SVA puts Stalybridge substation protection and automation systems to the test
The System Verification Area (SVA) at ABB’s Stone engineering facility is currently packed with 60 panels of substation protection and automation equipment as it undertakes out what is probably the largest automated FAT (Factory Acceptance Test) of its type ever carried out in the UK. The equipment, all based on National Grid’s standardised NICAP (National scheme for Integrated Control And Protection) philosophy, is destined to play a key role at the new indoor 275kV GIS (gas insulated switchgear) substation that ABB is constructing at Stalybridge, near Manchester.
The Stalybridge NICAP scheme comprises a variety of individual systems that work together to provide complete protection and control of the new 275kV substation and an adjacent 400kV substation, covering feeders, transformers, mesh corners, bus couplers and the overall substation control systems. Over a three-month period, the systems are being given a series of gruelling tests that simulate the behaviour of substation plant such as circuit breakers, disconnectors and earthing switches. The automated FAT, witnessed by National Grid, will provide a complete record of all the tests carried out and, on satisfactory completion, the panels will receive certification for delivery to site.
