Protection of Series Compensated Networks Using Different Techniques: An Overview
摘要
The emerging demand for electricity has made power systems flexible and wider. This increasing demand for electricity can be met by increasing the power transfer capability of transmission lines by inserting a series capacitor. The series capacitor cannot only increase power transfer capability by reducing the line reactance but also aid in system stability, voltage regulation, reactive power balance, and a lower cost of power transmission. The benefits of the insertion of a series capacitor come along with several drawbacks as well. There are several issues faced in the transmission line after adding a series capacitor. The issues are not only limited to the compensated line, but they also impact the performance of adjacent or uncompensated transmission lines. This paper discusses the basic concept behind series compensation along with its advantages and challenges in the protection of the series compensated and its uncompensated adjacent power lines.
