Advanced Topics in Power System Protection
Advanced study of how protection, control, monitoring, and communications are converging in modern substations. The course traces the progression from electromechanical and static relays to multifunction digital relays and examines the measurement, logic, communication, automation, and system-level capabilities shaping future protection schemes.
Objectives
- Explain the operating pressures and technology changes driving the evolution of power-system protection and control.
- Compare electromechanical, static, and microprocessor-based relay technologies.
- Describe how modern relays combine protection, control, monitoring, metering, recording, and communications.
- Relate digital measurements, phasor calculations, programmable logic, and communications to relay operation.
- Assess the roles of synchronized measurements, digital substations, process-bus architectures, and asset monitoring.
- Identify engineering, testing, maintenance, interoperability, and cybersecurity considerations for future protection systems.
Modules
Description: Examines growing demand, renewable and distributed resources, aging infrastructure, safety, and outage costs as drivers for new protection and control architectures. It surveys digital primary equipment, integrated monitoring, synchrophasors, communication-enabled automation, and the changing role of protection across generation, transmission, distribution, and customer systems.
Description: Develops the progression from single-function electromechanical relays through static designs to multifunction microprocessor-based relays. Topics include digitizing current and voltage inputs, real-time phasor calculation, protection elements and operating characteristics, programmable logic, event recording, metering, synchrophasors, communications, and remote engineering access.
