Abstract: A system, for simulating a heat and power supply facility, that is capable of easily constructing a heat and power supply facility, and that performs a simulation so as to approximate operating conditions including a load factor to an actual situation, by approximating, to a high accuracy, any item included in a total combined energy to a target value.

Abstract: There is provided a system, for simulating a heat and power supply facility, that is capable of easily constructing a heat and power supply facility, and that performs a simulation so as to approximate operating conditions including a load factor to an actual situation, by approximating, to a high accuracy, any item included in a total combined energy to a target value. A system configuration setting section (30) 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.
