Long term effect of power factor correction on the industrial load: A case study

Power quality is one of the major requirements in power system operation and design. A power factor that is close to one is a good indicator for the overall power quality, especially for an electrical power system with high uptake of commercial loads with a large amount of inductance. A poor power factor normally leads to a less efficient electrical system, and may also be less economically efficient for system operators and end consumers. Therefore, power factor improvement plays a crucial role in the efficient system operation and electricity consumption costs reductions. This paper provides a detailed implementation of the technical and economic value of power factor improvement, and it is verified through an analysis of a real-world electrical system and loads. The efficiency of the method to determine the optimum location and size of capacitor installations to achieve desired goals is demonstrated in this experiment.
