摘　　要：沿海经济发达地区电力供需矛盾日益突出,发电机组长期顶峰运行现象已相当普遍,对发电机组的安全运行造成威胁。以广东电网火力发电机组为例,详细分析了长期顶峰运行对锅炉、汽轮机及相关系统和设备安全性的影响,在此基础上提出了有利于改善机组安全状况的建议。The contradiction between power supply and power demand in the developed coastal areas in China is increasingly outstanding; therefore the phenomenon of long-term peak operation of thermal power generator sets is very widespread and has caused threats to the safe operation of the generator sets. Taking the thermal power generator sets of Guangdong power grid for instance, the paper not only analyses in detail the influences of long-term peak operation on the safety of boilers,steam turbines and related system and equipment, but also offers suggestions for the improvement of the safety conditions of the generator sets.
