When analyzing the quality of electrical power delivered to customers many parameters are considered. However the fundamental issue is the presence of voltage and its reliability and continued presence. Power systems all over the world experience big power failures from time to time leading to a total lack of voltage over a large area - called blackouts. This paper presents an automated method for preventing such a voltage collapse. This method calculates reactive power needed to mitigate the grid and points out the weak nodes where reactive power should be injected. This method was successfully applied and tested on the Polish transmission network.
