TPL-007 establishes planning criteria for induced currents caused by geomagnetic disturbances. The standard is applicable to facilities using transformer(s) with a high side, wye grounded winding operated above 200 kV and can require both submittal of general geomagnetic data (R2) and thermal impact assessments (R6) depending on results of Planning Coordinator analysis.
VAR-501-WECC requires applicable entities within the WECC region to confirm performance settings and characteristics of Power System Stabilizers (PSS). NAES provides physical testing and reporting services to address WECC’s specific PSS requirements.
PER-006 requires Generator Operators to provide training to personnel who are responsible for the Real-time control of a generator. NAES has developed specific protection system training materials suitable for compliance with the Standard and provides this training both on and off site
PRC-001 requires entities to coordinate protection system changes with other affected parties. NAES offers both procedural documentation and engineering services to establish the required coordination for both PRC-001 and PRC-027.
PRC-002 requires the installation and operation of disturbance monitoring equipment (DME) for applicable entities. NAES can assist with the design and installation of DME as well as ongoing compliance support.
PRC-019 requires applicable entities to show coordination between voltage regulating controls, limiters, equipment capabilities, and protection settings. NAES produces PRC-019 specific coordination studies for both traditional generators and renewable projects to establish compliance with the Standard.
PRC-023 requires load responsive protective relays be set according to criteria within the Standard to ensure settings do not limit transmission loadability. NAES provides full engineering analyses to maintain compliance with this Standard.
PRC-024 requires applicable entities to ensure generator protective relays do not trip within predefined frequency and voltage limits. NAES can complete protection settings analyses and provide compliance documentation that clearly identifies protection settings as they relate to NERC’s “no trip” zones.
PRC-025 establishes minimum settings requirements for load-responsive relays protecting generators, step up transformers, and auxiliary transformers. NAES utilizes predefined calculation options as well as simulations to determine a facility’s compliance status and development of new relay settings if required.
PRC-026 requires applicable entities to perform load responsive relay settings analyses based on criteria identified within the Standard. Entities are typically notified by the Planning Coordinator when an analysis is required. NAES performs all required studies to establish compliance.
MOD-025 requires Real and Reactive Power capability testing for individual generating units over 20 MVA or facilities with over 75 MVA of generation capacity. NAES offers site specific test procedures and/or complete onsite testing services to meet the requirements of this standard.
MOD-026 requires verification of excitation or volt/var control dynamic models through utilization of either system disturbances or physical testing. NAES offers full testing and modeling services to meet the requirements of this standard.
MOD-027 requires verification of governor or active power/frequency control dynamic models through utilization of either system disturbances or physical testing. NAES offers full testing and modeling services to meet the requirements of this standard.
