A algorithm for phasor estimation based on demodulation for Phasor Measurement Unit (PMU) in compliance with the IEEE standard C37.118.1 is presented. The proposed technique can play key role in power transmission as well as distribution networks to measure the peak amplitude and phase angle of sinusoidal signal. The researchers on accurate estimation techniques for phasor measurement have to be carried on to challenge next-generation smart and micro grids. The proposed technique does not use any compensation techniques during the computation of phasor estimation, even in case of sudden power system frequency deviation or dynamic measurements and it gives fast and accurate response. The validation of the proposed technique is presented, thereby using the test conditions adopted by the IEEE Standard C37.118.1. The Total Vector Error (TVE) during phasor estimation for the considered test signals is found to be within limits specified in the standard. The electrical power transmission system and three phase series power compensation network are considered as a test case for simulation studies in order to obtain the performance of the proposed phasor estimation technique so that it may be used in real life conditions. Thus, PMU incorporating proposed technique can be used by the researchers to find the instantaneous phasor estimation of voltage or current signal at greater accuracy in large interconnected power transmission and distribution networks.
