Discussion of safe operation mode of power units after tripout accident of 500kV output lines

Abstract

Abstract: Abstract:When the power grid accident occurred, the power plants must be able to execute the instructions from the dispatching department automatically and quickly to avoid enlarging the power grid accident. At November 5, 2012, three of four output lines of Togtoh Power Generation Company Limited tripped, only one line remained in normal operation. Aiming at this accident, the influence of the tripout accident of output line on the power plant, the accident treatment process in the power plant side and the response scheme were expounded. The feasibility of the scheme was demonstrated, and some shortcomings needing to be improved of the scheme were pointed out.
