Title: Safety Measures for AGC of Three Gorges Right Bank Hydropower Station
Abstract: The safety of AGC is important for hydropower stations,especially for super-large hydropower stations like the Three Gorges Right Bank Hydropower Station.Not only various error-prevention measures,but also the regulation stability of large capacity units must be considered,which are essential for grid security.This paper introduces the special measures for smooth load regulation of the Three Gorges Right Bank Hydropower Station with AGC of H9000 V4.0.The active power compensatory regulation is taken for large capacity units to ensure active smooth power regulation during starting and stopping processes and through the vibration zone,so the possible load fluctuation of the grid is decreased to the largest degree.The proportional allotment of active power is amended considering the efficiency and abrasion of generator units.Various abnormities of water head are considered in the disposal of water head.Some measures are taken in the switching of double-workstations or AGC functions.The process of active power regulation is monitored to prevent departure from the fixed value.These measures are proved effective in practice.
