Discussion on the Construction of Digital Power Plant

Abstract: The information on the construction of digital power plants is provided by excellent manufacturers of flowmeters and flowmeters. The rapid development of information technology in the 21st century has brought unprecedented opportunities and challenges to China Electric Power. Driven by information technology, the electric power industry, as a national infrastructure industry, is in line with the policy of informatization driving industrialization and industrialization promoting informatization. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is the details of the article discussing the construction of digital power plants. The rapid development of information technology in the 21st century has brought unprecedented opportunities and challenges to China Electric Power. Driven by information technology, the power industry, as a national infrastructure industry,“Informatization drives industrialization, and industrialization promotes informatization”It is transforming from a traditional industry to a highly intensive, highly knowledgeable, and highly technical industry, realizing the modernization of production and operation of power enterprises and the digitization of power management, and informatization is imminent. 1. Overview of Information Technology Development in Thermal Power Plants The informatization of China's power system started in the 1960s, when it mainly focused on automatic monitoring/supervision of power plants and substations. From the 1980s to the 1990s, it began to enter the special business application of the power system, involving the use of systems such as grid dispatch automation, power load control, computer-aided design, and computer simulation. After the 1990s, information technology has been further applied comprehensively. The management information system supported by graphics as the interface, network and database has been gradually promoted in power enterprises, and computer control technology has also been widely used in power plant control systems. , the informatization of the power industry has achieved leapfrog development, and the application of information technology has reached an unprecedented depth and breadth. Although the informatization construction of my country's electric power industry has achieved a certain scale, and the network of electric power enterprises has been generally established, there is still a phenomenon that the computer application system is scattered and information cannot be shared. 2. Discussion on the idea of ​​digital thermal power plant construction 2.1 Digital management Digital management refers to the use of computer, communication, network, artificial intelligence and other technologies to quantify management objects and management behaviors, and realize the management activities of planning, organization, coordination, service, innovation and other functions and management methods in general. Digital management has two basic meanings: one is that the activities of enterprise management are realized based on the network, and the knowledge resources, information resources and wealth of the enterprise can be digitized; sex. 2.2 Discussion on the construction of digital thermal power plant Through the research on the digital management of power generation enterprises and the actual situation of the company, the preliminary idea of ​​gradually building a digital thermal power plant according to the concept of two platforms and three management areas is put forward. The company is a large-scale power generation enterprise. The company has 8 generator sets with a total capacity of 1.2 million kW. (1) Two platforms. 1) The construction and improvement of the network platform. The company's network system was established in 1998, using the backbone 100M Fast Ethernet, and the central switch is BayAccelar1200. With the expansion of network applications, the amount of network information increases rapidly, most network equipment reaches full load, and the 100M backbone network has formed a bottleneck, which seriously restricts the development of the entire information system. In response to the above situation, the company started network transformation in the second half of 2002. In order to ensure the practicability, advancement and consistency of the network, in the renovation project, the backbone network was increased to 1000M, and 100M to the desktop. According to the requirements of the 'Secondary Power System Safety Protection Regulations' promulgated by the State Electricity Regulatory Commission in December 2004, an independent power dispatching data network has been established. The network is based on MPLSVPN technology, uses independent network equipment and dedicated physical channel networking, and is physically isolated from other networks. Due to the scattered office locations of thermal power plants, there are many remote equipment and remote duty points, such as sewage pump houses, heat exchange stations and some tertiary industry companies; at the same time, based on the convenience and flexibility of wireless networks, after comprehensive consideration of cost performance, In October 2003, a wireless local area network was set up as a supplement to the wired network to solve the problem of information islands. With the gradual deepening of network applications, the network security issues in the production area have become increasingly important. In order to further improve network management and fully ensure the absolute security of the production control area, the production area network was isolated separately in 2005 as the basis of the SIS network. SIS system is an independent network integrated by network communication system, server, workstation, storage device, network security device, interface device, operating system, database system, etc. It is a dedicated network operation platform established to realize various functions of SIS. So far, all information points of the company have been classified and networked, the speed of information exchange has been greatly improved, the network operation is safe and reliable, and a stable network hardware platform has been built for the construction of digital power plants.
