Comms - Data - 1.0 COM-001 Communications.pdf

Interpersonal Communication: Defined as any medium that allows two or more individuals to interact, consult, or exchange information.
Alternative Interpersonal Communication:
* Serves as a critical substitute for normal day-to-day (primary) communication.
* It does not utilize the same infrastructure or medium as regular operating systems.
Power Line Carrier (PLC):
    * A method of using existing power lines themselves to carry high-frequency communication signals.
    * The process involves superimposing (imposing) a communication signal onto a transmission line.
    * It is most commonly used for communication between protective relays located at both ends of a transmission line.

Real-Time Operation Requirements: Because electricity is instantaneous, it requires real-time operations and extremely rapid decision-making from System Operators, Generator Operators, and Distribution providers.
Reliability Mission: The COM-001 standard (NERC) addresses communication requirements to fulfill the reliability mission. It recognizes that the Bulk Electric System (BES) depends critically on communication for effective operation.
Standard Coverage: Focuses on communication capabilities between:
* Control Centers within the same functional entity.
* Control Centers and field personnel.

Message Types & Audible Methods: Different messages require specific methods of audible communication to be effective:
    * Face-to-face
    * Party line
    * Point-to-point
    * Public address (PA) announcements
The Three Core Components: Every communication process, whether verbal or written, comprises:
    1. Sending the message.
    2. The message itself.
    3. Receiving the message.
Primary Definition: Communication is the process of sending and receiving information on a specific topic with the ultimate goal of reaching mutual understanding.
Mandated Entities for Primary Interpersonal Communication:
    * Reliability Coordinator (RC)
    * Transmission Operator (TOP)
    * Balancing Authority (BA)
    * Distribution Provider (DP)
    * Generator Operator (GOP)
Required Reach: These entities must have reliable communications with each other and with adjacent RCs, TOPs, and BAs as applicable.

Primary Capability: Must have Interpersonal Communication with adjacent RCs in the same Interconnection, and with TOPs and BAs within its own RC Area.
Alternative Capability: Must have Alternative Interpersonal Communication (backup) for all the same entities listed above.

Primary Capability: Must have Interpersonal Communication with its RC, local BAs, DPs, GOPs, and both Synchronous and Asynchronous adjacent TOPs.
Alternative Capability: Must have Alternative Interpersonal Communication with its RC, local BAs, and adjacent TOPs.
Exceptions: TOPs are NOT required to have alternative (backup) communication with DPs or GOPs.

Primary Capability: Must have Interpersonal Communication with its RC, local TOPs, DPs, GOPs, and adjacent BAs.
Alternative Capability: Must have Alternative Interpersonal Communication with its RC, local TOPs, and adjacent BAs.
Exceptions: BAs are NOT required to have alternative (backup) communication with DPs or GOPs.

Primary Capability: Must have Interpersonal Communication with their respective BA and TOP.
Exemptions: There is no regulatory requirement for DPs or GOPs to maintain Alternative Interpersonal Communication capabilities with their BA or TOP.

Verbal Communication Methods:
    * Land-based telephones: The most common method for control center-to-control center interaction.
    * Voice Over Internet Protocol (VOIP).
    * Cellular phones: Primarily for communication with field personnel or as a backup.
    * Satellite phones: Used for field personnel and as a major alternative/backup to landlines.
    * Radios.
Non-Verbal Communication Methods:
    * Email
    * Messaging systems
    * Fax machines
Regional and NERC Systems: Includes systems established by Reliability Coordinators, Regional Reliability Organizations, or NERC itself for all Interconnections.
Importance of Redundancy: Because geographical separation requires electronic means and infrastructure is vulnerable to interruption, redundancy is mandatory.
Redundancy Techniques:
* Looping a microwave system.
* Providing redundant paths using different equipment types (e.g., using microwave for one relay set and Power Line Carrier for the second set).

Management Duties: RC, TOP, and BA must Manage, Alarm, Test, and Actively Monitor vital communication facilities.
Automatic Alarms: Systems must provide automatic alarms to alert operators to failures so corrective actions can be taken immediately.
Failure Notification Rule: If Interpersonal Communication with a required entity fails and lasts more than $30\,\text{minutes}$ , the RC, TOP, or BA must notify affected entities within $60\,\text{minutes}$ of the initial detection.
Alternative System Testing:
* RCs, TOPs, and BAs must test Alternative Interpersonal Communication capabilities at least once each calendar month.
* Repair Timeframe: If a test fails, the entity must initiate repair or designate a replacement within $2\,\text{hours}$ .
Training: Operators must regularly practice with alternative systems (like satellite phones) to account for natural signal delays and ensure emergency readiness.
Telecommunication Coordination: Entities must coordinate to ensure facilities are compatible, investigate problems, recommend solutions, and cooperate on implementation.

Scope: RC, TOP, GOP, BA, and DP must have internal Interpersonal Communication capabilities to monitor real-time conditions.
Internal Coverage: This includes communication between control centers within the same functional entity and between a control center and field personnel.
Medium Flexibility: Internal communications can use any viable medium (Land line, Cellular, VOIP, Satellite, Radio, or Electronic messaging).

R1 & R2 (RC): Must have primary and alternative comms with all TOPs/BAs in area and adjacent RCs.
R3 & R4 (TOP): Must have primary comms with RC, BAs, DPs, GOPs, and adjacent TOPs. Must have alternative comms with RC, BAs, and adjacent TOPs.
R5 & R6 (BA): Must have primary comms with RC, TOPs, DPs, GOPs, and adjacent BAs. Must have alternative comms with RC, TOPs, and adjacent BAs.
R7 & R8 (DP & GOP): Must have primary Interpersonal Communication with their BA and TOP.
R9: Monthly testing of alternative comms; $2\,\text{hour}$ repair/replacement mandate upon failure.
R10: Failure lasting $30\,\text{minutes}$ requires notification of affected entities within $60\,\text{minutes}$ .
R11: If a DP or GOP detects a failure, they must consult affected entities to agree on a restoration plan.
R12 & R13: Mandatory internal communication capabilities for all five entities (RC, TOP, GOP, BA, DP) for control center and field personnel coordination.
