ABB LCC ECS - 2 © 2004  Power Management – Introduction (1) What ? Why? The control of electrical switchgear and equipment To optimise electricity generation and usage and to prevent major disturbances & plant outages (blackouts) Where is it required ? In the context of a green-field installation a major extension or modification of a brown-field plant In plants with a substantial electrical load (from 30 MW upwards)In plants with major electricity generation facilitiesIn cases where there is no or a poor grid supply or the need to limit imported power
