Case Study - Consolidating Monitoring With Protection

Today’s disturbance monitoring and reporting requirements provided by FERC, NERC, or individual regional reliability organizations are typically defined by PRC-002-2 for bulk electric system (BES). Similarly, PRC-028-1 defines monitoring and reporting requirements for invertor-based resources. This paper will discuss the similarities and differences between PRC-002-2 and PRC-028-1. With advancements in todays' technology, one can argue the benefits of consolidating monitoring and protection to be able to meet the above monitoring and reporting requirements. This paper will discuss a case study of including monitoring within protection and control devices to meet these requirements. These requirements include minimum sampling rate, fault and disturbance record lengths, sequence of event record lengths, time synchronization and continuous record length.
