SCADA functionality in the power system network improves system stability and reliability for integrated grid operation.
Fremont, CA: Since the introduction of the computer and the internet, machines have begun incorporating computing technology into their systems. This innovation in conventional systems marked the beginning of the industrial revolution's new age. Just like every other system, the electricity system is no different. In recent decades, power networks have developed in response to the needs of investors, users, and operators. Enterprise resource planning technologies have facilitated the automation of power systems. Consequently, electricity systems began using SCADA in the late 20th century.
SCADA for power generation stations
Advanced control structures enable the delivery of the ideal solution for each process involved in power generation operation. In generating stations, the employment of PLCs, robust bus communication links, and SCADA software and hardware oversees several processes, including protection, monitoring, and controlling. In generating stations, the SCADA system is considered as seriously to supply reliable energy, reduce operational costs, and protect capital investments. The SCADA system is also highly efficient for monitoring the Balance of the Plant.
SCADA for power transmission systems
Compared to values measured by the SCADA system, the characteristic of the transmission line circuit model frequently deviates from reality. Without a SCADA system, these errors result in erroneous economic dispatch and, thus, additional costs or improper billing. These mistakes may also impact state estimator analysis, contingency analysis, short circuit analysis, distance relaying, machine stability estimates, and transmission expansion planning. Integration of SCADA into the transmission system is therefore seriously examined.
SCADA for power distribution systems
The distribution of electricity from distribution substations to loads is the responsibility of the power distribution system. Numerous utility businesses rely on physical labor to execute distribution activities such as disconnecting power to loads, hourly monitoring of critical data, etc. Implementing SCADA for electricity distribution eliminates not only manual labor and its associated costs but also promotes uninterrupted operations by minimizing disruptions. SCADA system collects data from numerous electrical substations and processes it accordingly. Substations are equipped with PLCs that continuously monitor the substation's components and relay this data to the central system.
