The energy saving of high voltage pump motor system is one of the ten key energy-saving projects initiated by the national development and Reform Commission. The national development plan requires that the energy saving technology of variable frequency speed regulation should be popularized at present, that is, the general mechanical system of fan, high pressure pumps, compressor and other general mechanical systems should adopt variable frequency speed regulation energy saving measures, and industrial machinery adopts AC motor frequency conversion technology. During the "11th Five-Year" period, China will achieve an increase of 2 percentage points in the efficiency of the motor system, resulting in the goal of generating 20 billion kilowatt hours of electricity per year.
According to industry experts, the total installed capacity of China's high pressure pumps is about 580 million kilowatts, which accounts for 60% to 70% of the total electricity consumption in China. Among them, the AC motor accounts for about 90%. The expert analysis shows that the operating efficiency of all kinds of motors is 3~5 percentage points lower than that of foreign countries, and the efficiency of fans and pumps is 2% to 3% lower than that of developed countries. The overall efficiency of the motor drive system in the whole is nearly 20% lower than that of the foreign countries. If the speed is changed according to 10% of the total capacity of the motor, the annual average operation is 4000, the power saving rate is 20% - 25%, and the annual electricity potential is 32 billion - 40 billion kwh. In addition, the power saving potential of the motor can be brought about by the motor which is modified to improve the process flow. The total power saving potential is about 50 billion kwh, which is equivalent to the annual power plant of a thermal power plant with 10000 MW installed capacity. It can be seen that the energy saving of motor system is the most potential commercial area in China's energy saving market.
