Power System Control Revised Case Study

Interruption of power supply and its impact can have serious repurcussions on the production cycle, facilities, equipment performance and human productivity. Power outage management is a critical area were technology solutions are required to mitigate the impact of power outages. There are a number of measures available to minimize the possibility of occurrence of black outs, or, mitigate its adverse effects on important class of consumers.

Electric power system comprises components and systems like Generators, transformers, transmission lines and distribution networks, each of which is liable to be affected by insulation failure, due to over voltage or over load. They may also fail under normal service conditions owing to aging or poor quality of material or of manufacturing process. The conductors comprising the transmission and distribution network are also exposed to the elements like lightning, rain, wind, snow etc. which can cause short circuit faults or otherwise damage supporting structures. Insulation failure due to any of these causes lead to trip outs and other disturbances which at times be severe enough to culminate in wide spread power outages or black outs.
