摘要
针对全厂停电事故对火力发电厂的安全生产构成严重威胁,造成直接经济损失的同时,停电事故也危及全厂设备的安全问题,以某发电厂送出线路跳闸而引发的全厂停电事故为例,从机组主保护设置、设备电源、仪用气源等方面进行了改造,改造后增强了机组适应极端运行工况的可靠性。
The power outage of the entire plant poses a serious threat to the safe production of thermal power plants and causes direct economic losses.At the same time,the power outage also endangers the safety of the equipment of the whole plant.Taking the power outage accident of the whole plant caused by the tripping of the transmission line of a power plant as an example,this paper discusses the main protection setting of the unit,equipment power supply,instrument gas source and so on.After the transformation,the reliability of the unit to adapt to extreme operating conditions is enhanced.
