Implementation of low cost non-DFT based Phasor Measurement Unit for 50 Hz power system

The interconnection of several small & large systems has increased the probability of large blackouts in the power grid. One of the leading reason behind these blackouts is low reporting rate of existing devices and unavailability of synchronized system wide data. Synchrophasor technology provides solution to the problem. Phasor Measurement Unit (PMU) is the most front end device required to implement Synchrophasor Technology. The paper proposes a non-DFT based technique for development of PMU conformed to IEEE standards C37.118.1 and C37.118.2. The proposed technique aims to reduce the processing time & sampling rate which ultimately leads to reduced cost. The hardware of PMU is implemented using Raspberry pi Model B+, ADS1015 and GPS (Global Positioning System) model PA6H on MTK3339 chipset
