Interpretation of Guidance on High Quality Development of Distribution Network
As a major energy infrastructure, the distribution network plays an important role in ensuring power supply, supporting economic and social development, serving and improving people's livelihood, especially in the context of the "double carbon" goal, the supporting role of the distribution network is more prominent. It is the access carrier of distributed power supply and electric vehicle charging facilities, and it is the key support for the comprehensive and efficient utilization of various distributed energy sources and the energy saving and emission reduction of power users. In recent years, extreme weather such as typhoons, rain, snow and freezing have caused power outages from time to time, exposing the problem of insufficient safe and reliable power supply capacity of the distribution network.

Prospects for the construction and development of new power systems
The production, transmission, and consumption of electricity and energy often need to be carried out through various types of networks, such as power grids, heat grids, and gas grids. Because of the nature of these networks are the transfer of energy, but in different forms, so collectively referred to as the energy network. The energy network consists of subnetworks of different types of energy (electricity, heating, gas, etc.), which are connected by energy conversion devices (such as generators, pumps, air conditioners, water heaters, etc.).
New power system needs "two rounds" of technical policy to promote
"Under the'double carbon' goal, new energy will replace conventional units for power generation, which will bring three major challenges to the new power system." Guo Jianbo, honorary president of the Chinese Academy of Electrical Sciences and academician of the Chinese Academy of Engineering, believes that the new power system must strengthen scientific and technological innovation and promotion and application.
How to install the transformer?
Install the transformer channel steel foundation on the embedded parts, pay attention to leveling and correction, weld the channel steel foundation and the embedded parts firmly, and apply anti-corrosion paint after removing the coating skin on the welding parts.
What are the causes of transformer oil leakage?
Special transformer transformer has many welding spots and long welding seams, while oil-immersed special transformer transformer is a collection of various welding and connection based on steel plate welding shell.
Accelerate the development of new quality productivity, ensure energy security and promote green transformation
This year marks the 75th anniversary of the founding of the the People's Republic of China and is a key year for achieving the goals and tasks of the 14th Five-Year Plan. Energy is an important material basis and power source for economic and social development. This year's government work report on the development of energy and power to make new arrangements, put forward new requirements: "strengthen the security of energy resources" "actively and steadily promote carbon peak carbon neutrality" "further promote the energy revolution, control fossil energy consumption, accelerate the construction of a new energy system" ...... Around the mission objectives, on behalf of the members of the active advice and suggestions, a common talk about the high-quality development of the energy and power industry.
Three main body is accelerating into the field of energy storage
The industry believes that at present, the trend of the three main bodies entering the energy storage field is very obvious. First, public utility companies, oil and gas, power generation groups and other large enterprises embed energy storage business into traditional energy business through the acquisition of energy storage technology or system integrators; Second, power-related equipment enterprises, such enterprises are actively involved in the energy storage field based on their existing advantages in customer resources and channels. Third, traditional load resource aggregators, these enterprises and distributed energy storage system operators are merging their businesses.
Smart grid, providing strong power support
In recent years, China's power system to speed up to adapt to the large-scale high proportion of new energy direction. In the face of the challenges in the process of low-carbon energy transition, infrastructure networking, network, strong chain has become an inevitable choice. In the future, the distributed smart grid will be further developed, and efforts will be made in key technologies, business models and other aspects to promote a more coordinated development of source, network and storage.
