Improvement of Power Factor. Technoeconomical Application in a Case Study at the Industrial Area of Kavala

摘要

Modern power systems are characterized by problems of increased losses and stability trends related to the availability of reactive power. The reactive power is a nonproductive one, necessary for the operation of the interconnected cargo and as well as the operation of distribution networks and transmission of electricity. The importance of reactive power is also shown by the great blackout "Great Northeast" in 2003 due to the loss of it. [1] The degree of reactive power consumption is expressed by the quantity cosΦ, called power factor (PF). The power factor is the ratio of RMS power to the apparent one. The power factor is calculated as follow.
