Power factor improvement Houshmand, Nazanin


This project investigates power factor improving equipment for the following buildings on UBC campus: Life Science, Biology West, Chemistry Physics, Forest Science and Michael Smith. My objective throughout this project was to write a Microsoft Excel program that would be able to calculate the capacitor values needed to improve the power factor, and increase the life span of the transformer due to the addition of the equipment. Additionally, the program enables users to calculate the amount of yearly savings, based on the installation of the capacitors and the savings resulting by the reduction of greenhouse gas emissions, given the real power as well as the power factor. This report will discuss the different aspects of the project, such as the equipment and methodology, and the calculations and results. In the end, I was able to complete my goal of creating a Microsoft Excel file that will calculate all the necessary information for future projects as well as recommending corrective equipment for each building. The Microsoft Excel program can easily be extended to include calculations of value of money and the possible repair cost.
