The invention discloses a thermal power plant combined heat and power generation and compressed air energy storage complementary integration system which comprises a thermal power plant combined heatand power generation system and an insulation compressed air energy storage system. The condition that heat load and power load supply and demand are not balanced in northern Chain can be solved, andmore reproducible electric energy is contained for internet surfing. Meanwhile, the problem that high-grade energy loss and compressor unit compression heat loss are caused since the heat supply and steam extracting parameters of a combined heat and power generation unit are too high is avoided, and cold and hot water tanks are omitted. The system is in a strong-heat weak-power state when the heatload is high and the power load is low, at the moment, a compressed air energy storage unit stores power and releases heat, and the combined heat and power generation unit and the compressed air energy storage unit can supply heat to heat consumers jointly; the system is in a strong-power weak-heat state when the power load is high and the heat load is low, and at the moment, the compressed air energy storage unit absorbs the heat from the combined heat and power generation unit and meanwhile releases heat; and at other moments, the combined heat and power generation unit works independently,and the heat and power supply capacity can be adjusted with a small range.
