Aiming at the situation of lacking of reference data in simulation model validation,a method based on characteristic curve reconstruction was proposed and used into model validation.Firstly,the characteristic curve of simulation data time series was acquired through communicating with related experts.Then the parameters of simulation data were estimated using the characteristic curve.Finally,the estimated parameters were compared with the parameters given by experts to validate the simulation model.The results of simulation analysis show that the proposed method can solve the problem of lacking of reference data in simulation validation effectively,and is of certain reference value.
