1)Introduction
Security of a power system is affected by three factors:
Characteristics of the physical system:
the integrated generation, transmission and distribution system
protection and control systems
Business structures of owning and operating entities
The regulatory framework
2)What is a blackout?
A blackout refers to the total loss of power to an area and is the most severe form of power outage that can occur in a power system.
Blackouts which results in power stations tripping are particularly difficult to recover quickly.
Outages may last from a few minutes to a few weeks depending on
the nature of the blackout and
the configuration of the electrical network
Largest power outage in history
Occurred as two separate events on 30 and 31 July 2012
Affected over 620 million people, half of India's population
Spread across 22 states in Northern, Eastern, and Northeast India.
5)Preventing blackouts
Long Term plans:
Adequate transmission access to load centers
Sufficient generation
Dynamic simulation
Distributed generation
Short Term plans:
Implementation of special protection
schemes
Proper use of FACT devices
