Electric power equipment and new energy: compensation of wattless power market is up to 7000000000
Reactive compensation is not a necessary device for power system. Active power in power system and has no power to exist at the same time, the reactive power isn't useless power, which is the necessary condition of electrical equipment can work. Therefore, through the installation of shunt capacitor device in power system are needed for wattless power compensation, to achieve the improvement of voltage quality, reduce line losses, line and transformer capacity, reduce the cost of electricity.
Energy-saving emission reduction and power quality requirements increase will continue to promote the wattless power compensation demand. The development of power industry in our country has experienced no technology introduction, digestion and absorption of import substitution process, along with the electric power supervision departments on the power factor requirements increase and the enterprise to realize the importance of power quality improvement, wattless power compensation equipment in the domestic market demand starting around 2004 outbreak. Looking to the future, we believe that energy-saving emission reduction pressure increases, the policy implementation efforts, new energy equipment manufacturing industry upgrade and increase the requirement of power quality improvement will be no reactive compensation equipment demand driving force.

SVG will gradually replace SVC. From the point of view of product development, compensation of wattless power has gone through the condenser, the fixed compensation capacitor, SVC, SVG stage. SVG in the speed of response, filtering characteristics, operating loss and floor area is better than that of SVC, but the more expensive price is the main obstacle in previous years. In the past two years through technical improvement and the scale of production, in the small volume products and wind power and other special areas, SVG price is close to the SVC, gradually have the alternative of SVC price advantage, the future development of SVG is worth looking forward to.
In the next few years wattless compensation capacity of the market could reach 70~140 billion yuan. We calculate the wattless power compensation capacity of the market, in the low allocation ratio under the assumption of 2012~2015 years, or up to 7000000000 yuan; in the high allocation ratio under the assumption of 2012~2015 years, or up to 14000000000 yuan. Application of power sector will gradually occupy a larger proportion of.容来自:中电易展网
