Application of synchrophasors for over voltage tripping analysis-a case study in northern regional power system of India

The Phasor Measurement Units (PMUs) have gained huge popularity in Electric Power systems around the world. These units are referred as one of building block of Smart Power Grids at transmission level. This paper presents, some of theapplication of Phasor Measurement Units (PMUs) used in Northern Regional Power System of India for advanced power system monitoring, protection, and control.

This paper shares the experience of analysis of multiple transmission line tripping due to overvoltage in Northern Region and also shares the remedial measures taken to avoid recurrence of such tripping.
