Q1/ Multiple Choice Questions (MCQ): ( 60 Marks) 1- The secondary control is usually performed in an automatic way, by all the generators that participate to this regulation through: a) Specific (Frequency order) sent by a central controller b) Specific (voltage order) sent by a central controller c) Specific (Set point) sent by a central controller d) Specific (Shut down order) sent by a central controller 2- If the frequency value is higher than the nominal one, so: a) Some generation capacity must be started, or the load has to increase. b) Some generation capacity must be stopped, or the load has to increase. c) Some generation capacity must be stopped, or the load has to decrease. d) Some generation capacity must be started, or the has to decrease. We can define the Restoration condition as: a) The frequency variation between ( 48.5 Hz to 51 Hz ) b) The frequency variation between ( 47.5 Hz to 51.5 Hz ) c) The frequency variation between ( 49.5 Hz to 50.5 Hz ) d) The frequency variation between ( 48.5 Hz to 51.5 Hz ) Which of the three controls in power system is not Automatic: a) Primary Control b) Tertiary and Secondary c) Secondary d) Tertiary
