dc.description.abstractThis research work proposes a novel technique to determine the magnitude of symmetrical components. In the present era, development of microprocessors and their extra efficient controlling plus computing abilities can be utilized to develop a digital protection system. Method of least squares is adopted here to estimate magnitude of symmetrical components under all field conditions. Symmetrical components have been found an effective tool for the analysis of symmetrical and unsymmetrical faults in power system. Moreover, magnitude of symmetrical components are also used as a caution about faults in system. The proposed algorithm, that determines symmetrical components, has less complexity and execution time. The phasor values of voltage is given as an input to the microcomputer that will calculate symmetrical components by applying proposed methodology. Instead of eomputing symmetrieal components again and again for every incoming sample, microprocessor will add impact of every new sample of voltage to the previous estimated values by deploying the proposed technique. This makes the technique unique and simple to implement in microprocessor based digital protection system. These calculations will lead us to the fault occurred in power system. Although the formulation described here is independent of hardware yet it provides a complete analytical base for protection system and is analyzed for different types of fault conditions using simulation tools.
