Smart grid construction drives the development of power transmission and transformation equipment
On July 31, the State Council held a standing meeting to strengthen the construction of urban infrastructure. It was determined in the direction of investment to strengthen the construction of urban distribution networks, promote the intelligentization of the power grid and strengthen the construction of rail transit. The state further promotes power grid construction: At the national level, this is the first time in recent years that the smart grid and distribution network construction have been the investment direction. Five years ago, in order to stimulate domestic demand countries to increase investment in power grid construction, both the State Grid Corporation of China and China Southern Power Grid Corporation have stepped up their investment in power grids. Power equipment companies have benefited from the growth of power grid investment and demonstrated a wave of spectacular market conditions. This time, we once again proposed to strengthen the construction of urban distribution networks and promote the intelligentization of power grids. We understand that in order to ensure economic growth, one of the measures to adjust the economic structure. Policy Portfolio Boxing: This policy is not only to strengthen the power supply capacity of the city's distribution network, but also conducive to the access of distributed power sources such as photovoltaics, and to respond to the impact load of electric vehicle charging and switching stations and charging piles, etc. Car policy echoes support. The task of distribution network construction is a long way to go: Shenzhen and Shanghai, with their power supply reliability indicators, are still subject to widespread power outages. As of 2009, China's distribution network automation coverage rate is only 9%, even if it is one of distribution automation pilot cities in Hangzhou as of May 2013, distribution automation coverage was only 50%. Distribution network construction tasks have a long way to go. The grid company has prepared for distribution network and intelligent construction: 1) China Southern Power Grid Corporation has previously planned a total investment of 227.9 billion yuan in the construction of agricultural distribution network during the 12th Five-Year Plan period, and there will be 1505 investment in the agricultural distribution network in 2013-2015. Billion yuan, an annual average of 50 billion yuan compared with 2012, an increase of 33.3%, of which the growth rate of urban distribution network investment will be higher. 2) State Grid Corporation defined distribution network construction as “an urgent task†at the 2013 mid-year meeting; article titled “Improvement of Power Supply Reliability to Accelerate the Construction of Modern Distribution Network†was published on the front page of the “State Grid News†on July 17. At the same time, commentator articles were distributed; the State Grid Corporation’s 8-year investment plan of 3 trillion yuan, the grid intelligence and distribution network construction funds can be fully protected. The central government, local governments, and power grids cooperate with each other: It is expected that the most troublesome land and power corridors in the construction of urban power distribution networks will receive comprehensive consideration from local governments in strengthening urban infrastructure construction. It can be foreseen that the distribution network construction will usher in a new period, shorten the time of power outages, and meet the new trends of distributed power, microgrid, and electric vehicles.
The power grid equipment company is ready to share: The smart grid construction has entered the stage of ramp-up, and it is expected that the smart substation market will grow by 20-25% in the next five years, and the smart power distribution market will increase by 30%. Intelligent switch cabinets and high-efficiency energy-saving transformers to be used in distribution network construction also have industrial scale. Typical representatives of the company include Nan Rui Ji Bao, Guodian NARI, XJ Electric, Sifang, Siyuan Electric, Jicheng Electronics, HKUST Smart, Changyuan Shenrui, and Guodian Nanzi.
Strengthening the construction of rail transit such as subways and light rails is also one of the tasks for this conference to deploy and strengthen urban infrastructure construction. In 2012, the National Development and Reform Commission approved 609 billion yuan in rail transit projects, and has recently decentralized the approval of rail transit. This year, the situation of tenders for railway construction bids is excellent. In the already-invited lines, 60% of the bids for NARI won the bid, and there are 17 lines for tendering this year.
