Policies for Restoration of a Power System

Policies for effective restoration of a power system are presented. Three plans implement these ideas, covering conditioning, preparedness, and restoration. The problem is tackled with a triple approach, from the viewpoint of installations, personnel, and the restoration plan. Our general restoration philosophy is based on three basic operating principles: decentralized restoration, strength derived from unity, and preparedness, which is achieved through practices and tests. Each of these will be explained briefly. Decay and paralysis of the system mean that it can no longer exist as a whole. Its elements must be rescued, to serve as the starting point from which decentralized restoration can start again. The system´s elements can only be reestablished by dividing, making the network grow gradually with resultant formation of a large system that can bear the full load. Restoration of the system is a heroic undertaking because of the magnitude of the tasks involved and because of the heavy pressure placed on all the elements involved, both human and material. Under these circumstances, it is imperative to have the timely, well-pondered participation of all the resources. Strength of unity is the second principle applied, which attains its true dimension starting from full knowledge of the plan to be followed, which can only be achieved through a thorough, timely, continuous information program, accompanied by detailed training for station and control area operators. Preparedness, being constantly alert, is the third ingredient required.
