SynchroGrid possesses depth of experience and unique system protection expertise. These vital characteristics give us a high-quality understanding of all the NERC Protection and Control standards. SynchroGrid's engineers also strive for excellent writing skills, which are critical for NERC document preparation.


SynchroGrid can aid utilities preparing for NERC auditing by providing technical information for the following standards:

  • PRC-002: Disturbance Monitoring and Reporting Requirements
  • PRC-005: Protection System, Automatic Reclosing, and Sudden Pressure Relaying Maintenance
    • SynchroGrid has developed a step-by-step procedure tailored to each generator which examines the entire system as compared to a generic system test that may only cover small portions of the equipment and may not take your specific requirements into consideration. The three core processes to SynchroGrid's maintenance procedures include relay procedures, functional procedures, and equipment procedures. Having a detailed set of standard procedures will ensure testing consistency between different contractors, with full compliance and documentation for PRC-005.
  • PRC-019: Coordination of Generating Unit or Plant Capabilities, Voltage Regulating Controls, and Protection
    • Using generator data, relay settings, and system information, SynchroGrid graphically plots the exact location of the limit functions, equipment capabilities, and system settings. This assessment displays the precise positioning of the functions to ensure they are concurrent. 
  • PRC-024: Generator Frequency and Voltage Protective Relay Settings
    • SynchroGrid can provide support in assessing standards compliance, implementing solutions, identifying weak areas, and delivering technical and procedural solutions for system protection and standardization to meet PRC-024 reliability standards. We can help create, support, and recommend improvements to the system such that generating units remain compliant to the defined frequency and voltage deviations outlined by this NERC standard.
  • PRC-025: Generator Relay Loadability
    • SynchroGrid offers an automated solution for all users that reduces time spent in fulfilling PRC-025 requirements and in documenting and demonstrating compliance. By combining our expertise in system protection analyses, applying progressive modeling and simulation features using ASPEN or CAPE along with other tools developed in-house, SynchroGrid can offer a well-designed solution to meet PRC-025 requirements.
  • PRC-027: Coordination of Protection System Performance During Faults
    • Utilizing a tool developed in-house called the Settings Automation Relay Assistant (SARA), SynchroGrid offers an automated solution to comply with PRC-027 requirements. SARA provides a settings development process, automates relay settings development, and exports proper documentation of NERC compliance by coupling with ASPEN or CAPE. This solution take advantage of these programs to automate compliance requirements and avoid laborious manual calculations. 

 

SynchroGrid can also aid in complying with the following NERC standards:

  • PRC-001: System Protection Coordination
  • PRC-004: Analysis and Mitigation of Transmission and Generation Protection System Mis-Operations
  • PRC-006: Automatic Underfrequency Load Shedding
  • PRC-008: Implementation and Documentation of Underfrequency Load Shedding Equipment
  • PRC-010: Technical Assessment of the Design and Effectiveness of Undervoltage Load Shedding Program
  • PRC-011: Undervoltage Load Shedding System Maintenance and Testing
  • PRC-015: Special Protection System Data and Documentation
  • PRC-016: Special Protection System Mis-Operations
  • PRC-017: Special Protection System Maintenance and Testing
  • PRC-018: Disturbance Monitoring Equipment Installation and Data Reporting
  • PRC-021: Undervoltage Load Shedding Program Data
  • PRC-022-1: Undervoltage Load Shedding Program Performance
  • PRC-023-2: Transmission Relay Loadability
