A combined heat and power system based on a gas turbine unit is a combined heat and power system based on a gas turbine unit according to any one of claims 1-10 and 12-14, wherein a new heater (K) is added, and the steam generator (13) is adjusted to have a gas passage connected to the outside so that the steam generator (13) has a gas passage connected to the outside through the new heater (K), and the new heater (K) also has a heated medium passage connected to the outside, thus forming a combined heat and power system based on a gas turbine unit.

16. A combined heat and power system based on a gas turbine unit is a combined heat and power system based on a gas turbine unit according to any one of claims 11, wherein a new heater (K) is added, and the high-temperature generator (5) is adjusted to have a gas passage connected to the outside, so that the high-temperature generator (5) has a gas passage connected to the outside via the new heater (K), and the new heater (K) also has a heated medium passage connected to the outside, thereby forming a combined heat and power system based on a gas turbine unit.
