摘　　要：110 kV变电站是地区电网十分重要的站点,其安全稳定运行与否直接影响地区电网供电的可靠程度.这些年,我国时有变电站全站失压状况发生,原因有多种,包括保护误动、保护拒动、设备老化、运维不当等.因而,在110 kV变电站全站失压故障出现时,对其原因进行探究,处理好故障,做好预防措施,有其必要性所在.基于此,文章以"9.26"110 kV马塘变电站全站失压为例,分析变电站全站失压故障的主要原因,然后提出故障预防措施,给相关工作者以参考.The 110 kV substation is a very important site of the regional power grid.Whether its safe and stable operation will directly affect the reliability of the regional power grid.In recent years,there has been a loss of pressure in the entire substation of our country for many reasons,including protection misoperation,protection refusal to operate,equipment aging,and improper operation and maintenance.Therefore,it is necessary to investigate the cause of the 110 kV substation’s total station voltage loss fault and take preventive measures after handling the fault.Based on this,this paper takes the“9.26”110 kV Matang substation total station voltage loss as an example,analyzes the main causes of its substation total station voltage loss failure,and then proposes fault prevention measures for the reference of relevant workers.
