Abstract

In this paper

the basic principle on solving the low voltage issue of 10kV distribution line by the use of series compensation technology is described. Determination of installation position of series compensation device and calculation method of such basic parameters as capacitive reactance

rated voltage and rated current etc of series compensation capacitor are proposed. No any influence on the over current protection setting by the series compensation device with adoption of thyristor is described from the principle. The remarkable result by the use of the technology in solving the low voltage issue and reducing loss and saving energy is verified further through real example and the experience and lesson in the engineering application are summarized.
