This paper presents the statistical analysis of Grid events in the Western Regional Power System of India. The major findings and recommendations derived out of the analysis provided vital inputs for prioritizing the measures to be taken for improving compliance to technical standards, improving the operation and maintenance practices, planning for equipment upgrades and ultimately in enhancing the...
Synchrophasors are used extensively in Indian Grid to detect and analyze faults occurring in the system. This paper majorly discusses the case studies of power system faults that occurred in the Indian grid and its identification and classification using data obtained from Synchrophasors. The types of faults identified include symmetrical and unsymmetrical faults in power system. Further in case of...
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...
Transmission lines protection is one of the important priority of protection engineer as their tripping will lead instability in the grid which may result in cascade tripping. This will put the grid in stressed condition due to increased angular separation between different nodes. Now a days, Carrier based protection scheme for the transmission line is being adopted for most of the transmission line...
On-line power system analysis enables to make power mode-related decision based on information available at real time. The quality of the studies and efficiency of power system operation are closely associated with the accuracy of the power system models. Accurate and quick decision based on analysis on real time data has been necessary for making operational plan under the deregulation of power system...
Electrical load forecasting in power system is a most basic requirement to facilitate the generation scheduling and is an important task for ensuring reliability and economic operation. All around the globe a large number of load forecasting procedures / tools are being used and most of these basically use the statistical data to project the demand on daily/ weekly/ monthly/ yearly basis. However,...
