What is Contingency Analysis? | Necessity of contingency analysis What is Contingency Analysis? | Necessity of contingency analysis Contingency Analysis(CA)is one of the "security analysis" applications in a power utility control centre. Its purpose is to analyze the power system in order to identify the overloads. Contingency analysis is abnormal condition in electrical network.It put whole system or a  part of the system under stress. It occurs due to sudden opening of a transmission line. Generator  tripping. Sudden change in generation. Sudden change in load value. Contingency analysis provides tools for managing, creating, analyzing, and reporting lists of contingencies and associated violations. CA is used as a study tool for the off-line analysis of contingency events, and as an online tool to show operators what would be the effects of future outages. Security is determined by the ability of the system to withstand equipment failure. Weak elements are those that prese...

What is Substation? It is a system utilized to change and to improve the characteristics of the supply system as per load requirements. What is Substation? And Function Of Substation Between the generating station and consumer, electric power may pass through various substations having different voltage levels.  Substations may be owned and operated by an  electrical utility, or may be owned by a large industrial or commercial customer. Functions of a sub-station An electricity supply undertaking generally aims at the following: Supply of required electrical power to all the consumers continuously at all times. Maximum possible coverage of the supply network over the given geographical area. Maximum security of supply. Shortest possible fault duration. Optimum efficiency of plants and the network. Supply of electrical power within targeted frequency limits. Supply of electrical power within specified voltage limits. Supply of electrical energy to the consumers at the lowest co...
