| Today's society,economic development more and more quickly,then,need more and more energy to keep up with the pace of economic development.China ranks first in the world in terms of energy consumption.However,the problem is that the storage of natural resources is less and less,the price of energy is getting higher and higher,which is bound to affect China's economic development.Therefore,each country has invested a lot of manpower and resources to study the issue of energy saving.China in the world installed capacity and power consumption are far ahead of other countries,in energy-saving research has great potential.Frequency control technology can improve the energy efficiency,reduce power consumption,the principle is to change the frequency of the motor to adapt to changes in external load.Frequency control technology in a wide range of industries,which are more used in the power generation industry,can effectively reduce the power plant power consumption,reduce power generation costs,improve power plant efficiency.The use of high-voltage inverter on the condensate pump and other types of thermal power plant auxiliary frequency control,to improve the quality of the adjustment,but also can reduce the unit pay,so that the system has a high utilization rate and reliability,and thus save the power plant Resources,improve the power plant economy,reducing the power plant power consumption.Tuoketuo power plant is the world's largest thermal power base,is now put into operation generating 8 × 600 MW,2 × 660 MW,2 × 300MW(owned).Combined with the actual power plant,the No.7,No.8 unit condensate system for domestic frequency conversion,analysis of its energy efficiency,economic effects and application results.The actual proof of the localization of the technology can meet both the requirements,but also has significant advantages,its energy-saving effect is significant,less investment,maintenance more convenient. |
