永磁同步电动机在电厂节能改造中的应用研究OA

Compared with traditional asynchronous motors,AC permanent-magnet synchronous motors have high efficiency,high torque,and speed regulation,and have application value in auxiliary transmission equipment in power plants.It studies the types and characteristics of permanent-magnet synchronous motors,and analyzes and optimizes the energy-saving evaluation indicators for motor renovation.It designs a permanent magnetization transformation plan for the fan motor of the air-cooled island in the power plant,and carries out the evaluation of energy conservation and emission reduction effects and economic benefits.Through a systematic analysis of the motor types,transmission methods and operating conditions in the auxiliary equipment system of power plants,it proposes a typical transformation scheme for permanent magnet synchronous motors suitable for coal-fired units,which can provide technical references for the transformation of similar projects.
