在做好运行维护的基础上,对突发故障和事故应认真分析、判断和处理,根据本人的经验,归纳起来有以下几点: 
(1)先一次设备,后二次设备.所谓先一次后二次,是因为一次设备从表面上看比较直观,容易发现故障存在的问题. 
(2)先易后难.所谓先易后难,就是对设备比较容易处理的部分先检查. 
(3)先动后静.所谓先动后静就是对设备经常处在运行状态的部分先检查,如断路器、隔离开关、熔丝、接点及机械运动部分等.通过这三种方法处理故障,能够比较方便快捷,有始有终,可以少走弯路. 
现就白盆珠电厂一号机组电气部分分析和处理方法为例,一号机组在非运行状态时,其各电气装置都处在正常停机状态位置.当机组开启后,转速达到一定值时,进行起励建压,调节变阻器,改变其励磁电流,使其电流达到额定值,然后投入同期装置.当同期整步表显示同期点两侧的电压、频率、相位一致时,转入并机操作状态,操作1KK开关合闸.此时,断路器拒动.从这一现象可以看出操作机构合闸系统部分可能存在故障或电气部分故障.根据①先一次后二次;②先易后难;③先动后静的检查方法和步骤.首先,检查一次侧设备,对其操作机构部分进行检查,如连杆传动部分以及动静触头等是否存在脱落或松动卡死等现象.经检查未发现一次设备有不良现象时,进行手动操作,若并网成功,说明电气部分一次设备故障原因可以排除,从而缩小了故障范围.接下来就是对操作系统二次侧电气部分进行检查. 
在检查二次部分时,同样根据先易后难,先动后静的检查方法进行检查.一号机组发电机控制合闸回路系统部分如图1所示.检查时,首先用万用表测量控制回路是否存在电源及RD熔丝是否熔断,然后检查1KK在合闹位置时,①、③接点是否接通.检查TK开关投入时①、③接点和{21}、{23}接点是否接通.检查防跳继电器TBJ{15}、{13}接点是否在闭合位置.断路器DL辅助接点是否在闭合位置.HC直流接触器,线圈阻值是否有明显变化.通过这些经常处在动作的电气部件,测量检查都未发现故障存在.此时,转入检查同期小母线1TBM与2TBM的同期控制回路系统部分.同期系统部分接线图
