ROLE OF OPERATORS DURING POWER SYSTEM BLACKOUTS

Ivan Petružela

   Electric power system is a vertically integrated system where energy generation, transmission, distribution and consumption are tied together. Those are juridically different subjects whose operation must respect physical and technical conditions of the transmission, parallel cooperation of plants and unstorability of the electric energy. Implementing of the liberalization on the electric energy market created another economical condition, which influence operating of the power systems. Mental models used by operators are very important for operating. If a mental model does not respect all current influences and restrictions, the system is transferred into an area of higher error rate. As example is used higher occurrence of emergency conditions of electric power systems in economically advanced countries.

Keywords: power system, island mode, blackout, operator, mental model
