The application in hydropower plant improves the automation efficiency of hydropower plant, saves energy, reduces the operation energy consumption of hydropower plant and reduces pollution. At the same time, the monitoring system of hydropower plant is more professional and systematic, and the monitoring scope is expanded.
2. The application of thermal power plant
Electric power automation technology is also widely used in electric power. For example, MOS controlled thyristor can integrate drive circuit, overvoltage protection, power detection and so on. Realize the integrated operation of electrical automation. It can also realize AC speed regulation. Electrical automation technology not only improves the working efficiency of power plants, but also reduces the operating cost, making the application of electrical automation more comprehensive and developing faster. In thermal power plants, electrical automation technology has also been widely used, such as monitoring function and signal alarm function, which makes the connection between signals and main signals more convenient, simplifies network communication, increases the convenience of network communication, expands the convenience of network communication and promotes the development of thermal power plants.
3. Application in building electricity
In architecture, electrical automation plays an extremely important role, which can make the control system in architecture safer, more scientific and more intelligent. Its application mainly includes two aspects: (1)TN-S system, and the corresponding substation is set in the building, which improves the reliability of the building power system. (2)TN-C-S system consists of two grounding systems, including TN-C system and TN-S system, and the connection point between N line and PE line is the interface. This system can improve the safety and reliability of building power system and make the management of power system more comprehensive and scientific.
4. Application in substation
The application of substation electrical automation is of great significance, which can replace manual operation monitoring of equipment, thus improving the efficiency of equipment monitoring, better improving the operation speed of substation and promoting the development of power engineering. Through the application of electrical automation, we can master the electrical equipment in all directions, track the operation of the equipment in real time, monitor the operation state of the equipment, find various problems and defects of the equipment in time, and ensure the operation efficiency and quality of the substation. Most importantly, electrical automation can realize automatic operation through data transmission, which effectively promotes the development of power economy.
5. The application of transfer dispatching applies electrical automation to power dispatching, which can effectively connect all parts together, provide convenience for power grid dispatching and promote the systematic operation of power grid dispatching. Accurately grasp the operation situation in power grid dispatching, strengthen data analysis and detection, collect and track data in real time, conduct comprehensive monitoring, improve the safety of power grid dispatching, and contribute to promoting the national economy.
Third, the future development trend of electrical automation in power engineering
1. Digital technology is a new technology with high technical content, strong logic and simple operation. With the integration of electrical automation technology, the application of digital technology in power engineering production can realize signal simulation, so as to carry out fault diagnosis and error information diagnosis and reduce the mistakes in the operation of electrical equipment.
2. In order to meet the communication needs between departments and industries, it is necessary to realize the integration of data control and monitoring with the help of integrated automation system, which has comprehensively improved the protection and control level of high-voltage system. The integrated automation system can detect the status and faults of all kinds of equipment under the control of computer, and transmit signals in time.
3. In order to promote the better development of electrical automation technology, it is necessary to increase the innovation of intelligent terminal technology, realize the connection between devices by using optical fiber, make different devices cooperate with each other, and comprehensively improve the work quality of power engineering. For example, double devices can be used, one device is responsible for power-off protection and the other device is responsible for trip protection, so as to comprehensively improve the reliability of industrial electrical automation technology application and maximize economic benefits.
With the progress of science and technology and the improvement of people's quality of life, electrical automation technology has been widely used. Under the background of diversified times, it is still necessary to carry out technological innovation and expand the application scope of electrical automation technology. Only by strengthening the innovation of electrical automation technology can we better promote the development of electric power economy and further promote the development of national economy.
