Haryana.1857 Revolt popularly known as the First war of Independence ,Th saw
significant participation and resistance in Haryana, with key locations like Hisar,
Rohtak, and Ambala witnessing battles and revolts against British rule. Other main
centres were Hisar,Hansi,Sirsa , Rohtak, Jhajjar, Farukhnagar,Lohanagar and Pataudi
and Dujna, Further will get to know more about the Revolt in Haryana.

But there was also a strand of revolutionary movement, even though not a big one,The Revolutionaries questioned the non-violent approach of the congress.They belived that only violent methods would drive the British from the Country. The activities of revolutionary heroism started as by-product of the growth of militant Nationalism. The first phase acquired a more activisit from a fallout of Swadeshi and Boycott Movement.The second phase started as a fallout of Non-Cooperation Movement. Further will get to know About the important role played by Revolutionaries in different Conspiracy Cases.

The measurement data are more prone to tampering from attackers for mala fide intentions. Therefore, security and reliability of distribution have become major concerns. State estimation (SE), being the core function of the energy/distribution management system (EMS/DMS), has become necessary in order to operate the system efficiently and in a controlled manner. Although SE is a well-known task in transmission systems, it is usually not a common task in unbalanced distribution systems due to the difference in design and operation philosophy. This thesis addresses these issues and investigates the distribution system state estimation with unbalanced full three-phase modelling. The formulation, based on weighted least squares estimation, is extended to include the open/closed switches as equality constraints. This research then explores the vulnerabilities of the state estimation problem against attacks associated with leverage measurements. Detecting gross error particularly for leverage measurements have been found to be difficult due to low residuals. The thesis presents and discusses the suitability of externally studentized residuals compared to traditional residual techniques. Additionally, the masking/swamping phenomenon associated with multiple leverages makes the identification of gross error even more difficult. This thesis proposes a robust method of identifying the high leverages and then detecting gross error when the leverage measurements are compromised. All algorithms are validated in different IEEE test systems.
