Abstract

The invention relates to a system containing a cogeneration unit and a pure condensing steam thermal power unit, comprising the cogeneration unit, the pure condensing steam thermal power unit, an air-conditioner heat pump, an electric energy meter, a radiator, a heat consumed meter and a scheduling control device, wherein the scheduling control device is used for collecting power consumption data detected by the electric energy meter and heating consumption data detected by the heat consumed meter to obtain a scheduling control signal and controlling the running of the cogeneration unit, the pure condensing steam thermal power unit, the air-conditioner heat pump and the radiator. Aiming at energy conservation scheduling during the off-peak period of electric load and energy conservation peak regulation during the low ebb period, the invention performs optimum allocation and control of heating demand and electricity output so as to reduce total energy consumption, thereby achieving the purpose of energy conversation.

Description

technical field

[0001] The invention relates to a heat and power cogeneration energy supply system, in particular to a system including a heat and power cogeneration unit and a pure condensing steam thermal power unit and a scheduling method for controlling the system. Background technique

[0002] There are two power generation modes in the existing power grid: one is to provide electric energy solely from the power generated by the combined heat and power unit, and the other is to provide electric energy solely from the power generated by the pure condensing thermal power unit. These two generator sets operate independently. Among them, the combined heat and power unit supplies electric energy to end users and provides heating energy at the same time. The pure condensing steam thermal power unit can only provide electric energy to end users, and heat energy needs to be supplied by another thermal energy plant.

[0003] During the off-peak period of the power grid load, t...
