Method of Detecting of Emergency Cascade Processes in Electric Power Systems

Due to the occurrence of cascade accidents in electric power systems (EPS) actual is the task of creating a tool aimed at their prevention. The influence of EPS heterogeneity on the emergence and development of a cascade process based on experimental data is shown. A technique is proposed for identifying, recognizing the threat of a possible occurrence of emergency cascade processes in heterogeneous EPS. The definition of heterogeneity for electric power systems is given. The occurrence and development of a real accident that occurred in the EPS of the Republic of Bashkortostan is investigated, the possibility of its detection is shown. A technique is proposed for visual presentation of a heterogeneous surface of factors affecting emergency cascade processes in an EPS. The developed method allows to determine the possibility of the emergence and development of an emergency cascade process in the formation and maintenance of the regime, as well as in the design of the development of a EPS to make effective management decisions to increase survivability.
