Abstract:
1. A system for simulating a heat and power supply facility that has a plurality of heat and power supply devices connected to each other, that is supplied with at least electric power and fuel (hereinafter referred to as a “supplied energy”), that produces at least two items (hereinafter referred to as a “total combined energy”) selected from at least electric power, lower-temperature chilled water, chilled water, hot water, hot water for supply, high-pressure steam, and low-pressure steam, and that supplies a utilization facility with the total combined energy, and for obtaining relationships between operating conditions of the heat and power supply devices and an amount used of the supplied energy and/or an amount produced of the total combined energy, the system comprising: an energy load setting section that sets an amount of the total combined energy that is required per day in the utilization facility per time slot; a system configuration setting section that associates in advance the heat and power supply devices with each other and associates in advance the heat and power supply devices with the total combined energy, and selects any of the heat and power supply devices with an operation of an operating condition section, to thereby freely construct a system configuration of the heat and power supply facility in which the heat and power supply devices are associated with each other and the heat and power supply devices are associated with the total combined energy, the heat and power supply devices including at least one heat and power supply device having at least a motor pump; a process condition setting section that sets process conditions of the heat and power supply facility and the utilization facility, the process conditions including at least one of an outdoor air temperature and a wet-bulb temperature; an operating condition setting section that sets whether or not each of the heat and power supply devices is to be operated per time slot, and that sets an operating priority of each of the heat and power supply devices per time slot; and a calculation section that at least calculates an amount produced of the total combined energy to be obtained when the heat and power supply facility is operated in accordance with the operating conditions set by the operating condition setting section, wherein any of the heat and power supply devices have a partial load characteristic, that varies in accordance with the process conditions; and the calculation section makes convergence calculations so as to change a load factor of the heat and power supply devices corresponding to any item included in the total combined energy so that an amount produced of the item converges on a target value set by the energy load setting section, adjust, based on the changed load factor, a balance of the combined total energy associated with at least the corresponding heat and power supply devices, and repeatedly change the load factor of the corresponding heat and power supply devices and adjust the balance until the amount produced converges on the target value, wherein the energy load setting section, the system configuration setting section, the process condition setting second, the operating condition setting section, and the calculation section are implemented by a computer.
