IEEE C37.117 – IEEE Guide for the Application of Protective Relays Used for Abnormal Frequency Load Shedding and Restoration
New IEEE Standard – Inactive-Reserved.Information on the application of under frequency load shedding and restoration to ac power systems is compiled in this guide. Various system conditions that may require the use of under frequency load shedding, and the application of protective relays to various methods of performing under frequency load shedding are described in this guide. Some practical examples of under frequency load shedding applications are also provided
