摘　　要：结合国内电力发展现状,首次提出了新型联合循环调峰/调相电站设计方案,在透平与发电机之间设置一自动同步(SSS)离合器,使得机组可以在调峰和调相两种不同运行模式下灵活切换。非调峰时段,透平发电机可以在电网中被"共享",作为同步调相机使用。新型电站显著地提升了电网的可靠性及电网对新能源的吸纳能力,也提升了机组的利用率。与传统的电站相比,该种新型电站既可以"高效"地调峰运行,又可以"零排放"地调相运行。研究成果为未来规划建设燃气-蒸汽联合循环电站提出了一个新的发展方向。According to the development status of China power, the design scheme of a new type of combined cycle power plant （CCPP） for peaking/synchronous condensing is firstly presented as follows： a synchro self shifting（SSS） clutch between the turbine and generator is set up to make the unit switch flexibly at both peaking and spinning reserve modes of operation. During the off peaking period, the turbo generator can be ＂shared＂ as a synchronous condenser in the power grid. The new type of power plant can significantly improve the reliability and the capacity of the grid to absorb new energy and increase the utilization of the unit. Compared with the traditional power plant, this new type of power plant can be not only used in the peaking operation with high efficiency, but also used in spinning reserve operation with ＂zero emissions＂. The research result demonstrates a new development trend for building CCPP in the future.
