REMEDIAL ACTIONS TO PREVENT ELECTRICAL POWER SYSTEM VOLTAGE COLLAPSE

In the paper, the voltage collapse phenomenon in the electric power systems (EPS) is considered as instability of certain transmission paths as shown in [1,2,31. Furthermore, a newly proposed method of modular secondary voltage control [7,81. was utilized to localize generators which are able to improve voltage conditions most effectively. In the paper, a combination of both approaches is presented The combined methods offer useful approach to remedial actions selection against the voltage collapse.
