Green, energy-saving, low-power and renewable energy technologies have become the key words of power industry. It is predicted that in 2011, new energy will become an accelerator to boost the development of power industry.
In the context of the current energy shortage, the world ushered in a low-carbon era. In the past five years, China has risen rapidly as a world energy power, with the total primary energy production and consumption ranking first in the world, and the energy structure has been significantly optimized.
Current situation of power industry stage
The development and evolution of power products are closely related to power technology. Power supply technology is an interdisciplinary technology integrating power transformation, modern electronics, automatic control and other disciplines. With the development of science and technology, the progress of power technology is closely related to the development of modern control theory, material science, electrical engineering, microelectronics technology and many other fields.
With the upgrading of power devices, the use of new electromagnetic materials, the progress of power conversion technology, the improvement of control methods, and the integration of related disciplines, China's power industry has entered a rapid development period. Power supply products are developing towards high frequency, high power density, high power factor, high efficiency, high reliability, high intelligence, green and many other directions. Power supply products have made great progress in system reliability and stability, electromagnetic compatibility, elimination of grid side power harmonics, improvement of power utilization, reduction of loss, etc.
Some people in the industry divide Chinese power supply products into three categories: electronic power supply, chemical power supply and physical power supply.
According to the analysis of the present situation of power supply industry, during the 1990s, most of the listed power supply enterprises are power management enterprises. In the five years since 2000, most of the listed enterprises are battery enterprises. From 2005 to now, the listed enterprises take the specific electronic power supply as the main product, involving UPS, power supply, communication power supply and other different types of power supply. In 2010, some key electronic power supply products have achieved a small growth rate, which is slightly higher than the growth rate of GDP, which has played a good role in promoting the development of enterprises.
Forecast Prospect of Power supply Industry
In 2010, the sales volume of the overall power supply industry was increased by 10.4%;the economic environment was loose in the first half of the year, the economic environment was tight in the second half of the year, and the prices of basic raw materials and energy led to higher costs. In 2011, the growth rate of sales in the overall power industry is expected to be 11.3%;the overall economy is basically improving, and the economic performance is the situation of the first low and the second high, bringing new opportunities to the development of the industry. In 2012, the sales volume of the whole power supply industry is expected to grow by 10.6%. With the stable economic growth and the further implementation of the energy saving policy, the green concept power supply will flourish.
