UHV and smart electricity have become hot topics at the two sessions

since the opening of the national two sessions, the support of UHV smart electricity for the development of electric vehicles has become the focus of the representatives, members and the whole society of the two sessions. This newspaper talked to the representatives and members of the national two sessions of the state power corporation system about the power development plan


from the proposals and proposals of the national two sessions, UHV construction is one of the hot topics in the energy field. UHV can not only ensure the power demand of economic and social development in the 12th Five Year Plan, better solve the tension of coal and electricity transportation, but also promote the western development and the coordinated development of regional economy

bright news: changing the mode of energy development is an important aspect of changing the mode of economic development. How do you think we should change the mode of energy development

mazonglin: changing the mode of energy development is a profound change in the energy field, which needs to focus on the whole industrial chain of energy development, allocation and consumption

the key to changing the mode of energy transmission is to base on the overall situation of economic and social development, give full play to the comprehensive collaborative advantages of coal and electricity transportation, and achieve the optimal overall transportation efficiency. Coal transportation and power transmission should be carried out simultaneously. The fundamental role of power network in energy transmission should be further developed

scientifically plan and build UHV and UHV power, and carry out long-distance, high-capacity and low loss transmission of electric energy from China's large-scale coal power bases, hydropower bases and renewable energy power generation bases, so as to promote the optimal allocation of energy resources in a wider range and promote the large-scale development and utilization of clean energy

bright news: Hubei Province is a major economic province in Central China. With the economic and social development, the energy demand continues to expand, and the energy bottleneck constraints facing Hubei are becoming increasingly prominent. How do you view the role of accelerating the construction of UHV in solving the problem of power shortage in Hubei

Xie Mingliang: 60% of the electricity consumption in Hubei province depends on thermal power, and 98% of the coal for power generation needs to be purchased from other provinces. The current energy structure of Hubei Province, in the dry season in winter, seasonal and periodic power shortages are very prominent, affecting local economic and social development and people's lives

accelerating the pace of UHV construction is a realistic choice to resolve the energy bottleneck in Hubei. In recent years, we have been calling for accelerating the construction of UHV power and solving the problem of power shortage in Hubei as soon as possible. According to the strategic cooperation agreement on economic and social development between Hubei and Inner Mongolia signed last year, the power transmission from Inner Mongolia to Hubei will gradually increase from 2010. By 2012, Hubei Province will receive 5billion kwh of power from Inner Mongolia, and by 2015, it will reach 20billion kwh. Therefore, at the national level, there is an urgent need to speed up the construction of the Wuhan UHV transmission channel in Nanyang, Nanyang, Jinzhong and Southeast Shanxi. The annual transmission power of this channel can reach 80billion kwh, equivalent to 35million tons of raw coal per year. At that time, under the unified deployment of State Grid Corporation of China, Huazhong power will give full play to the role of resource optimization platform to effectively alleviate the contradiction of power load shortage in Hubei during the dry season

bright news: energy conservation and emission reduction is an important work of common concern to the whole society at present. How will UHV power promote energy conservation and emission reduction

Fei Shengying: the task of energy conservation and emission reduction in East China during the 12th Five Year Plan period is very arduous. The installed capacity of coal-fired thermal power in East China is now very dense, even close to saturation

at present, the international community is exerting increasing pressure on China's energy conservation and emission reduction. The party and the state have placed the construction of a resource-saving and environment-friendly society in a prominent position in the development strategy of industrialization and modernization. The new situation requires us to proceed from the overall situation, accelerate the transformation of electricity development mode, and walk out of a low-energy and sustainable development path

we can only make full use of the strong advantages of UHV, such as large transmission power, long transmission distance, small transmission loss, and less land occupation, to transmit clean energy or clean energy such as southwest hydropower, Sanxi coal power, and northern wind power to the eastern load center on a large scale, greatly reduce the pressure on resources and environment in the eastern region, and promote the coordinated development of regional economy, society, resources and environment, In order to better meet the requirements of building a resource-saving and environment-friendly society

smart electricity

smart electricity reappears in the government work report this year and has been mentioned many times in the outline of the 12th Five Year Plan. The construction of strong smart electricity with UHV as the backbone and the coordinated development of electricity at all levels is in line with China's national conditions and can meet the needs of the development of low-carbon economy. At the same time, to realize the innovative development of smart electricity, the state needs to further introduce supporting policies

bright news: as one of the first seven ten million kW wind power bases in China, Jilin Province, please talk about the role of accelerating the construction of smart power in the development of wind power

Zhang Xianchong: with the rapid development of wind power in Jilin Province, a series of problems such as wind power consolidation and power consumption are gradually emerging. Accelerating the construction of strong smart power is the only way to improve the wind power access, consumption and regulation capacity of Jilin power

smart power accelerates the construction of 500 kV backbone frame by doing a good job in the management of wind power access system, so as to realize the trans regional, long-distance, high-capacity, low loss and high-efficiency transmission of energy, and realize the effective allocation of wind power resources; By adopting advanced control technology and energy storage technology, the acceptance capacity of wind power can be improved; Through the reasonable and economic scheduling of large-scale wind power, the economy of wind power production and operation can be improved

accelerating the construction of strong smart electricity is an objective choice to realize the optimal allocation of energy resources. Jilin province's energy resources and energy demand are inversely distributed. There are wind power clusters in the West and large nuclear power in the southeast. Building a strong smart power and forming a strong power transmission terminal will significantly improve the power carrying capacity, realize the cross regional, long-distance, high-capacity, low loss and high-efficiency transmission of gale power and large nuclear power, significantly improve the ability to optimize the allocation of energy resources, increase the power exchange with surrounding provinces, implement the large-scale optimal allocation of resources, and ensure the security of power supply in Jilin Province

bright news: please talk about how to solve the key technical problems of smart electricity construction

caiguoxiong: the construction and development of smart electricity are faced with many problems, such as the standard of smart electricity and the horizontal spring tension testing machine as the power supply. Each country is taking different road maps in terms of light and heavy priorities according to different national conditions and actual development conditions. China should also adopt different strategies according to the development of different regions. In terms of the development technology of intelligent electricity, it is an integrated technology of many disciplines, such as power technology, information technology, communication technology, computer technology, automatic control technology and material technology. There are many solutions to the technical problems encountered in the construction of smart electricity, even at the current level of science and technology. Therefore, it should be said that the technical solution of smart electricity is not unique. The technical problems in the construction of smart electricity are more about how to determine the best solution according to the national conditions

rural transformation

since last year, the state power company has accelerated the promotion of the popular projects serving agriculture, rural areas and farmers, such as the comprehensive treatment of rural low voltage, actively launched a new round of rural transformation and upgrading projects, continuously increased rural power investment, focused on solving the problem of rural electricity, and promoted the rapid development of rural economy

bright news: at present, what problems still exist in the construction and transformation of Jilin agriculture? How do you think it should be solved

Zhang Xianchong: with the in-depth promotion of the development strategies such as the revitalization of the old industrial base in Northeast China, the development and opening-up pilot area in Changjitu, the construction of 10 billion jin commodity grain base and the adjustment of economic structure, the rural economy of Jilin Province has ushered in the best opportunity period of rapid development, and at the same time, it has also put forward higher requirements and standards for the construction of rural infrastructure

with the rapid development of rural economy, it is necessary to solve the problems and contradictions of insufficient investment in rural infrastructure construction. Jilin Province has carried out large-scale rural power and county construction and transformation in accordance with the national policy of "two reforms, one price and benefiting the people" issued in 1998, with a total investment of 8.038 billion yuan, and the safe and stable operation capacity of rural power has been effectively improved. However, the problems of unreasonable rural power structure, backward technology and equipment, and 40% of rural power has not been transformed in Jilin Province have not been fundamentally solved. The main reason is the serious shortage of power construction capital, which leads to the lagging speed of power construction and affects the speed of economic development. This has become a bottleneck affecting the rapid development of rural economy in Jilin Province. It is urgent for the state to transfer the national debt refinancing funds to the central financial allocation policy to alleviate the problem of insufficient capital investment in agricultural construction and transformation in Jilin Province

bright news: in 2010, the State Grid Corporation of China accelerated the comprehensive treatment of rural low voltage and other popular projects, and actively launched a new round of rural reconstruction and upgrading projects. Please introduce the experience and practice of Hengyang Electric Power Bureau in agricultural transformation

Xiao Liqiong: Hengyang Electric Power Bureau governs 773 large power direct supply villages with the characteristics of 4-phase limited frequency converters. Due to historical reasons, there are many arrears in agricultural reform and the reform rate is low. As of the first half of 2008, there are still more than 1800 villages that have not been transformed, and more than 2400 villages that have been transformed but not improved in the first and second phases of the city

we follow the principle of giving priority to solving the most critical problems, that is, first meet the basic needs of electricity in the unchanged villages, ensure the same price, and ensure that people have electricity and use it well. According to the stage and batch transformation steps, priority should be given to the transformation of the unchanged villages, and then gradually improve the power supply capacity and reliability of the changed villages (including the villages changed in the first and second phases)

in order to make the project arrangement reasonable and fully mobilize the enthusiasm of all parties, our bureau creatively put forward the working principle of "three priorities" for agricultural reform, that is, priority arrangement in line with the requirements and ideas of higher-level agricultural reform policies; The local government and farmers urgently need and actively cooperate with the priority arrangement without work obstruction; Be able to complete the schedule on time and ensure the priority arrangement of safety and project quality

during the 12th Five Year Plan period, Hengyang Electric Power Bureau will vigorously implement the rural distribution transformation and upgrading project, take step-by-step as the strategic deployment, and plan the projects in reasonable stages and batches with three priorities. In 2012, the villages that have not been changed will be cleared, and the villages that have been changed in phase I and phase II with rapid load growth will be improved. In 2015, a new type of Hengyang rural electricity with safety, reliability, energy conservation, environmental protection, advanced technology and standardized management will be basically built, Provide strong power support for the construction of a new socialist countryside

electric vehicles during the 12th Five Year Plan period, the state will continue to increase policy support and accelerate the development and application of the electric vehicle industry. How to build a perfect intelligent charging service network for electric vehicles has become one of the hot topics of the two sessions

bright news: smart electricity has become a topic of common concern in the whole society. What will the State Grid Corporation of China do in terms of serving smart electricity buildings and electric vehicle charging and replacement power stations

Su Shengxin: the state fully supports the development of pure electric vehicle industry. It is estimated that the number of electric vehicles will reach 60million by 2030

in 2011, NEC will build 173 electric vehicle charging stations and 9211 AC charging piles. Expand the coverage of charging and changing facilities, carry out the construction of inter city demonstration projects of intelligent charging and changing service network, and complete the charging and changing service network of electric vehicles in Beijing, Hangzhou, Tianjin, Hefei, Nanchang and other cities. In addition, we should strive for the support of governments at all levels to win
