To prevent from severe functional difficulties in the power electrical distribution systems under the conditions of environmental limits, liberalization of the energy market and denationalization of the power supply production, where power systems are increasingly working at their utmost performance limits and frequency in order growth the strength of exploitation, the system?s security and reliability in different characteristics of power system operation need to be monitored and maintained. As the necessities of power system operators (SOs) for wide area monitoring system to observe different states and stability of the power system to detect the power quality events and parameters permanently is definitely a major anxiety in the present days and its important rises with the uses of sophisticated devices whose performance is very sensitive to the quality of power supply. This paper is considered about the design and implementation of a low cost multipurpose platform (MPP) for the distribution system monitoring and analysis, which has the ability of analyzing power quality, logging event, measurement of synchronized phasor and inter-area oscillation all together in one device. As the harmonics is one of the main parameter of power quality, a system has been proposed in this paper for mitigating harmonic in the distribution side. The existing systems for power signal monitoring and analysis till now used only six voltage channels and six current channels. With increased number of input channels and use of some better algorithms for the different modes of operations, the result has been improved. The proposed device can therefore aid the requirements of modern electricity markets, encounter the multiple needs of the power SOs and transform an ordinary electricity utility into a system with smart applications.
