Identification of low frequency oscillation disturbance with the help of phasor measurement unit

Sharif, H., Haroon, K.M., Paracha, Z.J., Kaosar, M. and Javed, H. (2020) Identification of low frequency oscillation disturbance with the help of phasor measurement unit. Solid State Technology, 63 (1 Supp.).


An integration of various techniques like measurement, communication, integration with computer,
and control techniques forms a new method for protection and reliable operation of power system which is known as smart grid power system. Phasor Measurement Unit (PMU) is the most important and promising technology among all the technologies which are being implemented for building a smart grid power system. Presently ultra-high and high voltage buses used all over the world are all equipped with PMUs. The main contribution of the paper is to present an application of PMU for determining the source of distribution where the frequency of oscillations is less i.e. the disturbance or fault occurring in power system due to which the oscillations might be very low. These low oscillations might happen due to the resonance phenomenon; therefore, it is of utmost importance to determine the location of disturbance. There are various trial and error techniques which have been implemented but this paper proposes a unique method with the help of PMU to provide the exact response of the system. This method requires minimum time for locating the disturbance which has been validated with the help of case study.
