Problems solved by technology
However, this technology cannot control the operating status of the boiler on the primary side. If the primary water temperature setting is unreasonable, it will easily lead to frequent startup and shutdown of the boiler and improve the operating efficiency of the boiler.
In addition, when this technology is applied in the direct supply system, adjusting the electric valve will affect the flow of the external pipe network, which is not conducive to the hydraulic balance of the project, so the application in the direct supply system is limited

The invention provides an intelligent control system and method for multiple boiler loads. The system comprises a first temperature acquisition module, a first calculation module, a second temperatureacquisition module, a load correction module, a second calculation module and a boiler control module, wherein the first temperature acquisition module is used for acquiring an outdoor temperature, the first calculation module is used for calculating a current output load according to the current outdoor temperature, the second temperature acquisition module is used for acquiring an indoor temperature, the load correction module is used for correcting the current output load obtained by the first calculation module according to the current indoor temperature, the second calculation module isused for calculating starting numbers of boilers and a heat supply load of each boiler according to the corrected current output load, and the boiler control module is used for controlling multiple boilers according to the starting numbers of the boilers obtained by the second calculation module and the heat supply load of each boiler. By the system, heat supply quantity of the boiler can be accurately controlled, the comprehensive running efficiency of the boiler is improved, and energy is saved.
Description
Technical field [0001] The invention relates to the technical field of boiler control, in particular to an intelligent load control system for multiple boilers and an intelligent load control method for multiple boilers. Background technique [0002] At present, the boiler control method of small regional boiler rooms is relatively simple. The load of a single boiler can automatically adjust the start and stop and heating load of a single boiler by setting the target outlet temperature. When a single boiler cannot meet the total heating load demand, the boiler can be added. Number of units started. The number of start and stop boilers, the setting of the outlet water temperature, and the output of the load rely on the experience of manual control, which cannot be accurately controlled according to the actual heat required. [0003] At the same time, the current control logic is mainly to control the heating load through the target outlet water temperature. This method cannot accur...
