Anonymous users2024-02-03The basic principle of China's power grid dispatching automation is to use modern automation technology to mobilize the power grid. Including the telecontrol device and the dispatching master station system, it is used to monitor the operation status of the entire power grid. In order to enable the dispatcher to take a holistic view of the overall situation, plan the whole network, and effectively command the safety and stability of the power grid.
Now that the country is developing a smart grid, you can check it!!
China's dispatching situation: five-level hierarchical dispatching management National dispatching and control center - national dispatching regional power grid dispatching and control center - network dispatching and control center Provincial power grid dispatching and control center - provincial dispatching and municipal power grid dispatching and control center - local dispatching county-level power grid dispatching and control center - county dispatch.
Basic principles of scheduling: unified scheduling, hierarchical management, hierarchical control.

Anonymous users2024-02-02Answer: The basic structure of the power grid dispatching automation system includes three parts: the control center, the master station system, the plant station end (RTU) and the information channel. According to the different functions completed, this system can be divided into information acquisition and execution subsystem, information transmission subsystem, information processing subsystem and human-machine contact subsystem.
The basic function of the information acquisition and execution subsystem is to collect various real-time information that characterizes the operation status of the power system in various power plants and substations. In addition, the system is responsible for receiving and executing operation, regulation or control commands issued by the higher-level dispatch control center.
The information transmission subsystem provides a bridge for information exchange between the information acquisition and execution subsystem and the dispatching control center, and its core is the data channel, which is connected to the RTU and the master front-end processor through the modem.
The information processing subsystem is the core of the whole dispatching automation system, with the electronic computer as the main component. The subsystem contains a large number of computer application software directly for power grid dispatching and operation personnel, which completes various processing and analysis calculations of the collected information, and even realizes the automatic control and operation of power equipment.
The man-machine contact subsystem will process all kinds of information transmitted to the dispatching control center, and provide complete and practical real-time information of the power system for dispatchers through various display devices, printing equipment and other output devices. The remote control and remote adjustment instructions issued by the dispatcher are also input through this system and transmitted to the actuator.

Anonymous users2024-02-01Briefly describe the meaning and content of power system automation.
Answer: The automation of the power system is based on the unique law of the power system itself, the application of the principle of automatic control, and the use of automatic control devices to automatically realize the safe and reliable operation of power production.
That is, the application of a variety of instruments and devices with automatic detection, feedback, decision-making and control functions, through the signal system, data transmission system to the power system components, local system or the whole system of local or remote automatic monitoring, coordination, regulation and control, in order to ensure that the power system has qualified power supply quality and safe and economical operation.
Purpose: to ensure the safe and reliable operation of the power system, reduce human labor intensity, and improve production efficiency.
Power system automation is also a specific form of automation.
The main contents of power system automation are: power system dispatching automation, power plant automation, distribution automation, substation automation, that is, power system automatic monitoring and control system, power plant power machinery automatic control system, substation automatic control system, power system automatic device system.
In tunnel construction, in addition to increasing the working face by excavating the flat ridge and inclined shaft, the method of excavating the shaft can also be used to increase the working face, and the whole tunnel is divided into several sections, and the sectional excavation is carried out. For example, in the construction of urban underground railways, each underground station is a large shaft, which is excavated with a shield between the stations, and is not affected by the dense buildings and heavy traffic on the urban ground. >>>More

The first book is about Gulliver's encounter in Lilliputia, where Gulliver has a ratio of twelve to one in size, where the inhabitants are only 6 inches tall, and Gulliver is in it like a "mountain of giants". At first he was tied up by the villains, but later, due to his meekness and promise to accept certain conditions, the Lilliputian king agreed to restore his freedom. At this time, the country was being invaded by another Lilliputian (Blefscu), and Gulliver waded across the Channel to capture most of the ships of the enemy fleet, forcing the enemy to send an envoy to sue for peace. >>>More
