The Research And Application Of High Voltage Inverter Technic On Power Plant's Condensate System

The high wastage in large power assistant motor is a problem in fire power plants, at the same time these assistant systems are regulated normally by outer damper or regulate valve,this condition exists large power wastage. The author did a lot of research and analysis on this energy-saving task. In these thesis, a new scheme is brought forward to improve the performance of the power plant system, which apply high voltage large power inverter technic in condensate pump, the control of condensate system is modified meanwhile. The analysis of the working effect prove the project correctness. The conclusion can be made that, applying high voltage large power inverter technic in fire power plant's large power assistant motor system can effectively reduce wastage and the maintenance period, moreover can lower the worksite noise. This scheme can improve the whole set's control performance and be recommended to other similar systems.
