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...
System Protection Schemes (SPS) are considered as an effective tool for enhancing the resilience of the power system towards rare contingencies. The validation of SPS is difficult by using conventional SCADA data due to its inherent low scan rate and skewedness. Under such condition, Synchrophasors has been found to be better suited for performance evaluation SPS and review of its design. This paper...
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...
Electricity grid interconnections have played a key role in the history of electric power systems for economic and optimum utilization of resources. Most national and regional power systems that exist today have begun many decades ago as isolated systems. In similar way, Indian grid has also evolved from state grid to regional grid and then their synchronization one after another. On 31st December...
