Impact of shunt compensation in improving voltage level of overhead transmission lines

Shunt compensation is widely used in alternative current transmission and distribution networks to produce reactive power support. Located in critical points such as vicinity of load centers, the use of Shunt compensation has beneficial effect on power system performance. The focus of this paper is a case-study in Albanian Power System: the implementation of Shunt Compensation in transmission network. For the most critical part of the network, there are performed simulations in two situations: without reactive compensation and with shunt compensations. The simulations data results to be in compliance with measurements data of the voltage for overhead transmission lines at levels 110kV and 220kV. By this way, the paper presents the impact of shunt compensation in improving voltage level of transmission network
