What is the difference between the power monitoring background system and the power integrated automation system. The
integrated automation system is to combine and optimize the secondary equipment of the substation (including instrumentation, signal system, relay protection, automatic device and remote control device) through functional combination and optimization design, and use advanced Computer technology, modern electronic technology and communication equipment and signal processing technology can realize the automatic monitoring, measurement, automatic control and microcomputer protection of the main equipment and transmission and distribution lines of the whole substation, as well as comprehensive automation functions such as communication with dispatching.
The principle of the realization of integrated automation.
One is the use of automation systems in low- and medium-voltage substations in order to better implement unattended operations and achieve the purpose of reducing personnel and increasing efficiency; second, it is a requirement for the construction and design of high-voltage substations (220kV and above) Use advanced control methods to solve the problem of dispersing and self-contained systems in various disciplines, repeating investment and even affecting operational reliability.
The power monitoring system uses computers, communication equipment, and measurement and control units as basic tools to provide a basic platform for real-time data acquisition, switch state detection and remote control of the power distribution system. It can form an arbitrarily complex monitoring system with detection and control equipment. It plays a core role in the monitoring of power transformation and distribution, which can help enterprises eliminate islands, reduce operating costs, improve production efficiency, and speed up the abnormal response speed in the process of power transformation and distribution.
Substation integrated
substation integrated automation system is the use of advanced computer technology, modern electronic technology, communication technology and information processing technology to achieve substation secondary equipment (including relay protection, control, measurement, signal, fault recording, automatic devices and remote It is a comprehensive automation system that recombines and optimizes the functions of power devices, etc., and monitors, measures, controls, and coordinates the operation of all equipment in the substation. Through the mutual exchange of information and data sharing among the equipment in the integrated automation system of the substation, the task of monitoring and controlling the operation of the substation is completed. The integrated automation of the substation replaces the conventional secondary equipment of the substation and simplifies the secondary wiring of the substation. Integrated substation automation is an important technical measure to improve the safe and stable operation of substations, reduce operation and maintenance costs, improve economic benefits, and provide users with high-quality electric energy. The integration of functions is the biggest feature that distinguishes it from conventional substations. It is based on computer technology, uses data communication as the means, and takes information sharing as the goal. Basic features
1) The function is integrated. The integrated automation technology of substation is developed on the basis of microcomputer technology, data communication technology and automation technology. It integrates all the secondary equipment in the substation except the primary equipment and AC and DC power supplies.
2) The system is modularized. The digitization of protection, control, and measurement devices (implemented by a microcomputer with digital communication capabilities) facilitates the connection of various functional modules through a communication network, and facilitates the expansion of interface functional modules and the sharing of information. In addition, the modular structure facilitates the configuration of integrated automation system modules in the substation to adapt to the centralized, decentralized, and distributed structure of the project.
3) Structure distribution, stratification and decentralization. The integrated automation system is a distributed system, in which subsystems such as microcomputer protection, data acquisition and control, and other intelligent equipment are designed in a distributed structure. Each subsystem may have multiple CPUs to perform different functions. The CPU group constitutes a complete, highly coordinated organic integrated system.
4) Operation monitoring screen. After the integrated automation of the substation is achieved, whether it is manned or unattended, the operators are either in the substation, in the main control station, or in the main control station or dispatching room, facing the color screen display, to the equipment and transmission lines of the substation. Carry out all-round monitoring and operation.
5) Localization of communications and fiber optic cables. Computer local area network technology and optical fiber communication technology are widely used in integrated automation systems.
6) Intelligent operation management. Intelligence is not only manifested in the conventional automation functions, but also in the ability to perform online self-diagnosis and send the diagnosis results to the remote host.
7) Digital measurement and display. Using a microcomputer monitoring system, conventional pointer instruments are replaced by CRT displays. Manual transcription of records is replaced by printers.
