Description

Technical Field

[0001] The utility model relates to the technical field of power supply remote control, in particular to a shore-based power supply remote power-off and power-off operation device based on modern Internet technology. Background Art

[0002] Generally, ships at port usually use auxiliary engines to generate electricity to meet the power needs of refrigeration, air conditioning, heating, communications, lighting, etc. on board. Usually, the auxiliary engines of ships use diesel generators, which will emit air pollutants such as nitrogen oxides and sulfur oxides in the process of consuming fuel, affecting the environmental quality of the port and the city where it is located.

[0003] As the production scale of ports grows rapidly, the energy consumption and pollutant emissions of ports also increase accordingly. Considering that the traditional power supply method of using diesel engines to power ships has a large impact on the environment, consumes a lot of fuel, is noisy and inefficient, it is considered to use land power to power ships at the port.

[0004] With the maturity of shore power product technology, the application of ship shore power has been widely promoted, and the number and frequency of shore power use in ports have continued to increase. However, since traditional shore power connection and power outage require a lot of manpower coordination and cooperation to complete a ship-to-ship power supply, and the degree of automation and digitization is not high, it brings huge challenges to the use of shore power.

[0005] At present, the shore power technology for ships usually provides power from the shore side, and the power is supplied to the ship side by pulling wires from the shore side. This solution has low reliability, lacks the function of power system protection, and has low safety. When the ship is shaken by waves, strong winds, etc., the cable is easily torn, causing abnormal power consumption on the ship side.

[0006] At present, there are still some deficiencies in the high-voltage shore power remote power supply and shutdown operation system at home and abroad. Since shore power access requires manual cable connection at the front of the wharf, the control room also requires operators to operate the shore power, which requires collaborative operation by multiple people.

[0007] The shore power supply with China's public patent CN220830315U in the existing technology also has defects and deficiencies in remote operation. The current operation method has outstanding problems such as low automation and digitization level, lack of automatic billing function, and limited replicable promotion experience. It cannot fully meet the power outage operation requirements of high-voltage shore power, and further research and improvement are needed. Utility Model Content

The implementation of this system has improved the convenience and reliability of operation, added research on automation and digitalization, reduced the labor cost of operators, and increased operating efficiency by 60%.

At the same time, the data can be uploaded to the data center to improve the efficiency and safety of shore-based power, overcome the key technologies of remote control and data collection, reduce the risk of electric shock, and improve work efficiency.

[0096] The high-voltage shore power remote power outage control system mainly includes the following parts: remote controller, communication processor, data collector, communication module and intelligent shore power management system.

[0097] (1) Add a set of fiber-optic to Ethernet and add a set of fiber-optic network cables to the optoelectronic switch in the control room to realize the function of long-distance information transmission. One end of the newly added optical fiber is connected to the shore power box at the dock, and the other end is connected to the optoelectronic switch in the dock remote control cabinet in the control room. Since the optoelectronic switch is connected to the main controller, but the configuration screen in the column box next to the shore power box at the dock does not have a fiber-optic port, a fiber-optic to Ethernet module is added to the column box next to the shore power box at the dock, and then connected to the configuration screen through a network cable, remote four-remote control can be realized. By designing the main control and configuration program, the technology of remote control of power supply and real-time display of data is realized.

[0098] The photoelectric conversion module includes: an optical fiber port, an electrical signal port, an optical-electrical bidirectional conversion module and a power supply module; the optical-electrical bidirectional conversion module is connected to the optical fiber port, the electrical signal port and the power supply module. The optical fiber port connects the controller to the optical-electrical bidirectional conversion module through an optical fiber, and transmits optical signals between them. The electrical signal port connects the real-time simulation system to the optical-electrical bidirectional conversion module through an electrical signal line, and transmits electrical signals between them. The optical-electrical bidirectional conversion module can convert optical signals into corresponding electrical signals, and can also convert electrical signals into corresponding optical signals. The power supply module supplies power to the optical-electrical bidirectional conversion module.

The real-time system side port is connected to the real-time simulation system to the voltage level conversion module, and the controller side port is connected to the voltage level conversion module to the controller side. After passing through the voltage level conversion module, the input / output signal levels of the real-time simulation system and the controller will be mutually adapted. The power supply module supplies power to the voltage level conversion module.

[0100] (2) Main working principle:

[0101] Sensors and data collection: The sensors in the shore power system are responsible for collecting various data of the power system, including current, voltage, power and other information. These data are transmitted to the main controller through the RS485 communication interface.

[0102] Main controller and data processing: The main controller receives data from sensors and processes and analyzes it. Using preset algorithms, the main controller can monitor the operating status of the power system in real time, including load conditions, voltage stability, etc.

[0103] (3) Remote control and monitoring: The main controller is connected to the monitoring center on shore via optical fiber and 4G signals. The monitoring center can remotely control and monitor the ship's power outage operation. Operators can start and stop power supply through remote control, and monitor the operating status of the power system in real time to ensure the safety and stability of power supply.

[0104] The communication module includes a fiber optic transceiver, an RS485 interface circuit, a switch, etc. The communication processor and the data collector are set on the shore-based power supply to collect the working parameters of the shore-based power supply and control the shore power equipment. The communication processor is connected to the remote controller through the switch and the optical fiber.

[0105] Through the remote controller and communication module, the start and stop of the shore-based power supply can be remotely controlled, and the working status and environmental status of the shore-based power supply can be collected through the added data collector. All data are displayed on the remote touch screen, which is convenient for the staff to understand the operating status of the shore-based power supply in real time, ensuring that the staff can know the situation at the first time when the shore-based power supply has abnormal operation, and respond quickly to prevent larger power supply failures.

[0106] in:

[0107] (1) Main controller and data processing

[0108] Through telemetry and telesignaling, the functions of collecting, processing and outputting power data are realized. Select the distribution monitoring components developed based on microprocessor technology with standard communication interface, which includes measuring the electrical parameters such as the operating voltage and current of the equipment; it can provide comprehensive protection for the equipment, mainly including short circuit, stall, overtime start, phase failure, overload, overvoltage, underload, undervoltage, undercurrent, PTC temperature, grounding, etc.; it supports Modbus_RTU communication protocol, provides RS-485 communication interface, and can realize alarm / protection signal output.

[0109] The data collector is connected to the communication module, one end of the remote controller and the power module is connected to the communication module, the other end of the power module is connected to the controller, and the other end of the remote controller is connected to the cloud server.

[0110] (2) Remote control and monitoring

[0112] Through the remote controller and communication module, the start and stop of the shore-based power supply can be remotely controlled, and the working status and environmental status of the shore-based power supply can be collected through the added data collector. All data are displayed on the remote touch screen, which is convenient for the staff to understand the operating status of the shore-based power supply in real time, ensuring that the staff can know the situation at the first time when the shore-based power supply has abnormal operation, and respond quickly to prevent larger power supply failures.

[0113] Frequency conversion configuration:

[0114] Incoming line cabinet → step-down transformer → power cabinet → isolation transformer → impedance cabinet → outgoing line mother cabinet → outgoing line cabinet → frequency conversion shore power box.

[0115] Fixed frequency configuration:

[0116] Incoming line cabinet→isolation transformer→outgoing line cabinet→inrush current cabinet→constant frequency shore power box.

[0117] (3) Intelligent shore power management system

[0118] The system is built at three levels, namely the perception layer, the network layer and the application layer. It uses 5G+ communication technology and the Modbus protocol to collect shore power data in real time. The system adopts a B / S architecture, which can implement background management and tracking in data centers and other places. At the same time, through the APP, power consumption information can be released to different departments in real time.

[0119] On-site power transmission → shore power system → intelligent data collection gateway → IOT platform;

[0120] The IOT platform also builds WeChat applet and smart shore power system;

[0121] In WeChat Mini Program:

[0122] For the ship, functions such as real-time viewing of meter readings and power consumption record review are configured.

[0123] For the passenger side, functions such as real-time viewing of meter readings, power supply and power-off control, power consumption record review, and abnormal power consumption alarm are configured.

[0124] Configuration functions in the smart shore power system: leadership cockpit, power consumption data generation, automatic cost calculation, abnormal power consumption alarm, custom audit process, multi-dimensional query, customized report, role menu permissions.

[0125] The system can be remotely controlled. When the power supply to the ship in the port is stopped, the shore power data can be monitored at the control box, which is convenient for operation, improves efficiency, and automatically generates electricity billing statistics. At the same time, the data can be uploaded to the data center, overcoming the technical difficulties of being unable to remotely control and collect data.

[0126] Realize remote control of shore power supply interruption:

[0127] To solve the problem that port operators have to walk a long distance to the control room every time to shut down power and read data, a technology based on adding a remote control device next to the shore power box at the dock and reading data is proposed. This technology enables port operators to obtain all data in time and shut down power to the ship next to the shore power box.

[0128] Realize the function of automatically counting shore power consumption data:

[0129] Based on artificial intelligence technology, when the ship uses shore power, shore power data is automatically generated and transmitted to the data center through 5G signals.

[0130] Realized intelligent shore power management system:

[0131] The use of shore power at all berths in the port is summarized in real time, and data is monitored in real time to generate data reports for easy query and statistics and decision-making assistance. At the same time, the ship data is distributed to various departments through the official account for easy billing statistics.

[0132] The system's effectiveness:

[0133] (1) Eliminates the risk of electric shock for operators. By adding a remote operation monitoring system near the shore power box, operators can complete the power outage by clicking on the touch screen without entering the high-voltage shore power control room, avoiding the risk of electric shock caused by direct contact with high-voltage equipment.

[0134] (2) Optimize the operation process. The traditional power outage requires personnel to plug the ship's high-voltage cable into the electrical box, and then the ship's staff will notify whether to shut down the power. Because the control room is far away, a phone call is required to make the notification. This achievement uses remote control. After the personnel plug in the cable, they can directly confirm with the ship's staff under the ship, and the power outage work can be completed directly, which optimizes the original cumbersome operation mode.

[0135] (3) Improved operation efficiency. The control room of the shore power is usually far away from the shore power box. When the operation is tight, there is a shortage of personnel. After plugging the cable, the personnel need to walk to the shore power control room to complete the power supply work. The round trip delays the operation efficiency. This achievement can directly complete the power supply work after plugging the cable through the remote touch screen, which improves the operation efficiency. Each operation can be powered on 20 minutes earlier. Based on an average of 14 ships in the port, the power connection time can be increased by 4.6 hours, the power connection amount can be increased by 1,200 degrees, and the ship's carbon dioxide emissions can be reduced by 191 tons.

[0136] The high-voltage shore power remote power supply and shutdown control system belongs to the field of shore power system control technology, and can be used in container, bulk cargo, passenger and vehicle, and inland port shore power. After the operator connects and removes the high-voltage cable, he can complete the one-button power supply and shutdown work through the nearest touch screen without touching the high-voltage equipment in the distribution room, which reduces the close contact between the operator and the high-voltage equipment, effectively prevents the risk of electric shock during the operation, reduces electrical fires and explosion accidents of high-voltage power equipment, and improves the operation efficiency.

[0137] The layout and use of this system at the terminal solves the risk of electric shock and improves the convenience and reliability of operation. At the same time, it reduces the labor cost of operators. It has great promotion and application value in container, bulk cargo, passenger and vehicle ro-ro and inland port shore power.
