06 六 10 National Grid announced seven wind power base and network programs
As the wind power to implement the main subject of the past year, National Grid has problems because of wind power to withstand the pressure from all sides.
May 28, at the national power grid wind power development forum, the national grid to local governments, power plants and wind power turbines equipment manufacturers are invited at the meeting, also requested the four major air TV province of Jilin, Inner Mongolia, Hebei and four provinces of Jiangsu Development and Reform Commission officials to give priority to talk on the planning, raised questions and requests.
“Our purpose is to make local wind power development planning and network planning for better convergence.” Shu Yinbiao vice president of State Grid said. In recent years, the rapid development of wind power from central to local wind power development planning is also progressively expanded, leading to “wind power sometimes do not know where the building.”
Up to now, the national grid access and supporting wind power generators transmission project investment of nearly 40 billion yuan, total access to 16 million kilowatts of wind power, but some still failed to grid wind.
Reporter was also informed that the National Energy Board is organizing the recent launch wind power and market access elimination on research work, also headed a team to Denmark, Spain and other countries study tour of Europe wind power consumptive experience.
However, the greatest impact of wind generator development plan, and no doubt the state of the seven wind power base of 10 million kilowatts. Recently, the National Grid has completed seven wind power base sent the planning, Absorptive capacity and the consumptive market analysis and research.
May 28, National Grid announced a seven wind power base in 2015 and 2020 access systems and transmission planning.
Seven base and network planning according to the national wind power development plan, Hamilton, Jiuquan, Hebei, Jilin, Jiangsu coast, Mongolian East, West Inner Mongolia 7 10 million kilowatts of wind power base will be built by 2020, planning to build 58.08 million kilowatts by 2015 , 2020, 90.17 million kilowatts, accounting for the national total installed capacity of wind power around 60%.
As a large wind power capacity, the base is branded as “Land of the Three Gorges” title. However, with a total installed capacity does not match, most of the wind power base in northwestern China, the local electricity load is low, its assimilative capacity of weak consumption. Above, determine most of the power consumption required to accept a greater range.
National Grid proposed “building large bases into the bulk power system”, and from near and far stages of overall consumption Gopinath Road, and from 2009, organized by the NARL State Grid, the provincial company and the electricity network design hospital on the analysis of these issues.
According to researchers at the National Grid, West Inner Mongolia Wind Power needs in West Inner Mongolia and the “three Chinese” Power (North China Power Grid, Central China Power Grid and East China Power Grid) Absorptive; Mongolia wind power grid in the Northeast and East China Power Grid Absorptive; Hamilton wind power in Northwest Power Grid and Central China, North China Power Grid Absorptive; Jiuquan wind power in the Northwest China Power Grid and the consumer is satisfied; Hebei Power “three Chinese” Power consumption is satisfied; and Jilin and Jiangsu Power consumption in the region is satisfied.
However, it was estimated that in 2015, seven provinces and consumer of wind power base of 37.08 million kilowatts inclusive, cross-Absorptive 2100 kilowatts; and 2020, the provincial Absorptive 48.54 million kilowatts, cross-Absorptive then rose sharply to 41.63 million kilowatts, which require a large number of long-distance transmission line construction can be achieved.
At the meeting, officials in Inner Mongolia Development and Reform Commission requires National Grid to speed up wind power in Inner Mongolia three outgoing channel building in order to meet long-term 38 million kilowatts installed capacity in Inner Mongolia formed a large capacity.
Shu Yinbiao said recently Tianjin-Tangshan power grid operation by optimizing the way, the net output of non-heating unit to run down to the limit so low in West Inner Mongolia Power Grid Transmission time from 1.95 million kilowatts of capacity to 260 million kilowatts, to help the western Inner Mongolia Absorptive wind power.
According to the latest transmission program, through the West Inner Mongolia region Chagan nur, gray Teng Liang, mulberry root Dallery 500 kV pooling station 10.1 million kilowatts of wind power, 3.9 million kilowatts by Ximeng to DC for delivery in Jiangsu, 6.2 million kilowatts by special High exchange channel sent. Meng Lu East, mainly through open, beads, r., poplar ditch gate, Matsuyama 500 kV pooling station for delivery of wind power. 2017 Construction of Chifeng – Jiangsu ± 800 kV DC project, the line length of 1700 km.
Delivery channels for high investment cost, renewable energy National Energy Board, Deputy Director Shi Lishan that the outgoing channel in the building, we should change the idea of full Shougou, there should be some give up wind plan, to transmission line more economical.
He further said that the current wind turbine generators installed capacity of 1 million, most of the time to contribute only 400 000 -50 million kilowatts, while the high-load periods occur only a few times a year, so if the maximum load to design transmission lines, is clearly very economic .
Consumers satisfied with the plan and the corresponding transmission capacity is peaking. As the wind is unstable, long-distance power transmission and thermal power or hydropower be bundled. National Grid plans to the wind electric coal rich area, combined with Wind and Fire outgoing Binding mode; and can not be tied to the area through the construction of pumped-storage peaking station to resolve the issue.
Specific objective is to operate the national grid by 2015, district-scale pumped storage power station need to reach 21 million kilowatts, 41 million kilowatts by 2020.
State Electricity Regulatory Commission regulation of the Department of Renyao Hong transmission have pointed out that the cost of pumped storage costs or large, if the three north wind power and hydropower can complement each other intermodulation Southwest will be able to achieve a wider range of consumptive wind energy, but also FM peak load regulation can enhance the ability.
Shu Yinbiao excluding disorderly development, said the proposed national grid wind power base in the seven transmission planning into the national energy development strategy and “12 5″ Power Planning in order to achieve elimination on wind power planning implementation.
In fact, the purpose of the national grid is very clear, once the plan is integrated into national strategies and plans, related transmission project and associated works will can have easier access and accelerate the construction of state-sanctioned, in order to avoid the national grid was again the issue of wind power grid criticized by others.
According to reports, the current wind power projects and power projects approved out of line, state and local approval, respectively, the first batch of wind power projects approved after making a number of wind power projects not completed in time grid.
“Wind power is split local government approval of drilling policy loopholes, but the power project can not be split.” Participants who asked not to be named, told this newspaper. Prior to our reporter in Inner Mongolia, Liaoning and Guangdong on-site interviews learned that, in order to speed up the approval, the wind power project was split into a number of 50,000 kilowatts of small projects approved by the provincial Development and Reform Commission is a common phenomenon, which sequential expansion of wind power plan is the reason why.
As with the departure from national planning phase, completion of these projects are often not timely and network. Office of Director of Wind Power in Inner Mongolia Kezuozhongqi poplar reporter’s interview, said there are fewer spin-off approval, the key still have to get the grid and network license.
Shu Yinbiao pointed out that in the planning and construction of wind power, there are some provinces (regions) of wind power development planning uncertainty, adjustment problems often resulted in confusion network construction, wind farms and grid construction inconsistent.
Shi Lishan, also said the current development of small wind turbines still disordered problems, identify their deep-seated reason is that local governments, motivated by profit, regarded in many parts of wind power as a new economic growth point, making the development of severe homogeneous.
National Grid wants the state to the next step to the relevant departments strictly approval process of wind power, wind power split to prevent the building of wind farm construction in order to promote the spread disorder to scale and intensive development.
In addition, wind power engineering and power engineering construction period does not match, also contributed to “grid” one of the reasons is difficult. According to reports, the wind power project construction period is short, usually only the first unit construction period of 6 months, all built around also only 1 year; and long cycle power project construction, transmission lines need to span multiple counties, coordination difficulty Great. Reasonable period of 220 kV transmission project need a year or so, a reasonable period of 750 kV transmission project required two years.
Therefore, wind power base in the required seven provinces (districts) Absorptive of wind power, National Grid proposed uniform approved by the national authorities, arrangements for power construction projects in advance to ensure kilowatt wind power turbines base and supporting construction of power projects, synchronization production. This network of plants, which also need to establish coordination mechanisms, so that the wind farm and power enterprises can be properly linked.
In fact, wind power cross-Absorptive there a need to balance other issues, is to Jiena outside the clean energy, central and eastern central areas need to co-ordinate Bende load and an external source of proportion and controlling the fire power construction scale while speeding the peaking power building, reserved for market space, increase acceptance of wind power capacity.
