Planning and Operational Studies Requirements for all IBRs (completion: November 4, 2026). Reliability Standards PRC-024-4 and PRC-029-1 relate to Generator Ride-through and are part of Milestone 2. Reliability Standard PRC-029-1 establish...
AI summary The document outlines the requirements for Planning and Operational Studies for Inverter-based Resources (IBRs) under Reliability Standards PRC-024-4 and PRC-029-1. These standards focus on generator ride-through performance, ensuring IBRs maintain reliability during disturbances and defining criteria for synchronous generators and wind units.
4.1. Functional Entities: - 4.1.1. Generator Owners that apply protection listed in Sections 4.2.1 or 4.2.2. - 4.1.2. Transmission Owners that apply protection listed in Section 4.2.2. - 4.1.3. Transmission Owners (in the Quebec Interconne...
AI summary This section outlines the functional entities involved in applying protection measures, including Generator Owners, Transmission Owners, and Planning Coordinators, specifically within the Quebec Interconnection. These entities are responsible for implementing protections as detailed in various sections of the document.
- 3.1. The Generator Owner and Transmission Owner shall communicate the documented regulatory or equipment limitation, or the removal of a previously documented regulatory or equipment limitation, to its Planning Coordinator and Transmissi...
AI summary This section outlines requirements for Generator Owners and Transmission Owners to document and communicate equipment or regulatory limitations and protection settings. They must notify Planning Coordinators and Transmission Planners within 30 days of identifying or removing such limitations and provide protection settings within 60 days of a request.
Evaluating Protection Settings: The voltage values in the Attachment 2 voltage boundaries are voltages at the high-side of the GSU/MPT. For resources with multiple stages of step up to reach interconnecting voltage, this is the high-side o...
AI summary The document outlines procedures for evaluating protection settings, focusing on voltage measurements at the high-side of the GSU/MPT. It emphasizes considering voltage differences, loading conditions, and transformer tap settings when using steady-state calculations or dynamic simulations.
Evaluating Protection Settings: The voltage values in the Attachment 2A voltage boundaries are voltages at the high-side of the GSU/MPT. For resources with multiple stages of step up to reach interconnecting voltage, this is the high-side...
AI summary The document discusses evaluating protection settings for electrical systems, focusing on voltage values at the high-side of the GSU/MPT and conditions to consider when using steady state calculations or dynamic simulations for accurate evaluation.
Violation Severity Levels Violation Severity Levels R # Lower VSL Moderate VSL High VSL Severe VSL R1. The Generator Owner failed to ensure the design capability of each applicable IBR to Ride-through in accordance with Attachment 1, excep...
AI summary The document outlines violation severity levels related to the design capability of Inverter-based Resources (IBR) in adhering to ride-through and performance requirements during voltage excursions. Specific violations are categorized under Lower, Moderate, High, and Severe VSL based on the Generator Owner's failure to ensure compliance with specified requirements.
