Proportional Leading Control Method of Drum Level of Power Plant

摘要

Disclosed is a proportional leading control method of a drum level of a power plant for controlling the drum level more quickly and safely by embedding a proportional preceding controller. The control method of the present invention controls the water level of the power plant drum by treating the drum level as a preceding control element to the comparative operation value of the steam flow rate and the water supply flow rate that affect the drum level change. Therefore, the present invention effectively controls the drum level, compared to the conventional control method to control the steam flow rate and the water supply flow rate change value to the drum level control value, thereby improving the processing speed and operation stability and improving the power plant efficiency. Provide effect.
