| Abstract: | For the further development of framework for defending blackouts,we discussed the functions,control modes and system structures of wide area protection of electric power systems,which include wide area equipment protection systems and wide area system protection systems,and reviewed recent developments in the information acquisition,knowledge extraction,and decision making of wide area protection systems.Moreover,from a viewpoint of combining both theory and application,we discussed the feasibility and further development of wide area backup protection.It is pointed out that major breakthroughs should be made in algorithms and knowledge extraction technologies from disturbed trajectories,and numerical simulations should be combined,so that the advantages of phasor measurement units can be fully utilized in wide area protection systems.It is also emphasized that wide area protection systems should be coordinated with preventive control and conventional protection from the viewpoint of risk management. |
