UHV wire and cable promotes energy competitiveness

In the eyes of energy experts, the characteristics of China’s energy resources determine that the energy development mode must be changed on the spot. The development of UHV power grids can achieve long-distance and large-scale coal and electricity bases, large hydropower bases, and large renewable energy bases. Delivery of capacity, ease of tight coal, electricity and oil transportation, and improvement of the ability to allocate resources in a wider range will also promote the development of clean energy and will increase China's energy supply security. Ukrainian high-voltage is not an opportunity for a major energy province that is changing its development model. Taking Shanxi Province as an example, according to estimates, the two energy transmission methods for coal transmission and transmission have a ratio of 1:6 to Shanxi GDP, and the employment-pull effect ratio is about 1:2. China's power transmission and transformation equipment companies recently received a lot of foreign orders. Because of their participation in the development of UHV engineering equipment, these companies that are used to “bringing in” are undergoing a “going out” shift. With the official operation of the UHV transmission project, China's manufacturing industry has used the “Everest Everest” manufactured by the international electrician for 4 years.

When there are significant gaps in energy demand worldwide, countries are actively developing energy in all areas, and world energy is showing a diversified competitive trend. More importantly, energy is becoming an important part of the economic revolution. The Obama administration in the United States even hopes to completely reshape the production methods and lifestyle of the United States by establishing a clean energy structure and launch the most powerful energy administration force in the history of the United States. Experts believe that the reform of the energy system in Obama’s economic reform plan will be the largest economic, social, and environmental revolution in mankind in the 21st century.

In the world energy landscape, the competitive advantages of different countries are obvious. Russia, the Middle East, and Latin America have rich reserves of oil and gas resources. The United States has the advantage of dollar-denominated petroleum. Europe has stepped up its efforts in new energy sources and is firmly striving for oil pricing. Japan has leading energy-saving technologies and diversified international energy supplies. , Singapore, Panama occupy the geographical advantage of the energy channel.

To participate in competition, China must first solve its own bottleneck in energy development. From water and fire, we must not become water and fire. This is the "magic" imposed by UHV. With the development of hydropower in southwest China, there is also a large amount of electricity in the southwest that needs long-distance transmission. Before 2020, a total of more than 38 million kilowatts of hydroelectric power for the four cascade power plants at Xiluodu, Xiangjiaba, Baihetan and Wudongde in the Jinsha River plus another 24 million kilowatts of hydropower in Sichuan will be sent to Central and Eastern China, and Guizhou to Guangdong Power. More than 10 million kilowatts is also in Yunnan, Yunnan hydropower to send more than 20 million kilowatts in Guangdong.

The development of AC ultra-high voltage transmission to a certain stage will form a strong UHV synchronous power grid, with significant energy savings from networking. The planned North China-Central China-East China UHV AC synchronous power grid will realize close interconnection and interconnection of the three major power grids of North China, Central China, and East China, which can reduce the installed capacity and reduce the power consumption of the abandoned water power. It is expected that by the year 2020, with unified dispatching and unified inspection and maintenance, the country can reduce its installed capacity by more than 20 million kilowatts and save a total investment of 76 billion yuan. The North China-Central China-East China Synchronous Power Grid can reduce the amount of abandoned water by about 6 billion kWh per year, saving about 2.6 million tons of coal.

The national grid company's proposed smart grid is based on the UHV grid as the backbone grid, the coordinated development of the grid at all levels, and supported by the communication information platform, with information, automation, and interactive features, including the power system. Powerful, reliable, cost-effective, clean, environmentally friendly, transparent, friendly, and interactive modern power grids for power generation, transmission, substation, power distribution, power supply, and dispatch, covering the “Sanhua” (North China, Central China, East China) grids, Northwest Power Grid and Northeast China Power Grid, and interconnected with China Southern Power Grid through UHV DC.

According to media analysis, there are at least two advantages that have not yet been brought into full play. That is, we have huge energy demand and purchasing power. However, we have not obtained the right to speak about international energy pricing, what we often buy, and what price rises; we have huge amounts of energy. The demand for technology applications should occupy the commanding heights of the new round of competition under the impetus of industrialization, but they are often subject to mechanisms and concepts, and are caught in the dispute circle of “should not be the first place in the world”, and no clear technical advantages have yet been formed. The reason why UHV engineering construction has attracted a lot of attention is because it has new technologies, expands new thinking, and then promotes the significance of the new pattern.
