SCADA
SCADA is an acronym for “Supervisory Control and Data Acquisition”.
SCADA generally refers to an industrial computer system that monitors and controls a process.
SCADA in POWER System
Monitor Substations, Transformers and other electrical assets.
Control geographically dispersed assets that are often scattered over thousands of square kilometres.
Control Power Grids
Power System Load
The main aspect to be considered for a good operation of a grid.
Generation planning and forecasting is essential task.
Centralize generation facilities with a reasonable size with a controller.
Hydro power plants, Wind power plants.
System Adequacy
The capacity of the production units in the power system to cover the demand (load).
The ability of the transmission system to transport the power flows between the generator units and the consumers.
And finally…
The given economic, social and quality-of-life aspects and the interdependencies among infrastructures call for a modern power grid with an upgraded SCADA system.
A continuous improvement of SCADA functions, mainly on the automatic voltage and generation control is imposed. Implementations of load frequency control, as a key component of the SCADA system in the Romanian Power System.
The usage of synchronized SCADA/PMU data is one of the most powerful tools for wide-area monitoring and control since it uses current system conditions to predict potential problems ahead of time.
