Certain Energy Conservation Techniques For Reducing Power Transmission Losses In Low Tension Distribution

摘要

Energy conservation is a great challenge for a country since the economic development is closely linked with the electric energy consumption. The aim of this research is to expedite the efficient usage of energy through quantifying transformer losses, feeder losses and utilization losses through a case study. In this research, a systematic procedure is suggested for evaluating the transmission losses in an industry's LT distribution network is suggested and expressed as per cent of total energy. Loading of transformers and pf of feeders at receiving end are calculated with the actual power flow studies. Energy saving through reducing the energy wastage identified from power study by optimization of transformer loading, power factor (pf) improvement with reactive power compensation at load end, strengthening of conductors to provide ales resistive path for the flow of current and efficient loading of utility is suggested. Also a detailed procedure for calculation reactive power requirement, energy saving due to pf improvement and conductor strengthening is suggested based on actual industry running conditions. A textile yarn manufacturing industry has been considered for analysis because of i) the higher intense magnitude of electrical energy used required as both active and reactive in such industries, ii) large variation in load factor of the industry with different load factor motors, iii) wide variation of demand due to sudden stoppage and start of machines depends on the operation and iv) the large number of textile industries in the country. By implementing the reduction techniques as suggested, energy efficiency of the industry is increased.
