Description

Technical Field

[0001] This invention relates to the field of power supply or distribution devices, and particularly to a branch power supply load control linkage system. Background Technology

[0002] During periods of controlled electricity use, dedicated transformer terminal equipment is commonly used to effectively control a large number of enterprises. This equipment achieves remote power control by monitoring and controlling the on / off status of the terminal remote control ports. These devices communicate with the upper-level control center via wired communication and possess certain remote control capabilities. However, some problems and drawbacks exist:

[0003] Firstly, for industrial enterprises distributed across mixed power lines, traditional dedicated transformer terminal equipment cannot directly perform power-off operations because residential buildings or other public facilities are present in these mixed power lines. This makes simple and effective remote operation of the lines difficult.

[0004] Secondly, many older users' high-voltage switchgear or outdated switchgear lacks remote tripping capabilities, limiting the efficiency of remote load control. This necessitates manual, on-site operation at each household, which is not only inefficient but also prone to disputes and service risks. Furthermore, some industrial users sub-supply residential or public utility systems, making remote operation difficult because these users cannot afford power outages. Additionally, some industrial users' loads involve safety or residential needs, and directly enforcing measures could trigger legal disputes and public opinion risks.

[0005] Finally, when monitoring and controlling loads in commercial and other fields, which involve equipment such as internal elevators, fire protection, and cold storage, existing technologies struggle to achieve precise load decomposition and control. Summary of the Invention

[0006] The purpose of this invention is to provide a branch power supply load control linkage system. This device can accurately distinguish and control industrial and commercial loads to ensure that all users can achieve efficient and controllable power consumption under orderly power use, and solve the problem of unpaid electricity bills for public areas in old residential areas.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A branch power supply load control linkage system includes a load monitoring and control master device, a switch control slave device, and a communication module.

[0010] The switch control device is installed in the distribution cabinet and connected to the drawer switch system of the distribution cabinet for remote control of the drawer switch to cut off power, so as to carry out precise load control for industrial enterprises on mixed lines.

[0011] The communication module is used to realize the linkage control of the master device to multiple slave devices; data is transmitted through wireless communication, the master device issues a power-off command, the slave device receives the command and sends a power-off signal to the drawer switch, thereby realizing the power control of a specific branch.

[0012] Furthermore, the main load monitoring and control equipment includes a real-time monitoring module, a remote control module, a data processing module, a data storage module, and a monitoring operation interface module.

[0013] The real-time monitoring module is connected to the remote control port of the dedicated transformer terminal to obtain the switch status information monitored by the dedicated transformer terminal;

[0014] The remote control module is used to remotely operate the load switch status, thereby enabling load control for industrial and commercial users.

[0015] The data processing module is used to analyze the switching status information of load switches, analyze load data in different regions, identify peak periods and high-load areas, and automatically perform load scheduling and optimization; adjust load distribution in real time to avoid overload and insufficient power supply, improve the stability of the power grid and the quality of power supply; regional load balancing optimization reduces the load pressure on the power supply bureau.

[0016] The data storage module is used to save the switching status information of the load switch, providing support for historical data query;

[0017] The monitoring and operation interface module provides a user-friendly remote monitoring and operation interface, making it convenient for maintenance personnel to monitor the status of the dedicated transformer terminal in real time and perform remote operations.

[0018] Furthermore, the switch status information includes the switch status, current, and constant voltage of the load switch.

[0019] Furthermore, the switch control slave device includes a switch control module and a power distribution interface module.

[0020] The switch control module is used to perform the power-off operation of the drawer switch according to the control command sent by the main device, including power-off and power-on.

[0021] The power distribution interface module is used for connection to the control system of the power distribution cabinet and for controlling the drawer switches, including cutting off power and closing power.

[0022] Furthermore, the communication module adopts a wireless communication network with a single-transmitter-multiple-receiver protocol mechanism, and sets up security mechanisms such as encryption and authentication for the wireless communication network.

[0023] This invention enables precise differentiation and control of the internal loads of industrial and commercial dedicated transformer users, ensuring efficient and controllable operation for all users under orderly power consumption conditions; it enables effective load control for users without high-voltage switchgear or whose old switchgear lacks remote tripping functionality; if a user is in arrears, it cuts off power to a portion of the user's load through the communication channel of the dedicated transformer terminal, prompting the user to recharge and pay; it utilizes the original uplink communication channel of the dedicated transformer terminal and uses the integrated data acquisition platform, eliminating the need for additional platforms and uplink channels, ensuring data security and reliability.

Both the load monitoring and control master device and the switch control slave device are equipped with a communication module, and one master device can connect to multiple slave devices through the communication module.

[0026] The load monitoring and control main equipment is used to monitor the remote control port switch status of the dedicated transformer terminal in real time and provide remote control capabilities, so as to realize accurate detection and remote control of the load switch status of industrial and commercial users.

[0027] The main load monitoring and control equipment includes a real-time monitoring module, a remote control module, a data processing module, a data storage module, and a monitoring and operation interface module. The real-time monitoring module connects to the remote control port of the dedicated transformer terminal to acquire the switch status information monitored by the terminal, including the switch status, current, and voltage setting of the load switch. The remote control module is used to remotely operate the load switch status, enabling load control for industrial and commercial users. The data processing module analyzes the switch status, current, and voltage setting of the load switch, analyzes load data from different regions, identifies peak periods and high-load areas, and automatically performs load scheduling and optimization. Real-time adjustment of load distribution prevents overload and power shortages, improving grid stability and power quality. Regional load balancing optimization effectively reduces the load pressure on the power supply bureau, improves grid reliability and power efficiency, and thus improves the user's electricity experience. The data storage module stores the switch status, current, and voltage setting of the load switch, providing support for historical data retrieval. The monitoring and operation interface module provides a user-friendly remote monitoring and operation interface, facilitating real-time monitoring and remote operation of the dedicated transformer terminal by maintenance personnel.

[0028] The switch control device is installed inside the distribution cabinet and connected to the cabinet's drawer switch system for remote control of the drawer switch to cut off power, enabling precise load control for industrial enterprises on mixed circuits.

[0029] The switch control slave device includes a switch control module and a power distribution interface module. The switch control module is used to perform power-off operations on the drawer switch according to the control commands sent by the master device, including power-off and power-on. The power distribution interface module is used to connect to the control system of the power distribution cabinet and to control the drawer switch, including power-off and power-on.

[0030] The communication module is used to realize the linkage control of the master device to multiple slave devices; data is transmitted through wireless communication, the master device issues a power-off command, the slave device receives the command and sends a power-off signal to the drawer switch, thereby realizing the power control of a specific branch.

[0031] The communication module described in this embodiment adopts a wireless communication network with a single-transmitter-multiple-receiver protocol mechanism, and sets up security mechanisms such as encryption and authentication for the wireless communication network to ensure the security of data transmission. At the same time, it sets up an access control policy to ensure that only authorized personnel can perform load control operations.

[0032] This embodiment also sets up a permission management function for the communication module, which restricts the scope of load control operations for different users according to their permission levels, thereby improving the security and management efficiency of the system.

[0033] When precise load control is required for orderly power consumption or when users are in arrears, the dedicated transformer terminal remote control port sends a power-off control signal. After the main equipment detects the signal, it sends a trip command to the associated slave equipment wirelessly. After receiving the trip command, the slave equipment sends a trip power-off signal to the drawer switch, thereby realizing power control of a specific branch.

[0034] This embodiment enables precise differentiation and control of the internal loads of industrial and commercial dedicated transformer users, ensuring efficient and controllable operation for all users under orderly power consumption conditions; it enables effective load control for users without high-voltage switchgear or whose old switchgear lacks remote tripping functionality; if a user is in arrears, power is cut off to a portion of the user's load through the communication channel of the dedicated transformer terminal, prompting the user to recharge and pay; it utilizes the original dedicated transformer terminal's uplink communication channel and uses the integrated data acquisition platform, eliminating the need for additional platforms and uplink channels, ensuring data security and reliability.
