Technical Standard for Complementary Services

Article 3-49 of Title 3-9

It is established that the Coordinator must carry out a PRS Study, at least annually and on the occasion of the SSCC Report, in accordance with the criteria and requirements established in Title 3-9 mentioned above.
‍
In addition, the PRS Study must comply with the provisions of Chapter 7 of the DS125/2019 of the Ministry of Energy, in particular its Article 129, and with the requirements established in Title 7-5 of the NTSyCS, and define the specific requirements of the PRS Services to meet the objective that, after a Total or Partial Shutdown, it is possible to establish the mechanisms that allow, in a safe and organized manner, to restore the electricity supply in all affected electrical islands in the shortest possible time, starting the actions of Rapid Isolation and Autonomous Departure, continuing with the reconstruction of the topological structure of each island until its subsequent connection with the rest of the SEN, through Linking Teams, giving priority supply to Critical Loads.

Some concepts to consider associated with Control Centers (CC) are:
La operational continuity Of the systems EXPIRY,
Lthe redundancy of the power supply (both AC and DC),
Service Recovery Operation Centers (COR)
Autonomous Departure (PA) Requirements,
‍Fast Insulation (AR)

PRS QUANTUM SOLUTION FOR CONTROL CENTERS

This is a summary of the tests that we have executed on the platforms of our clients' Control Centers (CCs), including those designated as Operation Centers for Service Recovery (COLOR), and the operational requirements that they must comply, as established in the regulations of the Service Recovery Plan (PRS) and the Technical Standard for Safety and Quality of Service (NTSycs).

SCADA and SITR Platform Verification Tests

The Coordinator is responsible for ensuring the proper functioning of the Real-Time Information System (SITR) and the platform EXPIRY Of your Control Center (CC), which is essential for information management during a total or partial blackout. The Coordinator may participate in these tests, whose minimum frequency is annual.

Backup and Redundancy Tests

• Power Redundancy: Verify the power redundancy and power backup of all teams involved in sending SITR data (servers, RTU's, etc.). • Energy Autonomy: Power backup teams must ensure a autonomy of 12 hours of operation. • DC Operational Tests: DCs with their own control must perform operational, power supply and communication tests of their Main and Backup Control Center. • Specific SCADA Tests: Tests should be performed on server switching, consistency of the database between sites, and verification of the ability to perform remote control from all servers. • Disaster Recovery Plans (DRP): If the Backup Control Center (CCR) operates unattended, the associated DRPs must be tested for personnel transfers, stating the estimated transfer times. • SCADA availability: It must be validated that the Coordinator complies with an availability of the 99.5% for SCADA, communication links and signals, at least in Last 3 months prior to verification

Performance and Data Time Tests

• Data Avalanche Tests: Simulate a mass recovery generating a data reception equivalent to a 20% of signals or a processing load greater than 90% on servers that send data to the Coordinator's equipment. The objective is to validate the correct submission of SITR variables, complying with the Age of the data And the availability of variables established in the NTSycs. These tests should be Coordinated with the Coordinator upon request via Neomante. • Alarm Avalanche Tests: They consist of the stamping of synchronized binary signals using GPS and sending pulses from technological equipment to simulate state changes (e.g., injecting pulses to an RTU in the field every 5 seconds for 10 minutes). The latency of the links and the verification of the stamping must be recorded at the levels SCADA 2 and 3. • Data Age Tests (Tv​): The lifespan of the data will be verified (Tv) using the field time stamp (T1) and the time stamp of the reception database in the SCADA (T2): Tv=(T2—T1). • Communication Link Tests: Verify the switching to check the correct delivery of information from the field to the Coordinator's data centers

Voice Communication Tests (Hotline)

• The CDC Performs weekly random tests of the main voice communication systems (Hotline) and backup (dedicated landlines, cell phones and satellite phones) of the Coordinated CC. • The COLOR It also performs random tests periodically (at least once a week) of the main voice communication and backup systems with the CCs that you coordinate during the PRS, and report the results to the CDC.

Coordination and Operational Hierarchy (COR vs. CC)

• Delegation of Functions: The Service Recovery Plan (PRS) establishes the delegation of functions for coordinating and supervising maneuvers of the CDC in the Coordinate Control Centers (CC), which are designated as COLOR. • Primary Responsibility: The general coordination of the implementation of the PRS corresponds to CDC. • COR function: Los COLOR are responsible for carrying out the actions established in the PRS in their assigned zone or area, and Instruct the execution of the respective ERS (Service Recovery Schemes), PA (Autonomous Departure) and PPRS (Private Service Recovery Plans) to the CC that it coordinates. • Compliance with Instructions: All companies subject to the coordination of CEN, whose CC are in the area assigned to a COR, must Follow the instructions That it imparts to them in accordance with the PRS. • COR monitoring: CORs must Monitor voltages and frequencies in their areas during charging, ensuring that they remain within established ranges, and have direct communication with the CCs in your area for this monitoring.

Communication and Protocol Requirements

• Use of Roads: The main communication route is the system Hotline, and the backup routes, in order of priority, are: dedicated fixed network phones, dedicated cell phones and satellite phones. • Call Prioritization: CCs must prioritize calls and information requests of the CDC and respective CORs to allow for timely and expedited communication. Deban avoid consulting if they don't have relevant information to submit. • Blog and Registration: In the face of a blackout, all CC and COR must generate a specific blog to record the facts and instructions of the PRS, including the specific date and time of the event and the communication. This log must be submitted to the Coordinator at the latest 48 hours after the recovery process is complete. • Communication Protocol: All communication must be precise and clear; the recipient of the instruction must Repeat verbally the instruction (or paraphrase) and confirm your understanding or feasibility of executing the issuer. • Risk Report: Any limitations or situations you place in Risk of the correct execution of the PRS (such as communication problems, unavailability of visibility, or delays in ERS/PPRS/PA) must be immediately reported to the CDC on the part of the COR and/or CC
