A. Introduction 1. Title: Frequency and Voltage Protection Settings for Synchronous Generators, Type 1 and Type 2 Wind Resources, and Synchronous Condensers 2. Number: PRC-024-4 3. Purpose: To assure that protection of synchronous generato...
AI summary The document outlines the purpose of PRC-024-4, which is to ensure that the protection settings for synchronous generators, type 1 and type 2 wind resources, and synchronous condensers do not lead to unnecessary tripping during frequency and voltage fluctuations that impact the Bulk Power System (BPS).
9 The figures do not visually represent the "no trip zone" boundaries before 0.1 seconds and after 10,000 seconds. The Frequency Boundary Data Points Table defines the entirety of the "no trip zone" boundaries. 10 Frequency is calculated o...
AI summary The text discusses the calculation of frequency over a time window for trip settings, noting that instantaneous trip settings are not permissible. It references a table defining 'no trip zone' boundaries and mentions a figure illustrating Western Interconnection Boundaries.
PRC-024 — Attachment 2 (Voltage No-Trip Boundaries – Eastern, Western, and ERCOT Interconnections) Figure 5: Voltage No-Trip Boundaries – Eastern, Western, and ERCOT Interconnections
AI summary This document provides a visual representation of voltage no-trip boundaries for the Eastern, Western, and ERCOT interconnections, which are critical for ensuring grid reliability and stability in power systems.
Table 6: High Voltage Boundary Data Points – Quebec Interconnection High Voltage Duration for all Synchronous Generators and Condensers High Voltage Duration for strategic Power Plants Voltage (per unit) Minimum Time (sec) Voltage (per uni...
AI summary The text presents two tables detailing high and low voltage boundary data points for the Quebec Interconnection, including voltage thresholds and minimum durations for synchronous generators, condensers, and strategic power plants. It also references an attachment providing voltage boundary clarifications.
Attachment 2: Frequency Ride-Through Criteria Table 3: Frequency Ride-through Capability Requirements System Frequency (Hz) Minimum Ride-Through Time (sec) > 61.8 May trip > 61.2 299 ≤ 61.2 and ≥ 58.8 Continuous < 58.8 299 < 57.0 May trip...
AI summary Attachment 2 provides frequency ride-through capability requirements for the Bulk-Power System. The table outlines minimum ride-through times for different system frequency ranges, with specific measurements taken at the high-side of the main power transformer.
