Operation of large-power units in power system,improves its adequacy level,reliability and the energy utilization efficiency. On the other hand,there are also serious impacts on system operation. The influence on transient stability of power system is discussed when large-power units are put into operation. Besides,influence on units' derated output,owed to transfer ability of critical power-flow section,is also analyzed and some advice is presented to improve the transfer ability of critical section. At last,an actual example is given to illustrate system operation and the units' derated output when large-power units are put into operation.
