Talking about the Development of Power Transmission and Transformation Industry

China is currently the world’s largest energy producer and consumer. Safe and stable supply of energy has become an important support for economic and social development.

However, due to the various economic development speeds in various parts of the country, regional power consumption gradually presents problems of power imbalances, such as “high in the east and low in the west” and “the load of rural electricity is dispersed”. In the past, the state resolved its approach to power supply construction in high-powered cities, following the principle of regional self-sufficiency.

However, with the rapid development of coastal areas in recent years, the density of thermal power construction in developed regions has driven the national average far beyond the national average. This has led to a rapid decrease in the environmental carrying capacity of the coastal areas and frequent smog and haze. Rural households often also experience high transformer air consumption. In the face of energy and energy imbalances in the eastern and western regions, as well as high air consumption in rural areas, whether or not the energy structure can be adjusted through space and time and the improvement of the environment in the eastern region has begun to attract attention.

In order to regulate this kind of energy contradiction, in recent years, the country began to transfer the main battlefield of power construction from power supply construction to power grid construction. According to the statistics of the China Electricity Council, the power grid investments for 2008-2013 were respectively 289.5 billion yuan, 389.8 billion yuan, 344.8 billion yuan, 368.7 billion yuan, 366.1 billion yuan and 389.4 billion yuan. At the 2014 State Grid Corporation Working Conference, the State Grid Corporation of China plans to complete 403.5 billion yuan in investment in fixed assets this year, of which grid investment is 381.5 billion yuan, and investment growth is close to 20%.

According to the National Development and Reform Commission's "12th Five-Year Plan" for the power industry and the 2020 Development Plan (Draft), it is expected that the total power grid investment during the "12th Five-Year Plan" will reach 2.5 trillion yuan, and the annual investment will exceed 500 billion yuan.

As the country’s investment in power grids has increased, various related policy guidelines have also been introduced. In 2011, the country decided to implement a new round of upgrading and upgrading of rural power grids. This time, the rural power grid will invest 200 billion yuan, according to 60%- 65% of the investment is measured by equipment, and about 120 billion yuan is spent on the purchase of power transmission and transformation equipment, including transformers, switches and cables. In January 2014, the National Energy Administration proposed to strictly control the coal power projects in the Yangtze River Delta, the Pearl River Delta, and the Beijing-Tianjin-Hebei region at the National Energy Work Conference, focusing on the construction of coal-fired power stations and new energy bases in the northwest and emphasizing the construction of 12 “western regions. East to send "transmission channels to solve the issue of energy base energy delivery.

The "12th Five-Year Plan" of the power industry and the "New Energy Industry Development Plan" approved by the State Council suggest that China's power grid construction investment will reach 1.5 trillion yuan during the 12th Five-Year Plan period. Intelligent substations will be rapidly promoted and become important for the smart grid. As part of the project, UHV line construction will be fully carried out, and in 2015 it will form a “three vertical and three horizontal and one ring network” UHV AC grid in the “Sanhua” region (North China, East China and Central China).

Driven by the twin engines of a series of national investments and policies, the power transmission and transformation and control equipment manufacturing industry for power grid construction has ushered in a broad space for development. According to the statistics of the National Bureau of Statistics, China's transmission and distribution in 2008-2013 The output value of enterprises above designated size in the power and control equipment industry was 651.729 billion yuan, 732.894 billion yuan, 810.253 billion yuan, 1.075418 billion yuan, 1.4245.37 billion yuan, and 167.332 billion yuan respectively, and the industry showed steady growth.

With the development of China’s economy, the demand for electricity is increasing day by day, and the investment in power grids is increasing. Transmission and distribution and control equipment will continue to maintain steady growth in the next five years. According to the analysis of Roland Berger’s database, by 2015 China’s transmission and distribution And the market for control equipment will be close to RMB 320 billion.

The substantial expansion of the power transmission and transformation industry led to the influx of large numbers of companies, the rapid expansion of production capacity, and the emergence of some drawbacks. Take transformer sub-sectors of transmission and substation as an example. The relevant research report shows that in recent years, China’s annual transformer demand is around 1.5 billion KVA, while the transformer industry’s capacity is 3 billion KVA. The transformer industry is facing “overcapacity and industry dispersion”. problem. In August 2012, the State Council issued the “12th Five-Year Plan for Energy Saving and Emission Reduction” in a timely manner, clearly requiring that the no-load loss be reduced by 10%-13%, and the load loss be reduced by 17%-19%. This brings about the development of energy-saving transformers. The space also brings new impetus to the transformation and development of the transformer industry.

It can be seen that in the future transformers and even the power transmission and transformation industry will mainly develop in two directions: always developing in the direction of high pressure and ultrahigh voltage, mainly 800KV and 1000KV (mainly used in long-distance transmission and distribution lines); , energy-saving, miniaturization of the direction of development (mainly used in urban and rural power transmission lines). Under the continuous development of the national economy, it is expected that grid investment will continue to maintain the trend of high investment and steady growth, and the power transmission and transformation industry will also grow rapidly in this “spring” period.
