Completed waterless commissioning of the world's largest turbine unit Xiangjiaba right bank power station
China Drying Network News China Three Gorges Corporation recently released news that the first turbine in the world’s largest turbine has completed water-free commissioning at the Xiangjiaba right bank power station and has initially had power generation conditions. The next step is to conduct a water test and it is expected that grid-connected power generation can be achieved by the end of October. According to Tu Yangwen, deputy director of the Xiangjiaba electromechanical installation department of the Three Gorges Group's Electrical and Mechanical Engineering Bureau, the number of the unit that completed the commissioning work was No. 8. The entire installation work began in February 2011 and the rotor lifting was completed in November of the same year. The final assembly was completed in July. After more than one month of waterless debugging, all aspects are in good condition. Tu Yangwen said that the water turbine unit's waterless commissioning is a functional test of each system and equipment after the unit's final assembly is completed. The first is to check whether the various components, equipment and systems of the unit are in place, and then conduct single system commissioning for “oil, gas, water†and turbines, speed control, generators, monitoring, etc., and finally perform coordinated debugging of the systems. In short, the waterless commissioning is to simulate the actual operation of the unit. In addition to filling the water, all the operations of the unit must go through. Among them, the debugging of the monitoring system is the most important task of the entire debugging work, and is the core of the safe and stable operation of the unit and the power grid. As the largest turbine unit in the world, Xiangjiaba hydropower station has the world's largest generator outlet voltage, which is higher than the 20 kilovolts of the Three Gorges power station generating 23 kV. The staff carried out detailed and careful debugging of the monitoring system to ensure safe and stable operation of the unit and the power grid under high voltage. At present, the staff performs closed management on the No. 8 unit that has completed debugging without water. The dehumidifiers are installed in key parts such as the turbine, generators, and monitoring systems. The top of the unit is covered with a dust cover, waiting for the month of October. Water test. If all aspects of the situation are normal, the grid-connected power generation can be realized as scheduled by the end of October. Xiangjiaba Hydropower Station plans to install 8 units, each with a capacity of 800,000 kilowatts. This is the largest turbine unit in the world with the largest capacity in the world, and its production is entirely localized.
