Abstract：To address the issues of declining auxiliary equipment efficiency and rising coal consumption for power supply caused by low-load operation of coal-fired power units under the background of deep peak shaving in coal-fired power,and to assist in achieving the'double carbon'goals and the transformation to the new generation of coal-fired power,research on the application of permanent magnetization technology for coal-fired power auxiliary equipment is carried out.Through data calculation,case comparison and technical characteristic analysis,the current energy consumption situation of coal-fired power auxiliary equipment and the limitations of asynchronous motors are sorted out,and the technical advantages of permanent magnet motors are analyzed.Based on actual renovation cases,verify its application effect and analyze the constraints currently faced by the promotion of the technology.The results show that if permanent magnet auxiliary machines are fully applied in the country's coal-fired power plants,it is estimated that 200 million tons of standard coal can be saved annually,and about 50 million tons of carbon dioxide emissions can be reduced.Currently,the promotion of permanent magnet auxiliary machines still faces challenges such as an incomplete industrialization system and insufficient pilot demonstrations.The promotion of permanent magnet auxiliary machines still faces challenges such as an incomplete industrialization system and insufficient pilot demonstrations at present.Research suggests that the permanent magnetization technology for auxiliary equipment is a key path to breaking the problem of excessive coal consumption under low load in coal-fired power and promoting the clean and efficient transformation of the new generation of coal-fired power.It is necessary to accelerate its large-scale application through measures such as industrial innovation and standard improvement.
