EP Shanghai 2020 was held in Shanghai New International Expo Center from 3rd to 5th ,Dec. As an annual event in the electric power industry, there are more than 1300 top electric power and electrical equipment companies and brands from over 20 countries and regions are attracted into the exhibition.Qingdao Yunlu reappeared with its energy efficiency improvement solutions in the power sector, and deeply decoded the important role played by energy efficiency improvement and circular economy in carbon neutrality in the power sector, which attracted wide attention.
Carbon Neutrality in Electricity: Improve Energy Efficiency
Since the signing of the Paris Agreement, carbon neutrality has become an international consensus. As the largest emitter of carbon, we have shoulder heavy responsibilities on achieving carbon neutrality.At a time when the energy revolution and the digital revolution are merging, the key to the energy transformation is the power transformation, which will play a key role in the deep carbon reduction of energy.Experts in the industry point out that if China achieves the goal of carbon neutrality in 2060, carbon emissions per unit of power supply in the power industry will drop from the current 600 grams to at least 100 grams per 10 years on average.However, thermal power generation is still the main way of power generation, due to the dispatch ability advantage of thermal power generation and the ability to calm the volatility and intermittency of new energy power, for a long time in the future, China will still be in the era of traditional fossil energy and new energy coexistence, there will not be a major change in coal-based power supply structure.In the long journey to achieve this goal, China's energy and power sector needs to save energy and reduce consumption and develop and promote new technologies.As an important part of energy saving and consumption reduction on the transmission and distribution side, it is imperative to improve the energy efficiency of power equipment on the distribution side, which will also be the only way to achieve carbon neutrality in the power sector.In May 2020, SAIC and SAC released "Energy Efficiency Limiting Values and Energy Efficiency Grades for Power Transformers”,it’s officially implemented on June 1, 2021, distribution equipment side energy efficiency improvement has risen to the national level.
The solution is of great interest
High-end power equipment is favored
As the process of electrification continues to accelerate, in the future, energy will be an electricity-centered system, and the proportion of electrical energy in the end-use energy will continue to increase. The increase in the proportion of electricity consumption is more of a test of the efficiency of electrical energy utilization. Data shows that China's transmission and distribution losses account for about 6.6% of the national power generation, in the power loss, distribution transformers caused by the loss of nearly half of the proportion.
In the company's booth, there are lots of people attracted to amorphous energy-saving high-efficiency distribution transformers. As the world's most advanced distribution transformer for power field, its no-load loss is 60%-80% lower than ordinary amorphous transformers and silicon steel transformers, and the operation process can also achieve energy saving 25%-50%, which is the ideal choice for power energy efficiency improvement.
In addition, amorphous energy-efficient distribution transformers have significant effects on energy saving and emission reduction in other fields.
Rail Transit Field
Shanghai Metro Line 17 is the first line in China to use amorphous transformers, no-load loss is 30% of conventional transformers, effectively reducing energy consumption during the subway downtime and light load time, significantly achieving energy saving and emission reduction, which is also applied in rail transit construction in Beijing, Guangzhou and Nanjing, Chengdu and many other cities.
Data Center Field
Data center is the base of digital economy, but its power consumption is large, and some statistics show that the electricity cost of the server room accounts for half of the total cost of IDC, so it is significant to build a green, energy-saving and emission-reducing data center. In this field, the use of amorphous energy-efficient distribution transformers is conducive to reducing losses and increasing payload efficiency.
New energy generation field
The power loss of new energy generation transformer is one of the important factors affecting the efficiency of new energy generation system, the transformer losses in the PV power plant's transmission line will directly reduce the PV power plant's feed-in tariff during the operation of the plant, which is a waste of electricity for the power grid.So if the traditional transformers are replaced by amorphous energy-efficient distribution transformers in PV power plants, the system efficiency will be effectively improved, and the resulting economic benefits and energy savings will be very obvious.
Charging station field
With the rapid development of the new energy vehicle industry, the number of charging stations as supporting facilities grows. With the increasing demand for fast charging, charging stations need to increase the number of transformers for multi-transformer assembly, charging stations will become larger and larger, and the resulting losses increase. And the charging station power consumption and operating load rate are uneven, amorphous energy-saving high-efficiency distribution transformer will effectively solve the above problems.
