| Abstract: | Automatic switching devices for auxiliary power supply have been widely used in power plants. Aiming at the principles of its application, this paper analyzes the requirements of electric motor switching process, and points out its advantages to plant stable operation and problems by combining engineering practices. To current large capacity units, it is recommended that fast switching mode should be used in HV auxiliary power system, because its short switching time causes almost no disturbance to boiler thermal system. |
