| Abstract: | To counter the problems existing in the flow rate throttling control of the draught fan and water pumps used in thermal electric power plants, three flow speed control methods are put forward, including adapting the structure of high pressure frequency converter and the bi-transformer, and reducing the end voltage of asynchronous motor. Meanwhile, the main advantages, shortcomings and application range of the three methods are given, which will provide argument accordance for improvement of thermal electric power plants. |
