摘要：

The power system break down or the load interruption that resulted in a complete disruption of power supply to the entire region of North America is discussed. About 400 transmission lines and 531 generating units at 261 power plant has tripped during this breakdown. The first contingency was the loss of a 1,200-MW nuclear unit in southern Sweden due to problems with a steam valve. Most of the power grid breakdown were initiated by single events such as fault or relay misoperation. The weakening of the transmission system, coupled with high power transfer levels, leads to uncontrolled growing electrochemical oscillations between groups of generators. Reduction of the risk of these type of breakdown should be done by maintaining an adequate level of system reliability and security. Some of the new technologies to minimize the risk include flexible AC transmission systems (FACTS) and HVDC, online dynamic security assessment, real time system monitoring, and control.
