Second, the development environment of UHV industry
(1) Relevant national policies support industrial development
The development of the UHV industry is conducive to optimizing the layout of the mainland power grid and power supply, promoting the coordinated development of the power industry as a whole and the regional economy, and effectively realizing the allocation of energy and resources. Therefore, the mainland has issued a number of policies to promote the sustainable development of the UHV industry. In May 2021, the National Energy Administration issued the Notice on Supervising the Investment Effectiveness of Typical Power Grid Projects such as Jiuhu UHVDC, which is mainly based on whether key indicators such as the actual operation of the project, the reliability after the project is put into operation, and whether the transmission loss rate and other key indicators have reached the expected level, and the consistency of the technical plan with expectations.

(5) Internet of Things technology provides technical support for the industry
In recent stages, the State Grid Co., Ltd. has put forward the strategic goal of "building a full-service ubiquitous power Internet of Things" to create an energy Internet that integrates energy flow, business flow and data flow. With the development of Internet of Things technology, the application of Internet of Things in power systems has received more and more attention.
On the basis of continuing to build and operate a strong smart grid with UHV AC and UHVDC power grids as the grid and the coordinated development of power grids at all levels, we will integrate the latest Internet of Things, artificial intelligence, big data storage and analysis, cloud computing, and mobile Internet technologies to improve the level of informatization, intelligence, and intensification of the State Grid system, so that the energy and resource allocation capabilities of the State Grid will continue to improve, reduce wind and light curtailment, and improve energy utilization efficiency and quality。
At present, the State Grid has carried out pilot projects in the construction of ubiquitous power Internet of Things in UHV 5G applications, big data applications, intelligent terminals, State Grid cloud, IoT management platform, report optimization, etc., and various applications are gradually landing. Starting from the characteristics and requirements of UHV substation equipment operation and maintenance, the application prospects of IoT technology in UHV equipment status detection, fault intelligent diagnosis and analysis processing, operation and maintenance management are analyzed, so as to provide a reference for the construction of power Internet of Things in substations.
Third, the current situation of uh-high voltage market
(1) The length of UHV engineering lines
Benefiting from infrastructure stimulation and environmental protection demand, UHV project construction has accelerated, and the cumulative length of UHV projects has increased rapidly from 16,937 kilometers in 2016 to 35,868 kilometers in 2020, with a compound annual growth rate of 20.63%. After experiencing a slowdown in the pace of investment in 2019, the Chinese government will increase its investment in UHV in 2020 due to the impact of the epidemic and economic pressure on China's economy, and UHV investment will be fully restarted on a large scale, ushering in a new round of construction climax again.
