Patent ID: 7895023

Claim:
A simulation system including a computer processor and a memory, said system establishing reservoir operational rule curves, said simulation system comprising: a reservoir storage computing unit for receiving initially assigned reservoir storages and corresponding hydrological data, and for computing, by the computer processor, reservoir storages of consecutive time units of a plurality of simulation time periods under different initially assigned reservoir storages; a parameter computing unit for receiving pre-specified demands, and for computing respective water shortage parameters of the time units under each of the initially assigned reservoir storages based on the reservoir storages from said reservoir storage computing unit; a statistical unit for making statistics of respective probabilities of the water shortage parameters, and statistical data sets of corresponding relationship among the reservoir storages, the water shortage parameters and the probabilities of the water shortage parameters for a same time unit of the simulation time periods under different initially assigned reservoir storages; a storage trajectory establishing unit for retrieving, from the statistical data sets, values of the reservoir storages of the time units that have specified water shortage parameters and respective probabilities of the specified water shortage parameters, and for collecting the values of the reservoir storages of the time units to generate storage trajectories that respectively comply with the pre-specified demands; and a rule curve screening unit for combining the storage trajectories that comply with the different pre-specified demands to generate different operational rule curve sets, for receiving a specified screening criteria, and for selecting the operational rule curve sets that comply with the screening criteria.
