Fundamentals of Reactive Power and Voltage Regulation in Power Systems

COURSE NO: E03-011
Fundamentals of Reactive Power and Voltage Regulation in Power Systems
Course Highlights

This online engineering PDH course presents an overview of modern practices in raising efficiency of power systems through application of reactive power and voltage regulation.


It starts with discussion about the structure of power systems from a power plant to the customer, and typical power system voltages in different parts of the system. Then, it explains how power losses and voltage drops in the power system may be reduced through compensation of reactive power either by shunt capacitors for an inductive load or shunt reactors for a capacitive load. Arrangement of a shunt capacitor bank and a sequence of its design is considered as well. Explanations are supported by numerous drawings, photos of actual equipment and the example showing how to design a 230 kV shunt capacitor bank. Finally, it discusses reasons for voltage regulation in power systems and means to perform.  Explanations are supported by photos and example showing how transformer winding taps may be selected.


This 3 PDH online course is applicable to power industry engineers and designers as well as colleges and universities faculty involved with either practical application of reactive power and voltage regulation or teaching its concepts.

Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Understanding why reactive power needs to be regulated
