A break in operation of the electric power system or of its important part is colloquially called the blackout type catastrophic disaster. Such emergency is defined as the electric power system's voltage loss throughout a wide area. In addition, at least 50% of consumers is deprived of power supply, and sometimes the local load islands are maintained (breakdown type 3 or 4). Although the causes and sequence of events differ from case to case, a general common scheme of events leading to the blackout can be indicated. The combination of some random events (breakdowns in grid, power plant tripping, extreme weather conditions) results in exceeding the critical values of the basic technical parameters of system operation ( frequency, voltage), automatic tripping off the power plants from the grid and the voltage loss on the area affected by disturbance. In the paper, the short analysis of recent catastrophic power breakdowns appearing in 2003 is presented.
