PRC-018-1: Disturbance Monitoring Equipment Installation and Data Reporting

Purpose
Ensure that Disturbance Monitoring Equipment (DME) is installed and that  Disturbance data is reported in accordance with regional requirements to facilitate analyses of events.

Applicability

  • Transmission Owner.
  • Generator Owner.

Effective Dates
Phased in over four years after BOT adoption:

Requirements 1 and 2:

    • 50% compliant two years after initial issuance of regional requirements per RELIABILITY STANDARD PRC-002 Requirement 5.
    • 75% compliant three years after initial issuance of regional requirements per reliability standard PRC-002 R5.
    • 100% compliant four years after initial issuance of regional requirements per reliability standard PRC-002 R5.

Requirements 3 through 6:

    • 100% compliant six months after BOT adoption for already installed DME.
    • 100% compliant six months after installation for DMEs installed to meet Regional Reliability Organization requirements per reliability standard PRC-002 Requirements 1, 2 and 3.

Requirements
R1. Each Transmission Owner and Generator Owner required to install DMEs by its Regional  Reliability Organization (reliability standard PRC-002 Requirements 1-3) shall have DMEs installed that meet the following requirements:

R1.1. Internal Clocks in DME devices shall be synchronized to within 2 milliseconds or less of Universal Coordinated Time scale (UTC)

R1.2. Recorded data from each Disturbance shall be retrievable for ten calendar days..

R2. The Transmission Owner and Generator Owner shall each install DMEs in accordance  with its Regional Reliability Organization’s installation requirements (reliability standard PRC-002 Requirements 1 through 3).

R3. The Transmission Owner and Generator Owner shall each maintain, and report to its Regional Reliability Organization on request, the following data on the DMEs installed to meet that region’s installation requirements (reliability standard PRC-002 Requirements1.1, 2.1 and 3.1):

R3.1. Type of DME (sequence of event recorder, fault recorder, or dynamic disturbance  recorder).

R3.2. Make and model of equipment.

R3.3. Installation location.

R3.4. Operational status.

R3.5. Date last tested.

R3.6. Monitored elements, such as transmission circuit, bus section, etc.

R3.7. Monitored devices, such as circuit breaker, disconnect status, alarms, etc.

R3.8. Monitored electrical quantities, such as voltage, current, etc.

R4. The Transmission Owner and Generator Owner shall each provide Disturbance data (recorded by DMEs) in accordance with its Regional Reliability Organization’s requirements (reliability standard PRC-002 Requirement 4).

R5. The Transmission Owner and Generator Owner shall each archive all data recorded by DMEs for Regional Reliability Organization-identified events for at least three years.

R6. Each Transmission Owner and Generator Owner that is required by its Regional Reliability Organization to have DMEs shall have a maintenance and testing program for those DMEs that includes:

R6.1. Maintenance and testing intervals and their basis.

R6.2. Summary of maintenance and testing procedures.

Measures
M1. The Transmission Owner and Generator Owner shall each have evidence that DMEs it is  required to have meet the functional requirements specified in Requirement 1 and are installed in accordance with its associated Regional Reliability Organization’s requirements (R2).

M2. The Transmission Owner and Generator Owner shall each maintain the data listed in Requirements 3.1 through 3.8 for the DMEs installed to meet its Regional Reliability Organization’s DME installation requirements.

M2.1 The Transmission Owner and Generator Owner shall each have evidence it provided this DME data to its Regional Reliability Organization within 30 calendar days of a request.

M3. The Transmission Owner and Generator Owner shall each have evidence it retained and provided recorded Disturbance data to entities in accordance with its associated Regional Reliability Organization’s Disturbance data reporting requirements. (R4 R5)

M4. Each Transmission Owner and Generator Owner that is required to install DMEs to meet its Regional Reliability Organization’s DME installation requirements, shall  have an associated  DME maintenance and testing program as defined in Requirement 6.
