Industrial Visit to PGCIL 400 kV Power Grid Ghanpur Substation
The IEEE PES/PELS/IAS Joint Chapter is organizing an on-site industrial visit to the Power Grid Ghanpur Substation (400 kV)- an Extra High Voltage (EHV) transmission hub operated by Power Grid Corporation of India Ltd. (PGCIL). This substation is a key node supporting bulk power transfer and regional grid stability for the Hyderabad region, with connectivity linked to major generation corridors (including plants such as Nagarjunasagar and Ramagundam).

Expanded Technical Learning Highlights (what you will observe & learn)
Participants will gain practical exposure to how a 400 kV EHV substation supports long-distance transmission and reliable supply to load centers:
Grid Role & Power Transfer
>Why 400 kV is used for bulk transfer (reduced current for the same power, lower losses, improved transfer capability).
>How EHV substations improve reliability through redundancy and contingency planning (typical N-1 philosophy).
Substation Layout & Single Line Understanding
>Interpreting the single-line diagram (SLD): bays, busbar schemes, bus couplers, feeder arrangements.
>Understanding switchyard zoning and safe movement paths.
Primary Equipment Walkthrough (Switchyard Exposure)
>Busbars, insulators, gantries
>Circuit breakers (interruption during faults/operations)
>Isolators/disconnectors and earthing switches
>CTs / PTs / CVTs for metering & protection inputs
>Surge arresters for lightning/switching surge protection
>Wave traps / PLCC (communication over transmission lines)
Power Transformers & Reactive Power Control
>Transformer basics, cooling, and tap changers for voltage regulation
>Voltage support via reactors/capacitor banks (reactive power management)
Protection, Control, and Automation
>Protection concepts: distance protection, differential protection, busbar protection, breaker failure logic
>Basics of interlocking, alarms, event/disturbance recording
Control Room & SCADA Exposure
>Overview of SCADA/RTU, measurements (V, I, MW, MVAr), status indications
>Operational coordination and monitoring philosophy (high-level)
EHV Safety Practices
>Approach distances, PPE discipline, do’s & don’ts in live EHV environments, safety briefings and compliance.
