What is scada system

SCADA (Supervisory Control And Data Acquisition) system is a data acquisition and supervisory control system. The SCADA system is a computer-based DCS and power automation monitoring system; it has a wide range of applications and can be used in many fields such as data collection and monitoring control and process control in the fields of electric power, metallurgy, petroleum, chemical industry, gas, and railways.

#In the power system, the SCADA system is the most widely used and the technology development is also the most mature. (Recommended learning: PHP video tutorial)

It plays an important role in the telecontrol system and can monitor and control on-site operating equipment to achieve data collection, equipment control, and measurement. , parameter adjustment and various signal alarms and other functions, which are what we know as the "four remote" functions. RTU (Remote Terminal Unit) and FTU (Feeder Terminal Unit) are its important components. It plays a very important role in the current comprehensive automation construction of substations.

SCADA system, that is, data collection and monitoring control system, involves configuration software and data transmission links (such as data transmission radio stations, GPRS, etc.)

SCADA system is a computer-based production process control and scheduling automation system. It can monitor and control on-site operating equipment.

Since various application fields have different requirements for SCADA, the development of SCADA systems in different application fields is not exactly the same.

SCADA systems are most widely used in power systems and have the most mature technology development. As the most important subsystem of the energy management system (EMS system), it has the advantages of complete information, improved efficiency, correct control of system operating status, accelerated decision-making, and can help quickly diagnose system fault conditions. It has become an indispensable part of power dispatching. Missing tools. It plays an irreplaceable role in improving the reliability, security and economic benefits of power grid operation, reducing dispatchers' needs, realizing the automation and modernization of power dispatching, and improving the efficiency and level of dispatching.

SCADA has been applied earlier in railway electrification telecontrol systems, and has played a great role in ensuring the safe and reliable power supply of electrified railways and improving the dispatching and management level of railway transportation. In the development process of railway electrification SCADA systems, with the development of computers, there are different products in different periods. At the same time, our country has also introduced a large number of SCADA products and equipment from abroad. These have driven the railway electrification telecontrol system to a higher level. Goal development.

The SCADA system is constantly being improved and developed, and its technological progress has never stopped for a moment. Today, with the increasing demand for SCADA systems from power systems and railway electrification systems and the development of computer technology, new requirements are put forward for SCADA systems.
