Definition: Series compensation is the method of improving the system voltage by connecting a capacitor in series with the transmission line. In other words, in series compensation, reactive power is inserted in series with the transmission line for improving the impedance of the system. It improves the power transfer capability of the line.
In a transmission system, the maximum active power transferable over a certain power line is inversely proportional to the series reactance of the line. Thus, by compensating the series reactance to a certain degree, using a series capacitor, an electrically shorter line is realized and higher active power transfer is achieved.
The fixed series capacitors are the most cost-efficient solution. Their simple, proven and robust technology supports transmission system operators by optimizing power transmission and increasing transmission capacity. Siemens Energy is proud to reiterate: All major components are sourced in-house.
