Object Oriented Mobile Computing Based Numerical Methods For Harmonic Analysis in Electrical Networks

This paper illustrates a novice method of computation of network currents affected by high order harmonics. The data is received from numeric meters installed at electrical substations and consumers situated at remote end .The data processing are done on a smart phone. The main benefit of these methods is saving in time required for visiting electrical   installations and getting appropriate value of harmonically distorted currents. The numeric meter sends data to the web server of Central Monitoring System either through internet or through PLCC/OFC links. The web server is connected to GSM Network through which the data is received by the smart phone. This data is processed by conducting Object Oriented Numerical Methods based source code available in smart phone. For this purpose, the relevant compilers can be installed in the smart phone. The results are compared with numeric meter data installed at substation end and consumer end.  The difference between ideal theoretical load current and actual harmonically distorted load current is found out from which the degree of harmonic distortion can be ascertained.
