Combined cycle and straight condensing thermal power combined dispatching system and method

Abstract

The invention provides a combined cycle and straight condensing thermal power combined dispatching system and method, comprising a gas-heating boiler and gas combined cycle, a straight condensing thermal power unit, an air conditioner heat pump, an electric energy meter, a heat radiator, a heat consumption meter, a first remote centralized controller, a second remote centralized controller, a third remote centralized controller and a dispatching control device, wherein the second remote centralized controllers acquires the power consumption data detected by the electric energy meter and the heating consumption data detected by the heat consumption meter, and the dispatching control device controls the operation of the gas-heating boiler and gas combined cycle, the straight condensing type thermal power unit, the air conditioner heat pump and the heat radiator through the first, second and third remote centralized controllers. By acquiring the pipeline distance between a user and the heat source, the combined cycle and straight condensing thermal power combined dispatching system reasonably performs combined dispatching on the originally independently operating straight condensing thermal power unit and the gas-heating boiler and gas combined cycle by using the pipeline distance, effectively reduces the total energy consumption of the gas-heating boiler and gas combined cycle and the straight condensing thermal power unit, avoids waste of fuel resources and simultaneously causes dispatching to be more timely and accurate.

Description

technical field [0001] The invention relates to an urban comprehensive energy supply system, in particular to a method for realizing optimal control of a power system by scheduling heating loads. Background technique [0002] The existing power grid includes two power generation modes: 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 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 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] The physical state of gas heating boiler and gas combined cycle operation is to reduce heat generation and only increase power generation. ...

AI Technical Summary

Problems solved by technology

[0006] It can be seen that the above two patents only solve the problem of how to effectively utilize the electric energy and heat energy produced by the combined heat and power unit.

However, it does not solve the problem of how to control the heating and power generation output that the combined heat and power unit should bear in order to save energy when it is combined with a pure condensing thermal power unit.

[0007] The heating hot water produced by the gas-fired heating boiler and the gas-fired combined cycle has a certain distance to reach the user due to the limitation of the transmission distance and the flow rate of the hot water, while the generated electricity can reach the user in an instant; in the prior art, there is no basis The distance between the gas heating boiler and the gas combined cycle and the heating user, the system and method for the joint scheduling control of the gas heating boiler, the gas combined cycle and the coal-fired pure condensing steam thermal power unit, making the scheduling more timely and accurate, avoid wasting energy
