Power electronics development opportunities
- Sep 24, 2018 -

The power equipment manufacturing industry generally includes four sub-sectors: power generation equipment industry, power transmission and transformation primary equipment industry, secondary equipment industry, and power environmental protection industry. The development of the power equipment industry depends on the development of the power industry. The scale and direction of power investment directly affect the development of the power equipment industry.

In 2008, with the decrease in downstream demand for power, the new production capacity of the power industry decreased year-on-year; the capacity of renewable energy generation increased, among which the increase in wind power generation capacity was the largest; the capacity of equipment was increased; and the utilization of power generation equipment tended to be utilized. Renewable energy power generation equipment.

In early November 2008, the central government launched a 4 trillion investment plan and 10 measures to expand domestic demand and promote economic growth. Of the 100 billion new investments invested in the fourth quarter of 2008, 4 billion yuan was used for urban power grids and rural power grid construction. . On November 14, 2008, State Grid and China Southern Power Grid announced their specific grid investment quotas for the year and the next two years. Stimulated by the investment plan, the performance growth of the power equipment industry in the next two years is basically no suspense. Unlike other sectors that benefit from investment, the two major power grids announced the investment quota at the first time, which made the power equipment industry take the lead. .

Power electronics technology can achieve control and energy saving, and use "coarse electricity" to "fine electricity". The manufacturing technology of power electronic devices is the foundation of power electronics technology. China has a large gap with foreign countries in this link. The overall energy use efficiency of China and advanced countries is 10% worse. Industrial energy consumption is mainly electricity consumption, accounting for 45% of total energy consumption, far exceeding the average level of developed countries by 23%. In the next five years, energy conservation will become a pillar-strategic emerging industry in the country. It is conservatively estimated that the energy-saving output value in 2020 will be 13 times that of 2010.
