Achieving compliance with North American Electric Reliability Corporation (NERC) requirements takes knowledge of ever-changing and complex regulations. These regulations require utilities and similar facilities to implement an ongoing, systematic program to test, maintain, and document the performance of protection scheme devices that impact the Bulk Electric System (BES).
Vertiv’s NERC compliance services provide generator and transmission owners and operators with the resources and tools needed to address reliability requirements. Our compliance experts leverage in-depth understanding of NERC standards and how they impact power-producing infrastructure to help you develop a compliance program.
The first step to achieving compliance is to determine your current status. To get started, Vertiv™ engineers have developed a downloadable tool that allows you to quickly assess the settings for your facility’s generator unit protection relays and determine if they meet PRC-025-1 requirements, and if not, by what margin. The results from this assessment will determine the level of effort required to demonstrate compliance or if additional actions must be taken to meet requirements.
Engineering Analysis and Modeling
Evaluation of your infrastructure involves on-site data analysis and data collection by our highly-trained engineers who have years of experience working in and around operating generation plants. They ensure that the right data is collected in the most efficient manner possible. Once the data is collected, they will assemble and organize it to perform modeling and an engineering analysis of your electrical system. Whether your generation unit is evaluated under field forcing simulations using power system modeling software or by conservative loadability evaluation criteria, a complete NERC-approved mathematical proof will be provided for each load sensitive relay requiring study. Our engineers leverage industry accepted software applications to model dynamic systems including PSSE, E-Tap, MatLab and Power World. Upon completion of the analysis, a comprehensive report will be provided with recommendations and corrective actions required for ensuring compliance and improving power system loadability at your facility.
NERC Program Management
Implementing corrective actions is the next step to ensuring compliance. Vertiv’s NERC program management services provide ongoing support throughout the compliance process. From identification of non-compliance issues to project planning and management, we will be with you every step of the way helping you select the most cost effective and appropriate solutions. You can rest assured, knowing that you will have expert engineering assistance to selectively coordinate the proposed protective device settings with your utility and the field resources needed to implement and test relay settings changes. Whether you are operating a single combustion unit or you own a hundred sites, we have the resources to ensure that your scope of work is completed on schedule. Our engineers are sensitive to the deadlines that accompany NERC implementation plans and will work to ensure that your fleet will complete the requirements on time, avoiding a self-report situation.
In some cases, the existing protective devices may not be capable of accepting the settings required to comply with loadability requirements. In this situation, it may be necessary to retrofit, upgrade, or replace the existing relays with microprocessor-based relays capable of providing the appropriate protection while maintaining system stability during disturbance events. We can provide turnkey relay replacement solutions for these unique situations, including engineering, procurement, installation, testing, startup and commissioning. Under these circumstances NERC allows a two-year extension for compliance until October 2021.
NERC Compliance Documentation
After compliance has been verified, a technical report is provided to demonstrate compliance. Our NERC conformance reports are designed with the auditor’s needs in mind. Using standardized terminology and equations from the NERC standards ensures clear interpretation of the results. To support a successful audit, reports include comprehensive engineering analysis that is searchable and linked for ease of navigation and full demonstration of compliance. Lastly, each report is a “living” document allowing for recently updated or cyclic information, such as relay
