Blackstart of Combined Cycle Power Plants in Slovak Power System

摘要

Major blackouts of power systems in recent years show the importance of power system stability studies. One of the most discussed stability problems is island operation. Combined cycle power plants are one of the major supplies of Slovak power system nowadays. Their mainly purposes are power generation and household heating. Gas turbines are very well known for their fast response, so it is necessary to discuss their application in blackstart service and restoration process in island operation. One of the most important variables that has to be observed in the island operation is frequency, because power plants could operate safely only in region of 48 to 51.5 Hz. The aim of this paper is to provide a study of blackstart of combined cycle power plants in Slovak Power System and stability of an islanded power system. Simulation results are given. One of the most important results of this paper is to show the behaviour of combined cycle power plants on restoration process in island operation.
