1、 Overview of the Power Equipment Industry
Power system mainly includes two categories: power generation equipment and power supply equipment. Power generation equipment mainly includes power station boilers, steam turbines, gas turbines, water turbines, generators, transformers, etc. Power supply equipment mainly includes transmission lines, transformers, contactors, etc. of various voltage levels. There are many power equipment in the power system, and according to their different roles in operation, they are usually divided into electrical primary equipment and electrical secondary equipment. During the use of power equipment, it is affected by wear, corrosion, and other factors, resulting in a decrease in equipment reliability and the possibility of technical deterioration or even accidents. Power equipment status detection and monitoring products mainly detect and monitor the electrical and mechanical status of power equipment to obtain information on its operation status, quality, etc., in order to timely discover the development status of various deterioration processes, and to repair and replace them in a timely manner before possible faults or performance degradation affect normal operation, thereby ensuring the safety, stability, and reliability of the entire power grid operation.
In recent years, the supervision of wire and cable manufacturing and power equipment by the government has been continuously strengthened, and testing standards have been continuously improved. Against the backdrop of stricter regulation, while the demand for power equipment testing continues to grow, testing institutions with strong research and development capabilities, high brand and credibility recognition, are expected to benefit first.
The upstream of China's power equipment industry chain includes steel, electronic components, non-ferrous metals, instruments and meters, insulation parts, rubber and plastic, etc; Mid stream refers to various power generation and power supply equipment; Downstream applications include thermal power generation, wind power generation, photovoltaic power generation, hydropower generation, biomass energy generation, nuclear power generation, and other fields.
2、 Industry Background Analysis
The construction of smart grids is gradually increasing the size of distribution networks, and the digitization of power grids is accelerating. The power equipment testing industry is facing an upgrade in demand and functionality. At present, the main grid structure of China's smart grid is gradually improving, and the construction of the power grid is accelerating towards the radiation of the distribution network side and the digital transformation of the overall power grid; At the same time, after undergoing large-scale smart grid construction, the stock of assets in operation is huge. With the goal of increasing the annual fixed assets investment of the State Grid, the prosperity of the power grid industry continues to rise, and the power equipment status detection and monitoring industry continues to open up growth space. In 2022, major power enterprises in China completed a total investment of 1247 billion yuan, an increase of 15.6% compared to the previous year. The investment in the construction of national power supply projects reached 746.4 billion yuan, an increase of 27.2% compared to the previous year. The investment in the construction of the national power grid project reached 500.6 billion yuan, an increase of 1.8% compared to the previous year. Accelerated release of power investment, maintaining a high level of investment in the power grid. As of January July 2023, major power generation enterprises in China have completed an investment of 401.3 billion yuan in power supply projects, a year-on-year increase of 54.4%. The investment in power grid projects has reached 247.3 billion yuan, a year-on-year increase of 10.4%.
