This paper forms part of an ongoing system development of the Ghanaian power network. Preliminary studies have shown that the northern sector is venerable to voltage instability which has led to the proposed installation of STATCOM at Tamale. It is therefore necessary to assess the performance of the device when put in operation. Comparison had therefore been made between the use of STATCOM and Fixed Compensator. Line and generator contingencies as well as small signal disturbances analysis had been carried out. Voltage stability is improved with the installation of STATCOM as well as reduction in voltage oscillation during transient. Loadability limit of the system is also increased. Further evaluation targeted at the inter-tie with Burkina Faso has been proposed.

W artykule opisano prace nad rozwojem sieci elektroenergetycznej Ghany. Badania wstępne wykazały, że północny sektor sieci jest wpływa na niestabilność napięcia. Jako rozwiązanie zaproponowano instalacje kompensatora STATCOM. Dokonano jego porównania z klasycznymi filtrami biernymi, zarówno pod kątem potencjalnych awarii w sieci, jak i niewielkich zakłóceń. Proponowane rozwiązanie zwiększa stabilność napięcia oraz możliwości obciążeniowe.
