Wide-Area Monitoring and Control - Automated Control Functions

WAMACS Automated Control describes a set of functions that are typically automated within a substation, but are not directly associated with protection, fault handling, or equipment maintenance. In general, they serve to optimize the operation of the power system and ensure its safe operation by preventing manually generated faults. These functions include:
• Changing transformer taps to regulate system voltage
• Switching capacitor banks or shunts in and out of the system to control voltage and reactive load
• Interlocking of controls to prevent unsafe operation • Sequencing controls to ensure safe operation
• Load balancing of feeders and transmission lines to reduce system wear and resistive losses doc
• Restoring service quickly in the event of a fault, with or without operator confirmation
