SCADA (Supervisory Control And Data Acquisition) system, also known as the data acquisition and monitoring control system. This system is based on computer technology and is a DCS (Distributed Control System) and power automation monitoring system. It has a wide range of applications and can be used in various fields such as data acquisition and monitoring control in power, metallurgy, petroleum, chemical industry, gas, railway, etc., as well as process control in many other areas.
In the power system, the SCADA system is the most widely used and has the most mature technology. It holds an important position in the telecontrol system and can monitor and control the on-site operating equipment to achieve functions such as data acquisition, equipment control, measurement, parameter adjustment, and various signal alarms, which are known as the “four remote” functions. RTU (Remote Terminal Unit) and FTU (Feeder Terminal Unit) are its important components. In the current integrated automation construction of substations, it plays a very important role.
The SCADA (Supervisory Control And Data Acquisition) system involves configuration software, data transmission links (such as radio transceivers, GPRS, etc.)
