  • Publication number: 20200104542
    Abstract: A simulation results evaluation device applies plural numbers of virtual input parameters (VIPs) of a simulation test of the power generation facility to model data showing virtual behaviors of the power generation facility. The device calculates each of virtual process values (VPVs) with respect to each of the VIPs and a score obtained by multiplying the VPV by a coefficient of a positive value when the VPV is included in a predetermined target range, the coefficient being set for each of the VPVs, the coefficient being assigned such that as a deviation from a predetermined target becomes greater, the value of the coefficient becomes smaller, or a coefficient of a negative value when the VPV is included within a permissible range provided adjacently to the predetermined target range. The device extracts a simulation test condition that satisfies a predetermined evaluation condition based on the calculated score.
