Abstract

There has been a tremendous increase in the use of variety of electrical equipment in industries and various types of electrical appliances in residential and commercial buildings. There is also an increasing trend in the use of distributed renewable energy sources. Many of these modern equipment/appliances and renewable energy supply systems involve the use of complex electronic/power electronic circuits which result in considerably high harmonic pollution affecting power quality and energy losses. This leads to a need for improved energy monitoring, reactive power compensation and harmonic filtering at the terminals of the loads and/or at the power supply entry points for energy conservation and power quality improvement. This thesis deals with contributions to improved energy monitoring, reactive power compensation, harmonic filtering, protection and demand management incorporating IoT/IR4.0 concepts. The concepts and methodology proposed have been tested and verified by simulation and hardware implementation in single phase systems. The proposed concepts can easily be extended to three phase systems in large residential and commercial buildings and in industries. Many of the existing smart meters measure the rms values of voltage and current, average power and power factor only. Some meters also measure total harmonic distortion. The design and development of an improved IoT based smart meter is presented in this thesis. The proposed smart meter enables waveform data logging and detection of unique load signature in addition to measurement of voltage, current, power and power factor magnitudes. It also enables, clustering of electrical equipment for cost effective reactive power compensation, power quality improvement and demand management.
