Power systems are complex structures that energy production, transmission and consumption units. There are various reasons for energy interruptions on these systems. Power outage on the power system can lead to partial or complete loss of the network. Energy interruptions in large regions cause significant economic losses and precautions must be taken in this regard. In this study, Blackout situations in power systems were analyzed. Within the scope of the study, important Blackout situations encountered around the world have been examined. Blackout causes are listed and interpreted in power systems in the light of experienced events. Precautions have been put forward in order to avoid blackout situations. In addition, the effects of blackstart-equipped power plants on the recovery of the network have been examined.

Power systems are complex structures that provide uninterrupted delivery of electrical energy to the consumer and are expressed as the sum of equipment operated in coordination with each other. However, in some cases, a complete or partial system collapse may occur in the power system. While this system blackout can sometimes be fixed immediately, sometimes it takes a long time to fix it. After long interruptions, social life, daily activities and production activities are interrupted; This leads to a huge financial loss. After a system blackout of the entire power system, elaborate power system restoration plans should be implemented immediately. The location and capacity of blackstart power generation units, which play a critical role in the restoration of the power system, are of great importance in deciding the restoration strategy to be applied after the system blackout. In this study, a simulation study was conducted using real data in order to understand the importance of power generation plants with recovery feature in the system restoration after the complete collapse of the power system. In this study, the behavior of power generation units during the application phases of system collapse and system restoration was investigated. Information is given about the points to be considered while preparing power system restoration plans.
