Abstract :
Maintenance of good quality of power supply is essential for reliability and stability of power system. The effects due to power transformer switching and the transient effects are investigated in this paper. The DWT based techniques are suggested in the past to analyze the transient effects and to respond at a faster rate to improve the quality of power system and its protection. These measures were though efficient in providing better solution but found to be high resource consuming under remote applications. This high resource consumption results in slower response and reduces the reliability in power system. A FPGA based DWT architecture is suggested to improve the efficiency of estimation and response in the power system. The Field Programmable Gate Arrays (FPGA) based DWT architecture is evaluated with theoretical results from MATLAB and were observed to be meeting the accuracy of estimation.
