What does PRC-005 pertain to in grid operation?

• A. Protection system settings.
• B. Interconnection of distributed resources.
• C. Cyber security governance.
• D. Substation communications protocols.

Answer: (A)

This standard focuses on Protection System Settings. In grid operation, protective relays and other protective devices must be configured so they trip only the intended part of the network during faults, providing fast and selective clearance without unnecessarily interrupting healthy sections. PRC-005 governs how those protection settings are developed, documented, tested, and maintained, and how they’re updated when equipment or system topology changes. It emphasizes coordination between devices so protection zones operate in the correct sequence, ensuring reliability and stability. The other topics lie outside this standard’s scope: interconnection of distributed resources is about integrating DERs, cyber security governance is covered by other standards, and substation communications protocols fall under different areas of practice.
