North Star Transmission and Distribution Network News: The distribution network is the link that connects users

The distribution network refers to the network that plays a role in the distribution of electrical energy in the power grid (the power network that receives electrical energy from the transmission grid or regional power plants and distributes it to various customers on-site or gradually through distribution facilities). It is the link between power grid enterprises and users.

The distribution network automation system is the peripheral nerve of the distribution network

Distribution network automation is based on a primary grid and equipment, with the distribution automation system as the core, comprehensively utilizing multiple communication methods to achieve monitoring and control of the distribution system, and through information integration with related application systems, achieving scientific management of the distribution system. The main station of the distribution network is like a brain, sensing the status of the distribution network equipment through terminals (sub stations), making decisions, and then controlling the distribution network equipment through terminals (sub stations), thereby achieving "automated" control of the entire distribution network.

Energy Internet will promote the third industrial revolution

The energy internet is an energy interconnection network based on renewable energy power generation technology, which realizes real-time, high-speed, two-way power data reading and renewable energy access through intelligent energy management system. Its essence is to achieve the maximum on-site balance of electrical energy through the widespread use of information networks, wide area measurement, high-speed sensing, high-performance computing, intelligent control and other technologies, improve energy flow efficiency, and create conditions for the access of renewable energy (especially distributed energy). China's distribution network is relatively weak, with long-term arrears in investment and construction. The network structure is relatively weak, and the reliability of power supply needs to be improved. The line loss rate needs to be reduced, and the coverage of distribution network automation is far below the level of developed countries. The capacity to accept distributed energy and diversified loads is insufficient, and there is great room for construction and renovation.

The distribution network will face significant investment and construction

Since 2013, the construction of distribution networks has become a national task, but concerns about the separation of transmission and distribution have hindered power grid companies from investing in the construction of distribution networks. This year's "new power reform" has been implemented, clarifying that transmission and distribution are still integrated. The objective situation of weak distribution networks and the demand for stable growth to support the economy will drive investment in the power grid. The distribution network is expected to experience rapid development, with an expected growth rate of 60% for primary equipment and * for automation equipment in the distribution network.
