Combination of power system and automation technology application
With the development of technological innovation and the upgrading of power supply systems, the application of power automation system technology has become more and more extensive, and has gradually become a trend. Especially in areas with large demand for electricity and complex grid construction, the application of automation technology is particularly important. With the rapid development of microelectronic technology and power electronic technology, electric drive control has come out of the factory, and all modern production line automation systems of control equipment are difficult to control in the traditional electronic drive (electric drive) work. Therefore, with the improvement of electronic technology and automation technology, the flow of mines, farms, offices and household appliances has been widely used in many fields.
Application of Computer Technology in Electric Power Automation System
Computer control technology has played a vital role in the power system. This is due to the rapid development of computer technology, power automation systems and other important aspects of the new generation, which require power transmission, distribution, and transformation links to support computer technology, which will enable the rapid development of the same power system automation technology. As the information management system of the application of computer technology in the smart grid technology, the intelligent control of the combination of power system automation technology and computer technology is formed, this is one of the most widely used technologies of smart grid technology, and the only one among them is A typical technology covers all aspects of power distribution, power transmission and users, dispatching, and power generation. Among them, substation automation systems, stability control systems, and computer technology have been widely used in the system, and the same timetable, as well as flexible AC power transmission and automation systems. It can now be said that the construction of this digital grid is, to a certain extent, the prototype of the smart grid. In fact, the preparatory work is for the construction of China's smart grid. The typical smart grid smart grid communication technology also requires a lot of computer technology in the construction process. You need real-time, two-way, and reliable functions that require the application of advanced modern network communication technology, and the system is completely dependent on the existence of computer technology. And there is an information management system. It can be said that the application of integrated automation technology in substations and the realization of substation automation rely on implementation to realize the development of modern computer technology for power production. An indispensable and important aspect is automated substations. Relying on computer technology, automated substations have been fully utilized in the process of realizing computers, and secondary equipment will also be integrated, networked, digitized, and fully used instead of power signal computer cables or optical fiber cables. Substation automation, and computer screens and automatic recording, the management and operation of the other two components is to operate and monitor the overall substation automation can be achieved, it is part of the computer automation management.
Dispatching automation application automation is the most important part of the power dispatch automation system . Our country will be divided into five dispatch automations, including the automatic dispatching grid level, and the application of computer technology is inseparable from high to low: State Grid , Regional, provincial, district, and county-level dispatching. The most important part is the computer network system of the power grid dispatching control center. These devices constitute an automated dispatching system connected to the entire combined power grid in a computer system. Other main components include workstations, servers, terminal substation equipment, power generation in the field of dispatching large-screen display shields, and printing equipment. Computer dispatch not only has the function of automation to achieve the safe operation of monitored power grid analysis, but also realizes real-time data collection, and also realizes functions such as power system load forecasting and state estimation. So, all kinds of these are measurement and control, and the lower power consumption control center and other equipment pass the dedicated WAN link of the power system.
Application of PLC Technology in Power System Automation
PLC is a combination of computer technology and control technology. Each relay contact uses a programmable memory to store, calculate, record and other operating instructions to achieve control. The technology is designed to use programmable logic controller systems in industrial environments and designs. This technology is widely used. In recent years, power system automation has solved the traditional control system, the complexity of wiring, poor flexibility and low reliability of the shortcomings of energy.
Data processing PLC programmable controller technology can complete data collection, analysis and processing, with sorting, search, mathematical operations, data conversion, data transfer and bit manipulation functions. The available communication function sends these data to other smart devices, and the control operation can be realized, compared with the reference value stored in the memory, or printed out and tabulated. The data can be used in process control systems, as well as flexible manufacturing systems that are generally used in large-scale control systems, such as unmanned control. Continuous PLC control technology, as well as the continuous deepening of reforms, are gradually improving. In recent years, the country’s energy saving and emission reduction requirements have been upgraded to the original relay controller PLC control system for large-scale thermal power plants . The industry reduces resources in the production process. Consumption and improvement of efficiency have become the ultimate goal of every enterprise's management. Therefore, with the advancement of science and technology, automation and control-related business support similar workshop-level power plants have also put forward higher requirements. The use of PLC control systems can be individually controlled, only through the process of information modules, and can be connected to the entire plant. Communication bus coordination.
