ト運転支援装置。 This device is installed above the turbine lower control device of each turbine in a private power generation plant consisting of multiple boilers and turbines, and supports high-efficiency operation of the entire private power generation plant, and is used to set the operation mode of this device. A mode setting section, a turbine process input section that receives the output from the operation mode setting section, receives output signals from the flow rate detector and power detector from each turbine, and converts them into engineering values, and the steam flow rate and fuel of each boiler. A boiler and turbine characteristic setting section that sets the flow rate characteristics and the steam flow rate and turbine output characteristics of each turbine; a turbine constraint setting section that sets operational constraints for each turbine; the turbine constraint setting section; and the turbine process input. The high efficiency of the private power generation plant is calculated by calculating the power demand and steam demand that fluctuate from moment to moment based on the outputs of the power generation unit, boiler, and turbine characteristic setting unit, and searching for the operation amount of each turbine that maximizes the efficiency of the entire private power generation plant. an optimal solution search unit that points out turbine constraint conditions that contribute to operation; an operation support display unit that receives outputs from the optimal solution search unit and the turbine constraint setting unit and displays guidance for achieving high efficiency operation; A private power generation plant operation support device comprising: a turbine setting output section that receives outputs from the optimum solution search section and the operation mode setting section and changes settings of a lower-order control device.
