The simulation circuit detection device 10 is used to detect the power consumption information of the simulation circuit.

[0029] The simulation line includes a low-voltage busbar and branch lines. The simulation line detection device includes a low-voltage metering device, a busbar detection device, and a branch line detection device. The virtual load is used to simulate the electricity consumption of users below the branch lines.

[0033] Specifically, the system control platform formulates orderly power consumption plans based on the power consumption of each line, and applies these plans to the actual power supply lines. The orderly power consumption plans formulated by the system control platform based on the power consumption of each line can also be used for the upgrading and transformation verification of old power load management systems, the understanding of new power load management systems, learning the working principles of the system, and formulating orderly power consumption plans.

[0034] This embodiment formulates a power consumption plan based on the power consumption information of the simulated line detected by the simulated line detection device, which solves the problem that existing technologies rely on human intervention and analysis to formulate the optimal scheduling and control plan when performing load regulation.

[0035] Specifically, the simulated circuit includes a low-voltage busbar and branch lines. The low-voltage metering device of the simulated circuit detection device is electrically connected to one end of the low-voltage busbar, and the other end of the low-voltage busbar is connected to one end of multiple branch lines. The other end of each branch line is connected to a virtual load. By providing virtual loads, the power consumption information of each branch line is simulated to monitor the power consumption information of each line.

[0036] More specifically, the power load management and control system simulation platform also includes bus circuit breakers and branch circuit breakers. The bus circuit breakers control the on / off state of the low-voltage bus, while the branch circuit breakers control the on / off state of branch lines. By controlling the on / off states of the bus circuit breakers and branch circuit breakers, the power supply safety of the bus lines and branch lines is ensured, and power supply plans are formulated.

[0037] Furthermore, the power load management and control system simulation platform also includes bus circuit breakers and multiple branch circuit breakers. The simulated lines include low-voltage buses and branch lines. The simulated line detection devices include bus detection devices and branch line detection devices.

The branch circuit breakers are communicatively connected to the branch line detection devices, which are used to detect the power consumption information of the branch lines and the on / off status of the branch circuit breakers. By setting up branch line detection devices, the on / off status of each branch line is detected and the on / off status of each branch line is controlled. The branch line detection devices are communicatively connected to the load management terminal to realize the control and status monitoring of each branch circuit breaker.

[0038] Specifically, the system control platform communicates with the load management terminal via Ethernet.

[0040] The load management terminal communicates with the bus detection device via RS485 communication, collecting real-time data and information such as opening and closing status from the bus detection device. Furthermore, by connecting the load management terminal's cycle control line to the bus detection device, it can receive and relay load control commands from the load management terminal. For example, in remote opening operations, the bus detection device receives opening commands and cycle control signals from the load management terminal via RS485 communication, controls the bus circuit breaker to perform opening operations, and detects the opening and closing status of the bus circuit breaker. Similarly, the load management terminal communicates with branch line detection devices via RS485 communication, collecting real-time data and information such as opening and closing status from the branch line detection devices. This same connection, along with the load management terminal's cycle control line, enables the receiving and relay of load control commands from the load management terminal. For example, in remote opening operations, the branch line detection device receives opening commands and cycle control signals from the load management terminal via RS485 communication, controls the branch circuit breaker to perform opening operations, and detects the opening and closing status of the branch circuit breaker.

[0048] like Figure 2 As shown, the low-voltage busbar incoming line simulates a cable connected to the low-voltage incoming cabinet from the low-voltage side of the transformer. The main meter in the low-voltage metering device measures the power supply of the entire busbar. The low-voltage busbar incoming line is connected to a busbar circuit breaker, which controls whether the busbar is disconnected. The low-voltage busbars from the circuit breaker are equipped with detection and indicating instruments to monitor the voltage, current, and other power consumption information of the low-voltage busbars in real time. The low-voltage busbar has four branch lines. Each branch line is connected to a branch circuit breaker, which controls whether the branch line is disconnected. Each branch line from the circuit breaker is equipped with a branch line detection device to monitor the voltage, current, and other power consumption information of the branch line in real time. Virtual loads are connected below each branch line to simulate the power consumption of users below the branch line.

[0049] like Figure 3As shown, the system control platform can collect electricity consumption information from a new type of power load management and control system simulation platform device, and formulate orderly electricity consumption plans by analyzing the collected electricity consumption information data. The system control platform is connected to the load management terminal via Ethernet communication. The load management terminal can report the collected data to the system control platform and receive control commands from the intermediate system control platform. The load management terminal communicates with the main meter via RS485 communication, and can collect real-time data, historical data, frozen meter codes, and other information from the main meter. The load management terminal also communicates with the bus detection device via RS485 communication, and can collect real-time data, opening and closing status, and other information from the bus detection device. Furthermore, by connecting the load management terminal's cycle control line to the bus detection device, the load control terminal can realize load regulation commands. The system facilitates the relay of load control commands. For example, a remote tripping operation busbar detection device receives tripping commands and cycle control signals from the load management terminal via RS485 communication, controls the busbar circuit breaker to perform tripping operations, and detects the opening and closing status of the busbar circuit breaker. The load management terminal communicates with the branch line detection device via RS485 communication, and can collect real-time data, opening and closing status, and other information from the branch line detection device. Furthermore, by connecting the cycle control line of the load management terminal to the branch line detection device, the system can realize the relay of load control commands from the load management terminal. For example, a remote tripping operation branch line detection device receives tripping commands and cycle control signals from the load management terminal via RS485 communication, controls the branch circuit breaker to perform tripping operations, and detects the opening and closing status of the branch circuit breaker.

[0050] This embodiment, by adding a branch line detection device, can collect power consumption information on the branch side while optimizing load control strategies. Through RS485 communication combined with round-robin control, it prevents malfunctions. By simulating the new power load management system, it can be used to verify the upgrade and transformation of the old power load management system, understand the new power load management system, learn the system's working principles, and formulate orderly power consumption plans.
