RELIABLE POWER QUALITY MONITORING AND PROTECTION SYSTEM

Akshay S. Khot

Abstract: In restructured power market, power quality has a direct economic impact on both utilities and industrial customers. Therefore both the utilities and end users of electric power are becoming increasingly concerned about the quality of power. There is no generic solution for all of these problems. Testing of different PQ events is a difficult but very important step. It is also essential to identify the disturbance and clear the problem before it has caused widespread equipment malfunctions and other expensive consequences. So there is an ever increasing need for power quality monitoring systems due to the growing number of sources of disturbances in AC power systems. Therefore automatic detection, identification and classification of disturbances become a very important task. This system has been developed to monitor and detect any disturbance signals in power lines. If disturbance occurs in one of the phase, monitoring system will detect the fault The parameters sent over GPRS network and collected by remote side pc on real time basis where an application is developed using Matlab in which we can get monitoring data in graphical way. The Matlab shows the received data in terms of waveform where we examine power parameters easily
