DESIGN AND DEVELOPMENT OF SUBSTATION MONITORING SYSTEM FOR INDUSTRIAL APPLICATIONS

Abstract

Reliable and Quality Power has become one of the most important issues being faced by the Indian Industries, so there is a pressing need for an effective and cheap indigenous power Quality Analyzer. Power and harmonic Analysis relates to the measurement of power line parameters like total harmonic distortion, rms values of voltages and currents, real power and apparent power and the power factor. To realize this, an instrument has been conceived and developed for demonstrating the energy conservation through energy monitoring during the seminars and presentations of Department of Science and Technology, New Delhi as a part of the Instrument Development Program. The instrument consists of an energy node, RS-232 to RS-485 converter and a personal computer. A DSP based microprocessor system is used to realize the above mentioned parameters. The ADSP-2105 is used for this purpose. The system comprises of Signal conditioners, a 16 bit serial A/D converter, the digital signal proc...
