POWER QUALITY IMPROVEMENT IN RURAL DISTRIBUTION NETWORK

Abstract

Electric power availability is the prime need for development of rural areas. In rural areas electricity is used for lighting, threshing, house hold purpose and storage of milk, grains and seeds. In India most of the villages are electrified but availability of power quality is not good main reasons behind it are poor planning, no renovation and electricity theft. Power quality determines availability of power to the consumer with good quality of voltage; it contains continuity of supply, no variation in voltage magnitude, no transient voltage and no harmonics problem. This work aims to improve the Power quality for rural distribution which can be done by either conductor replacement or DG placement. With above mentioned methods stability of magnitude of voltage profile can be maintained. For this purpose real time existing rural feeder has been considered and line and load data corresponding to this feeder has been collected. The next step is to replace the old conductor by a new one in order to modify the line data so as to improve the voltage profile. Simultaneously in the same feeder to improve the line voltage a distributed generator has been interconnected with the feeder. With the introduction of new conductor and distributed generator the primitive objective of power quality improvement by stabilizing the voltage profile can be easily - achieved, however technical and economical viability has been carried out to identify which one is cheap, durable, beneficial and reliable among all these methods.
