At present, in the field of new energy sources, wind power generation is the fastest growing in the world. However, in our country, the current utilization rate of wind power has shown an unhealthy downward trend. According to statistics, in 2012, the average utilization hours of wind power equipment in China was 1890 hours, a decrease of 30 hours from 2011. On the one hand, wind turbines are "abandoning the wind"; on the other hand, the assembly of new machines is still undergoing large-scale development. In 2012, the installed capacity of new wind farms was 14.6 GW. According to the 2013 National Energy Working Conference Plan, this year's new wind power installed capacity will be 18 million kilowatts, is expected by the end of the year, China's total installed capacity of wind power will reach 78.83 million kilowatts. This means that if no measures are taken, the problem of "abandoning the wind" will be further aggravated. Shangpu consulting energy industry analysts believe that the bottleneck in the development of wind power or need to rely on improving delivery methods to solve. At present, China's wind power generation is mainly concentrated in areas with strong wind resource advantages such as the "Three Norths", but these areas have relatively limited energy consumption capacity, while at the same time, the non-stockpiling of electricity also causes huge energy in this area to fall into Uneven land embarrassing situation. Especially at night and in autumn and winter, when the wind resources are more abundant, the waste of resources of wind power becomes even more serious due to the decrease of demand and the failure of "heat-and-electricity" thermal power generation to give way to wind power. China's wind power construction is indeed in a very rapid state, but simply to blame the waste of wind resources is too fast anyway, the wind point is one-sided. In fact, the phenomenon of still requiring power rationing at the peak of electricity consumption in some areas shows that China's energy construction has not reached a serious overcapacity situation. However, as far as wind power is concerned, the problems of "re-sending light deliveries and failing to use electricity" in our power construction are still the key issues restricting the development of wind power. Therefore, to speed up the construction of UHV transmission channels over long distances or to solve the key problems of wind power applications. According to Shangpu Consulting's "2013-2017 China Wind Power Market Analysis and Investment Strategy Research Report", it is pointed out that the construction of new energy sources will be one of the industries in our country that are subject to the development of policy orientation. Wind energy as a renewable clean energy is the focus of new energy development in the world. Therefore, wind power development will maintain a rapid growth in the near future. However, how to transport excess wind power in the region to other regions to solve the problem of wind power utilization should be the focus of the entire industry. In fact, the transportation of wind power to the more developed eastern regions not only can make Western power useless, promote the economic prosperity of the western region, but also relieve the pressure of thermal power demand in the east within a certain range and also greatly improve the environment has an effect. 15A S20A military steel bar 30CrMnSiA Alloy Steel bar Military Steel Bar,military steel bar modification,15A S20A military steel bar,30CrMnSiA Alloy Steel bar SHANDONG LE REN SPECIAL STEEL CO., LTD. , https://www.sdcolddrawnsteelbar.com
