  turbine output
Also provides stabilization of wind turbine output and is a source of reactive energy.
      
By using a combination of booster and supplemental air compressors for the gasifier, the Gas turbine output will be more consistent.
      
Control and optimization of the wind turbine output is controlled by power regulation electronics, provided by the wind turbine manufacturer.
      
However, when HRSGs cannot meet steam requirements, turbine output is increased to provide steam and electricity for chillers.
      
Most of the turbine output is used as motive power, but some is used to drive a compressor to provide air for the combustion process.

The adjustable-speed pumped-storage generator-motor is excited by two-order three-phase alternating current. The rotor of generator-motor is cylindrical, and the windings of rotor are fabricated on three-phase distributed windings basis. Thc functions of this generator-motor is identicalwith conventional pumped-storage generator-motor. The variable range of imput power can reach ± 80MW as pumping operation with a definite head, and it can stabilize the frequency of electrical sys-tem. The generator can operate...

The adjustable-speed pumped-storage generator-motor is excited by two-order three-phase alternating current. The rotor of generator-motor is cylindrical, and the windings of rotor are fabricated on three-phase distributed windings basis. Thc functions of this generator-motor is identicalwith conventional pumped-storage generator-motor. The variable range of imput power can reach ± 80MW as pumping operation with a definite head, and it can stabilize the frequency of electrical sys-tem. The generator can operate with optimum output speed. The generator can operate with optimum output speed. The range of output variable is wide. The overall efficiency is high with partial load. It can control active power swiftly (about 10ms) even if no apply governor, and have no relation with pump-turbine output. It can improve the stabilization of system, and control over-voltage caused by all troubles. It can operate continually when there are over-voltage, failure of rotation direction chang-ing and system troubles.

可变速抽水蓄能机采用二次三相交流励磁.转子呈圆筒形,其绕组三相分布.可变速抽水蓄能机组具有与常规抽水蓄能机组相同的功能.且在一定水头下抽水运行,负荷可调范围达±8万kW.并能稳定电网频率;发电工况可在最优出力转速下运行,出力变化范围大,部分负荷时综合效率高,不用调速器能高速(数十毫秒)控制有功功率,而与水泵水轮机出力无关,可提高系统稳定性.可抑制各种事故造成的过电压,并能在过电压和换向失败、系统事故时持续运行.

The cavitation and abrasion of hydraulic turbines in the silt laden water were discussed. Some experiences in repairing the parts damaged by cavitation and abrsion and protective measure, such as repairing and modifying runner bucket, seting baffle at head cover, improving the structure of runner band seal were introduced in delail.

水轮机在含沙水流中运行时,常遭到泥沙磨损和磨蚀破坏。本文主要介绍作者近年来在中小型水电站,对水轮机的易磨蚀部件进行修复、修型、改型等抗磨蚀措施方面的实践情况。通过综合治理,使水轮机出力增加,抗磨蚀性能提高。
