Full digital integrated cylindrical valve drive control unit for hydropower station


Digital Hydraulic Cylinder in Xiluodu Power Station

The international advanced level of identification


Xiluodu Hydropower Station completed the world's largest load cylindrical valve(ring gate) closed dynamic test, the digital hydraulic building miracle

Due to the complex working conditions, the cylindrical valve(ring gate) device is prone to malfunction of equipment, which affects the normal operation of the hydraulic power generation system, and is the bottleneck of the production and operation of hydraulic equipment. The technique has long been dependent on a full set of import, ten years ago, domestic enterprises imitation of foreign system, but has still not been fundamentally breakthrough, is still the waterpower generating equipment the technical difficulty of the highest fault is the most frequent bottleneck.

Full digital integrated cylindrical valve drive control unit is the core technology of hydraulic power generation equipment, is to ensure long-term stable and reliable operation of water conservancy equipment, the necessary equipment. The digital hydraulic drive control unit is the core technology of the cylinder valve. AEMETEC digital hydraulic cylinder valve drive control unit, innovation and breakthrough the traditional servo valve control system scheme, not only system structure is greatly simplified, also greatly enhance the accuracy and reliability of the control system, to create the conditions for end users in a long-term, stable and reliable operation of the commercial utilization.

Full digital integrated cylindrical valve drive control unit has been successfully applied in national key project Xiluodu power station (ranked third in the world), Jinping Hydropower Station, Tankeng Hydropower Station and other.


Report on "China water and electricity":“Xiluodu Hydropower Station completed the world's largest load cylindrical valve(ring gate) closed dynamic test




Set the record for the fastest of Xiluodu hydropower station installed domestic large units, digital hydraulic provides a basic guarantee

China Electric Power Construction Group in 3 months time, 4 sets of Xiluodu power station is the largest unit put into power generation -- a domestic large units to install speed record for the fastest. Units on the right bank of Xiluodu hydropower station has 4 sets of 77 million kilowatts of hydroelectric generating units put into operation ahead of schedule generation, installed capacity reached 308 million kilowatts, from the first unit power to report the same day, has been generating 15.78 million degrees. On July 15, power station's first unit, unit 13 power, than planned in advance for 107 days, become China's second largest hydropower station -- the first of electricity creator of Xiluodu hydropower station. July 24th, unit 10 put into operation, 6 days ahead of schedule. August 23rd, unit 11 put into operation, 7 days ahead of schedule. September 22nd, unit 12 put into operation, 8 days ahead of schedule. A domestic super large unit installed the fastest speed.
