摘要： PROBLEM TO BE SOLVED: To maintain the pressure of each boiler at a prescribed value even when pluralities of boilers and steam turbines are separated from each other by controlling each boiler by calculating the set steam pressure and supplied steam allocation ratio of a reference boiler and the required pressure of each boiler other than the reference boiler by using the allocation ratio. SOLUTION: A power plant is provided with boilers, steam turbines, steam lines, and fuel lines. The supplied quantity of steam to each steam turbine is decided based on the power load allocation corresponding to the power demand. The load allocation, namely, the generated quantities of steam from the boilers are decided in accordance with the supplied quantities of steam to the turbines. The required pressure of each boiler which secures the generated quantity of steam of each boiler is calculated and each boiler is controlled based on the required pressure. The required pressure of each boiler is calculated from the formula, where αB(i), αT(i), and fB(i) respectively represent the generated steam allocation ratio, supplied steam allocation ratio, and generated steam allocation and fT(i), f(i)(i+1), and R respectively represent the supplied steam allocation, inter-boiler flow rate, and pipe resistance. In addition, PB(1) and RB(1) respectively represent the set steam pressure and pipe resistance of a reference boiler.
