A new round of rural power grid renewal and upgrading successively started
From China Energy News ( October 18, 2010 17th edition) Author: Wang Hai During the "Twelfth five-year" period, the state grid will gradually build a strong rural power grid, with 220 KV voltage grade as the central hub and 110 KV voltage grade as the main network. The programs are introduced successively, and the projects are also successively started.
With the introduction of the programs and the releasing of funds, a new round of rural power grid renewal and upgrading successively started. High focus on planning, heavy investment, various projects, and wide range have become the common characteristics of this round of rural power grid renewal and upgrading.
The China Energy News reporter understood from Jiangxi Province Electric Power Company that, Jiangxi Rural Power Grid Upgrading Planning (Draft) has been reviewed by the expert group of the Provincial Energy Administration. The planning is from 2010-2015, and a total investment of about 26.6 billion yuan will be allocated to Jiangxi Rural Power Grid Upgrading Planning. According to the first draft of the planning, from 2010-2012, Jiangxi province will focus on the comprehensive upgrading of rural power grid under 110 kv and below in 96 counties (districts), and solve the key problems such as the rural low voltage power supply, equipment aging, overloading, and power supply "bottle neck", and improve the rural power supply capability and power supply reliability in the whole province. At the same time, constantly optimize the rural 110 kv and 35 kv power grid structure, and solve the problems of weak linkage of rural single electric power supply and single substation to the main network, the urgent need of power supply for farmland irrigation facilities in major grain-producing areas, as well as power supply for agricultural production facilities with strong leading role. Further improve the province's rural power management system, and realize the same price power supply for urban and rural in the province.
The reporter learned that, on September 14, the first draft of Shaanxi Rural Power Grid Upgrading Project Planning has been officially compiled and entered the review process. The reporter learned that this round of Shaanxi rural power grid upgrading project will speed up the rural power grid upgrading tasks in the areas that were not included in the first and the second rural power grid upgrading projects. Mainly solve the problems of weak linkage of county power grid with the main network, and make overall arrangement on the renovation of agricultural production supporting power facilities, proactively eliminate distribution transformer with high energy consumption, and promote the universal service of power supply.
The reporter also learned that, in mid-September, taking the opportunity of the one hundred day promotion of the "Rainbow Project", Shandong Electric Power launched a new round of rural power grid upgrading projects.
On September 30, the National Development and Reform Commission issued the notice of rural power grid upgrading project planning, and required each district and the two major power grid enterprises to prepare the overall rural grid upgrading planning and three-year (2010-2012) rural grid upgrading planning, and give clear objectives and construction focus for the latter, as well as specific measures for the overall upgrading of rural power grid.
The National Development and Reform Commission also said in the notice that, the objectives and construction focuses of the three-year planning of rural power grid upgrading also include the upgrading of rural power grid that has already been upgraded; Solve the problems of power supply for agricultural production, and the urgent need of power supply for farmland irrigation facilities in major grain-producing areas, as well as power supply for agricultural production facilities with strong leading role (e.g., greenhouse) ; Straighten out the rural electricity management system, and abolish the "proxy" system in the county-level power supply enterprise, and solve the problems of "enterprise and power grid integration", "cross power supply" and so on.
Thoroughly solve the leftover problems
Upgrade for insufficient parts
In recent years, driven by the central policy to strengthen agriculture and benefit farmers, the rural economy achieved fast development. The Appliances to the Countryside policy also promoted the rural household power consumption, which raised higher requirements for rural power supply ability and the quality of power supply. The contradictions between insufficient power supply and fast economic development in some rural areas are becoming more and more prominent. New bottlenecks are emerging in the power supply, and the problems of weak rural grid structure and power construction problems began to emerge.
Restricted by economic development imbalance, investment scale limit, weak capital commitment ability and other factors, the coverage of rural power grid upgrading in some areas is low, especially in Inner Mongolia, Sichuan, Yunnan, Xinjiang and other western provinces, the coverage is obviously low. For example, in Yunnan, the upgrading rate is less than 75%, and in Sichuan and Qinghai, the low voltage power grid upgrading rate is less than 65%. The problems of rural power grid structure and rural power management are quite outstanding.
In July this year, the National Energy Administration hosts a conference to fully deploy the rural power grid upgrading work. The conference required that, within about 3 years, finish the upgrading of rural power grid in all rural areas, and solve the problem of insufficient rural grid power supply. Make sure rural household power supply are guaranteed and the problems of power supply for agricultural production facilities are solved; With province as a unit, to realize the objective of same price power supply for urban and rural; Basically build a new rural power grid with safety and reliability, environment protective, energy-saving, advanced technology, and standardized management.
The new round of rural power grid upgrading will concentrate on the overall upgrading of rural power grid in about 3 years, and solve problems of low coverage of rural power grid in some areas, especially the west remote areas and ethnic minority areas, which have many leftover problems. For upgraded areas, implement re-upgrading if power supply inefficiency happens again due to demand growth. For problems of equipment aging, equipment overloading, insufficient substation distribution, and thin line diameter, and other problems, according to the new construction standard and requirements, through encrypting the power supply facilities, replacing old equipment, and other measures, to continuously meet the power supply need of farmers, and gradually realize the same power supply reliability for the rural power grids and the urban power grid.
In the new round of rural power grid upgrading, it is an important content to ensure the power supply for agricultural production. The new round of upgrading will be based on the characteristics of agricultural production in different areas, and adjust measures to local conditions to implement the power grid facilities for farmland irrigation facilities of major grain producing areas, processing facilities of rural commercial crops and agricultural and sideline products, and livestock and aquaculture facilities. Improve power supply reliability and power supply capacity for agricultural production.
State grid "11th five-year plan" is every family can use electric power
the "twelfth five-year plan" is to build strong rural grids
China Energy News reporter understood from State Grid Corporation that, through the rural power grid upgrading project, at the end of the "11th five-year plan", the State Grid Corporation plans to fully realize the objective of "every family can use electric power", and speed up the promotion and application the "four new" rural power grid technology. Perfect the reactive compensation and automatic pressure regulating function of rural power grid. Actively promote the application of energy saving, loss reduction, and environmental protection technology. Constantly improve the technology and equipment level of the rural power grid, and actively implement rural power grid improvement project and new socialist countryside Construction of electrification engineering. The State Grid will first build a rural power grid with 110 kv(66 kv) and 35 kv voltage grade as the main network frame, and with coordinated development of 10 kv and 380 voltage and below network. The reliability rate of the rural power supply will reach 99.73%; the comprehensive voltage qualification rate of the rural power grid will reach 98.45%; and the average comprehensive loss rate of rural power grid will be below 6.5%, so as to better meet the power supply demand of al all kinds of rural customers.
During the "Twelfth five-year" period, the state grid will gradually build a strong rural power grid, with 220 KV voltage grade as the central hub and 110 KV voltage grade as the main network. Gradually realize ring network power supply for the medium voltage distribution network in the town, and further optimize the network structure to shorten the power supply radius. Further improve the reliability of power supply and the voltage qualification rate.
