Indian Queens Power Station — Protection & Stability
135 MW gas (diesel) turbines with decoupling clutch, 400 kV connection
The challenge
A 135 MW gas turbine, dual-fuelled to run on diesel and fitted with a decoupling clutch for synchronous condenser operation, is a key asset on the final leg of the transmission system. Aurora has provided ongoing support for upgrades, rework and modifications, and for assessing the site’s suitability for extension through the stability pathfinder programmes.
What Aurora did
We have supported the Indian Queens site over a number of years across a wide range of studies. The work has included options for additional synchronous compensators to provide fault contribution and inertia, MV protection coordination, upgrade of the station transformer, reconfiguration of the overall differential protection, system fault level checks and generator circuit breaker (GCB) performance assessment.
