Synchrophasor Based Application Development In Western India

Power System Instabilities are unacceptable to the society. Indeed, recent major blackout in India had vividly demonstrated that power interruptions or blackouts significantly impact the economy and society. In July 2012, disturbances cascaded through the West -North Corridor transmission system, causing widespread blackout and left 600 million customers without electricity. By nature, a power system continually experience two types of disturbances: event disturbance and load variations. Power System operators need to equip with powerful tools to examine power system stability in a timely and accurate manner. For operational purposes, power system stability analysis plays an important role in determining. Devices like Phasor measurement Units are helping System operators in real time dynamic visualization of the grid and monitoring and assessing the dynamic stability, various application have been implemented based on the PMUs and several are under development. This paper gives an insight into the application of PMUs in Western Grid of India.
