| Abstract: | It is the main energy-saving method that encourage to use frequency conversion technology on large power motor. It is also encourage to use the technology on operation equipment by reform. There are three sets of 390MW gas-steam combined cycle unit in running. Condensate pumps are constant speed pump, it supply feed water to low drum. It＇s power more than the requirement, condensate pumps consumpes much energy than needs. In the works of reform condensate pumps, frequency conversion technology is used on it. In the project, full process variable speed control logic to control condensate pump speed in any case are designed. The regulation system meet requirements of regulation low drum level under high load. It achieves the purpose of. energy-saving. |
