Upskilling Operator GI : SOP kondisi hilang tegangan

Summary

This video guide provides essential instructions for operators dealing with voltage loss at the 150 kV substation. It emphasizes the importance of safety, such as using protective gear, and outlines detailed steps for handling total or partial blackouts. Operators must ensure the voltage is checked, PMTs are removed, and all disturbances are documented and reported to the dispatcher. The video stresses the need for precise and quick action to restore substation operations, including voltage calibration from other substations. It concludes by reinforcing the shared responsibility of maintaining electrical reliability through adherence to safety protocols and energy procedures.

Takeaways

• 😀 The loss of voltage at the 150 kV substation is a critical condition caused by partial or total blackout, requiring fast and precise recovery actions.
• 😀 Operators must prioritize safety by using protective equipment such as helmets and gloves during a total blackout.
• 😀 It is important to verify that the disturbance includes system or PS traavop disturbance before proceeding with any recovery steps.
• 😀 Voltage metering should show zero café on the conductor and busbar panels, and operators must contact the up2b dispatcher for details about the disturbance.
• 😀 The operator should ensure that the 150 kV PMT Line is removed according to the operating SOP (e.g., red book or up2b instructions).
• 😀 All PMTs (including 20 kV feeder) must be removed and checked, with the time of the incident and any activated indicators or relays recorded.
• 😀 After opening all PMTs, the local remote switch (SLR) should be returned to the supervisory position in preparation for recovery or voltage calibration.
• 😀 Operators must stay ready to receive further instructions from the up2b dispatcher for normalization and restoration.
• 😀 In the case of a partial disturbance, operators should document the incident, record the time, and take photos of the substation's condition.
• 😀 The operational readiness of the installation should be re-checked after voltage restoration, and all actions must be recorded in the operational logbook.
• 😀 Maintaining electrical reliability is a shared responsibility, and all actions should follow established safety procedures to ensure the protection of personnel and the system.

Q & A

What is the primary focus of the video guide?

The primary focus of the video guide is to provide instructions for substation operators on how to handle a loss of voltage at the 150 kV substation, ensuring safety and efficient recovery during emergency conditions.

What does the loss of voltage at the 150 kV substation mean?

The loss of voltage at the 150 kV substation refers to a condition where all voltage on the 150-kilo side is lost, typically due to partial or total blackout conditions.

Why is fast and precise handling critical during a loss of voltage at the substation?

Fast and precise handling is crucial to ensure a quick recovery of the substation and minimize potential damage or prolonged disruptions, with recovery procedures varying based on system conditions and safety protocols.

What is the first step for the operator when handling a voltage loss incident?

The first step is for the operator to protect themselves from potential injury by wearing protective equipment, such as helmets and gloves, in accordance with the Standard Operating Procedures (SOP) for substation restoration during a total blackout.

How should the operator verify the status of the substation after a voltage loss?

The operator must ensure that the voltage metering on the conductor and busbar panels, or the SAS computer, shows zero voltage and should also ask the up2b dispatcher for additional information about the disturbance.

What is the role of the PMT (Protection and Monitoring Terminal) during the incident?

The operator must ensure that the 150 kV PMT line is removed following the operating SOP (e.g., red book or up2b instructions) and continue by removing all PMTs, which are then opened remotely at the substation without the up2b dispatcher’s command.

What actions must be taken if a partial disturbance occurs at the substation?

In the event of a partial disturbance, the operator should document the disturbance by taking photos, record the incident’s time, check all working relays and indicators, and reset the PMT to ensure it is in the open state. The operator should then report the current conditions to the up2b dispatcher.

What should the operator do after restoring voltage to the substation?

After the voltage is restored, the operator must re-check the operational readiness of the substation, record all actions in the operational logbook, and report the latest conditions to the up2b and the team.

What is the significance of the operational logbook in the recovery process?

The operational logbook is essential for recording all actions and conditions during the recovery process, ensuring that every step is documented and that the recovery efforts are transparent and traceable.

What is emphasized as the core responsibility of electrical operators in Indonesia?

The core responsibility of electrical operators in Indonesia is to maintain electrical reliability, prioritizing safety and compliance with good energy procedures as a shared responsibility among all operators.
