Final answer:
A dispatcher can use a SCADA system to control a power system through monitoring and control functions. For example, they can remotely open or close circuit breakers, switch between power sources, and adjust load distribution. This control capability helps maintain stability and optimize the system's performance.
Step-by-step explanation:
A dispatcher can use a SCADA system to control a power system in two ways: Monitoring: The SCADA system allows the dispatcher to monitor different components of the power system, such as power plants, substations, and transmission lines. The dispatcher can view real-time data, such as voltage and current levels, and identify any abnormalities or issues in the system.
Control: The SCADA system also enables the dispatcher to remotely control various aspects of the power system. For example, they can remotely open or close circuit breakers, switch between power sources, and adjust load distribution. This control capability helps maintain stability and optimize the system's performance.
