The medium-voltage series capacitor of power distribution network is mainly used to improve the terminal voltage of long-distance power distribution lines (10kV, 35kV, 66kV and others) and improve the power quality for enterprises and residents.

Medium-voltage series capacitor is mainly used for long-distance medium-voltage power distribution lines. For example, in 35kV and 10kV power distribution network, due to the small power load and far dispersion in remote areas, the length of power distribution line is far beyond the conventional power transmission radius. At this time, the gradual drops of terminal voltage in the power distribution line will result in the abnormal operation of residential power consumption and industrial and mining enterprise load. In this case, the conventional parallel capacitor compensation (column capacitor) or voltage-regulating transformer (1:1 adjustable voltage transformer) cannot fundamentally solve the problem, and the compensation effect will deteriorate sharply with the increase of electrical load at the terminal. Medium-voltage series capacitor can completely solve the above-mentioned problems, shorten the equivalent electrical distance, and effectively improve the terminal voltage of the line.

After the installation of medium-voltage series capacitor, the terminal voltage of the power distribution line is maintained within the qualified range to ensure the normal power utilization at the terminal of the power distribution network in remote area no matter the load at the terminal voltage is light or heavy. The following figure shows the voltage distribution of the 10kV power distribution network (58km) in Qinggouzi, Yanbian, Jilin Province. After the installation of series capacitor, not only the voltage distribution has been greatly improved but also the line loss has also been significantly reduced.
