The task of power dispatching involves collecting data returned by equipment and monitoring personnel based on a variety of information, combined with the actual working conditions of the power grid, including key parameters such as voltage, current, frequency and load, to comprehensively analyze the progress of production activities. Workers must assess the safety and economic efficiency of the grid and issue instructions through ** or automated systems to guide field workers or automated control systems to make adjustments accordingly. These adjustments may include changing generator outputs, redistributing loads, switching capacitors and reactors on or off, etc., to ensure that the grid can work continuously, safely, and retably.
With the progress of science and technology, modern monitoring and control technology has been continuously improved in recent years, providing more powerful technical support for power dispatching. "Power rationing"It is a safety measure taken when the output of the generator cannot meet the power demand or the transmission and transformation system cannot bear a higher load, and even after adjusting the load distribution, it still cannot meet the operation requirements, that is, cut off part of the load to protect the safety of the power grid or transmission and transformation system.
In the power control system, the installation of industrial TV monitoring system is to improve the speed of emergency response at the critical moment of ensuring power dispatching and power dispatching, so as to further ensure the safety of power management. In addition, dispatchers are responsible for coordinating, organizing, directing, and directing the power grid to keep it running efficiently.
The composition of the power dispatching simulation screen.
Screen: The screen is made of high-quality cold-rolled steel plate and is equipped with a rear dust-proof door to form a completely enclosed structure. It consists of a splicing of individual cell columns with a width of 800 mm. Typically, the width of the left and right bezels is set at 100 mm, the height of the top frame is 100 mm, and the height of the bottom guard is usually between 300 and 600 mm.
The screen is designed as a natural curved standing structure, and its radius of curvature is specially designed according to the size of the installation site. When choosing decorative materials, you can use bare board design to present a simple and solemn appearance; There is also the option of using aluminum alloy or plastic aluminum sheets for decoration, creating a luxurious and elegant feel.
Screen core: The core working area of the analog screen is the screen core, and the information displayed on it is evenly dispersed. The blocks that make up the core of the screen are made of engineering plastics that are fireproof, not easy to fade and have a low deformation rate, which meets the relevant safety standards. The blocks are set at a standard size of 25x25 mm and are equipped with movable movable covers, making it easy to change settings. The entire screen core is assembled from these unit blocks. The power symbols and wiring inside the screen core are pressed with movable cover molds and marked with groove-filled protruding paint. The letter and numeric logos are formed by copy milling and then lacquered, or they can be screen-printed. Elements such as meters and lights are embedded in the screen core.
The screen core can also be designed as a local geographic wiring map of a certain area to visually display the administrative division of the area. These boundaries can be achieved by overmolding or screen printing, while the zones are distinguished by blocks of different colors to create the visual effect of a map. In addition, the location of the individual power stations, their connection to each other, the location and number of switches on the lines, and their operating status can be marked on the diagram.
As for the configuration of the screen controller, it can be selected according to the standard requirements, or customized according to the specific needs of the user. The control of the analog screen is achieved by computer.
The computer is a high-reliability industrial computer or a commercial computer, and the model, brand and configuration will be matched according to the specific needs of the user. Its main function is to receive remote control signals through the communication port or network and perform the corresponding tasks. The company offers a variety of data display options, allowing users to choose the right device for their needs, and these displays can display a variety of information including current, voltage, tap location, active power, reactive power, power factor, and frequency. These data displays are designed based on a microcontroller architecture and are capable of receiving communication data and connecting with an analog screen control system.
Status display: The company has more than a dozen status displays, which mainly display the status of remote signaling information such as line switch status, maintenance status, grounding indication and other remote signal information connected with the analog screen control system.
Time Display:
The company's time displays have a variety of varieties such as clocks, days, and integrated displays, and are of different sizes, which can be used independently or connected with GPS systems.
Power supply: The main function of the drive system that provides energy to all electrical components on the screen.
1. It is connected with telecontrol equipment to realize the communication function of real-time information displayed on the screen.
2. The function of human-computer dialogue.
3. Self-test lamp function.
4. Realize the flashing and multi-level dimming function of the display light.
5. Realize the function of bright disk and dark disk display. Titanium frame.
6. Display power supply power flow, real-time data display, and switch status function.
7. Manually set the position and set the number. When the telecontrol device is deactivated, the data can also be uploaded to the screen.
8. Geographical demarcation display function.
