POWER QUALITY ANALYSIS & POWER SYSTEM STUDY IN 11 KV HT SYSTEMS
Main Article Content
Abstract
This paper presents is to identify the causes for series reactor failures & to monitor and protect the 11 KV power system components and equipments from the Harmonics and Transients and other power quality related problems. Power Quality is a major concern of our modern industries and other consumers. Poor quality of supply will affect the performance of customer equipment such as computers, microprocessors adjustable speed drives, power electronic devices, etc. and result in heavy financial losses to customers due to loss of production or breakdown in industries or loss of life in a hospital. The two major power quality disturbances are voltage sag and harmonic distortion. In the event of voltage sag, due to insufficient energy, equipments may malfunction or trip. Harmonics introduced by nonlinear loads can pollute the input supply to the sensitive equipments and cause the connected equipments to malfunction. In this paper, a Power Quality Provider is proposed and modeled by simulation with the help of external agencies meters.
