Abstract

The proposed project envisages a new adaptive scheme of protection that provides a centralized monitoring mechanism using PMU inputs, to achieve the following objectives for a real-time power system : i) to provide assertive trip signal for genuine faults detected in the protected line. i) to provide a blocking signal for spurious faults / load encroachments in the zones of protection. ii) in the absence of PMU data (due to communication failure / equipment failure), the protection schemes will continue to be in service using local measurements. This will enable to overcome certain drawbacks of the traditional protection system which work with local measurements, thereby helping in considerable improvement of security and reliability of monitoring and protection of the electric system. The essential target of any back-up insurance is to give a second line of assurance to clear any blame on the framework. To achieve this goal, the back-up defensive framework must have the option to fulfill the meet the accompanying useful necessities: (1) It ought to catch the life of all issues which emerge inside its endorsed district of wellbeing. (2) It must find the disappointment of the essential wellbeing to clean any blame as intentional. In clearing the flaw from the machine, it need to play out the ensuing highlights : a) start the stumbling of the base assortment of circuit breakers. B) Operate sufficiently fast (reliable with coordination necessities)
