the transformation of reactive power compensation in Qinglong Manchu Autonomous County of urban and rural areas with grid power factor , line loss and equipment management , and validation of the proposed scheme feasibility. Reactive power compensation is an important part of the distribution network construction and transformation , reasonable choice of reactive power compensation point , reasonable compensation determined , able to effectively maintain the voltage level of the distribution network , improve voltage stability , reduce network losses , improve voltage a small investment, high - return program , directly determine and influence the economic efficiency of the power supply enterprise , planning and implementation of reactive power compensation is imperative .
