Description

Technical Field

[0001] The present invention relates to the technical field of intelligent power consumption, and in particular, to a flexible regulation system and method for non-productive air-conditioning loads. Background Art

[0003] Currently, the rapid growth of air-conditioning loads has continuously increased the impact on the balance of electric power and electricity, leading to the continuous intensification of the contradiction between power supply and demand. It has become difficult to ensure the safe and economic operation of a new power system mainly based on new energy only relying on the regulation ability of the power source side. In contrast, load-side resources have the characteristics of diversification and high flexibility. Therefore, it is necessary to promote the transformation of the power system from "source following load" to "source-load interaction".

[0004] Relying on the new power load management system, the present invention incorporates commercial building and residential air-conditioning loads into the adjustable load resource database, further enriches the demand response and load management resource pool, realizes the accurate monitoring and flexible adjustment of adjustable air-conditioning load resources, improves the level of air-conditioning load management, and provides a basic condition for users to execute power demand response. Summary of the Invention

[0005] Aiming at the deficiencies and defects existing in the prior art, the present invention provides a flexible regulation system and method for non-productive air-conditioning loads, realizes the accurate monitoring of adjustable air-conditioning load resources, and thus realizes the control of the working state of the air-conditioning module.

[0006] The object of the present invention can be achieved by the following technical solutions:

[0007] A flexible regulation system and method for non-productive air-conditioning loads, characterized in that it includes a master station system, a flexible regulation terminal, and an air-conditioning regulation module, wherein:

[0008] The master station system is connected to the flexible regulation terminal and is used to send demand response tasks to the flexible regulation terminal;

[0009] The flexible regulation terminal is connected to the air-conditioning regulation module and is used to send acquisition and control commands to the air-conditioning regulation module according to the demand response tasks sent by the master station system;

[0010] The air-conditioning regulation module is connected to user-side devices, and the user-side devices include a central air-conditioning centralized control system, a central air-conditioning unit, a multi-connected air-conditioning outdoor unit, and an infrared decentralized air-conditioning, and is used to parse the acquisition and control commands sent by the flexible regulation terminal into the modbus protocol for communication with the corresponding user-side devices.

[0011] A flexible regulation system and method for non-productive air-conditioning loads, characterized in that it is applied to the flexible regulation system for non-productive air-conditioning loads described above, and includes:

[0012] Step 1: The master station system enters the archives and sends the archive message, the acquisition plan, and the control command to the flexible regulation terminal;

[0013] Step 2: The flexible regulation terminal establishes the archives according to the archive message sent by the master station, and sends the acquisition command and the control command to the air-conditioning regulation module according to the acquisition plan and the control command, so as to realize the flexible regulation of the non-productive air-conditioning system load.

[0014] Furthermore, the archive entry is divided into two parts: the archive entry of the air-conditioning regulation module and the archive entry of the master station system. To realize data acquisition, it is necessary to ensure the consistency of the archives on the master station system, the flexible regulation terminal, and the air-conditioning regulation module side. Among them, the archives in the flexible regulation terminal are realized by the method of the master station system sending down, while the archives on the master station system and the air-conditioning regulation module side are entered manually.

[0015] Furthermore, the master station system and the flexible regulation terminal are directly remotely connected by using the terminal uplink protocol, the flexible regulation terminal and the air-conditioning regulation module are connected by using the 645 protocol broadband carrier channel, and the air-conditioning regulation module and the non-productive air-conditioning are connected by using the modbus protocol RS485 channel.

[0016] Furthermore, the acquisition tasks sent by the master station system include the load data and the on / off state of the user-side equipment. After the master station system obtains the acquisition data reported by the flexible regulation terminal, it obtains the operation state and the load data of the user-side equipment. The flexible regulation terminal can store the acquisition data, and the master station can directly read the historical load data.

[0017] Furthermore, the master station system sends the parameter adjustment control command to the air-conditioning centralized control system or the air-conditioning unit according to the load data and the on / off state of the user-side equipment reported by the flexible regulation terminal, combined with its own load regulation strategy. Among them, the flexible control command interaction uses ciphertext, and other data interactions can use plaintext or ciphertext.

[0018] Furthermore, the control commands are sent between the master station system and the flexible regulation terminal, and between the flexible regulation terminal and the air-conditioning regulation module by using the data transparent transmission method.

[0019] Furthermore, the air-conditioning centralized control system also belongs to the user-side equipment, is connected to the central air-conditioning unit and the outdoor unit of the multi-connected air-conditioning, and by adjusting the load parameters of the air-conditioning centralized control system, the unified regulation of the non-productive air-conditioning system load can be realized.

[0020] The beneficial effects of the present invention are:

[0021] This application establishes a flexible regulation system for non-productive air-conditioning loads, which integrates a new-type power load management system, a flexible regulation terminal, and an air-conditioning regulation module. By reporting the load data and on / off status of central air-conditioning units, multi-connected air-conditioning outdoor units, and decentralized air-conditioning to the master station system, the master station system analyzes the data and issues relevant parameters such as controlling the temperature adjustment of the air-conditioning system, thereby realizing the flexible regulation of the non-productive air-conditioning system load and effectively alleviating the problems of rising electricity costs, deteriorating grid load characteristics caused by the sharp increase in summer air-conditioning loads, and power shortages.
