Abstract
PURPOSE: To optimize steam distribution by determining whether or not the bleeding flow rate set point or the exhaust flow rate set point is within the range of steam supply remaining power and simultaneously controlling the steam flow-in amount to each turbine.
CONSTITUTION: The status amount which is required for calculating the steam supply remaining power, such as heavy oil flow rate, evaporation amount, etc. is detected by using each detector 30 that is mounted on boilers 11W1n and applied to an arithmetical unit 40. The arithmetical unit 40 calculates the bleeding flow rate or exhaust flow rate set point of turbines 3 and 4, redistributes excessive or insufficient steam to a turbine which has remaining power, and determines the bleeding or exhaust flow rate set point of all the turbines. The result is transmitted to the turbine controllers 50 of the turbines 3 and 4 and adjusts the steam flow-in amount to the turbines 3 and 4. This enables optimum control.
