Optimal power factor correction effects based on energy conservation system

Abstract

This thesis present an application of inverter and power factor correction technique on energy conservation system were presented comprehensively. Some methods were introduced to suppress low order harmonics and improve the power factor correction on the system and their results obtained were discussed. In general, the method of design inverter and filtering systems were identified, and comparative studies were performed based on their ease of applications, clean energy, economic aspects and effectiveness. By designing the necessary techniques and methodology, the overall power factor (PF) and the odd harmonic effects until 7th harmonic distortion were improved in accordance to the expected result. Method of utilizing and testing the variable for inverter and filtering system were performed in this study and was applied to generate clean and recycling energy on the energy conservation system. This thesis present results of the applications of inverter, power factor correction and harmonic control equipment for loads on a different horsepower (hp) of induction motor. This thesis also presented the related techniques of designed full bridge inverter and Hybrid Filtering System. Computation was conducted to characterize the harmonic generated and power factor requirements of the load. The electric utility supplying the new facility required that the induction motor meet the harmonic current limits specified by the IEEE 519 standard. This thesis present the comparisons between the different types of inverter, filtering system such as passive and active filter, conventional power factor correction (PFC) and Hybrid Filtering System were discussed. the comparison is performed between the inverter, filtering system, conventional power factor correction and Hybrid Filtering System to compare the average harmonic from fundamental until 7th harmonic, percentage of total harmonic distortion (%THD), speed of motor, losses and power factor. From the experimental result obtained it was found that total harmonic distortion will be reduced by 7% and the power factor will be increased to 0.97 by using the Hybrid Filtering System.
