Combined heat and power dispatching system comprising back-pressure type cogeneration unit and dispatching method thereof

Abstract

The invention discloses a combined heat and power dispatching system comprising a back-pressure type cogeneration unit and a dispatching method thereof. The system comprises a cogeneration unit, an air conditioner heat pump, an electric energy meter, a radiator, a heat-consumption gauge, a second remote centralized controller and a dispatching control device, wherein the second remote centralized controller is used for collecting the power consumption data detected by the electric energy meter and the heating heat-consumption data detected by the heat-consumption gauge, and the dispatching control device is used for controlling the running of the cogeneration unit, the air conditioner heat pump and the radiator through a first, second and third remote centralized controllers. A pipeline distance from a user to a heat source is collected and the pipeline distance is utilized to reasonably dispatch the cogeneration unit, which originally runs independently, in a combined form, so that an error between a load value practically required by the system and an electric load predicted value is greatly reduced, the running and the planning of the system are boosted and the dispatching difficulty is reduced.

Description

technical field [0001] The invention relates to an urban comprehensive energy supply system, in particular to a combined heat and power dispatching system and method including a back pressure cogeneration unit. Background technique [0002] Power load forecasting is an important part of power system planning and the basis of power system economic operation, which is extremely important to power system planning and operation. [0003] Power load forecasting includes two meanings, that is, it is used to refer to various electrical equipment installed at users such as state agencies, enterprises, and residents, and it can also be used to describe the value of the electric power consumed by the above electrical equipment. [0004] Power load forecasting is a series of forecasting work on power load. From the perspective of forecasting objects, electric load forecasting includes forecasting of future electricity demand (power), forecasting of future electricity consumption (ener...
