由 于线路事故,电厂暂时停机,等 线路恢复后,再开机并网发供电。这是发电厂常遇到的事。然而,我们水电厂在一次合110kV线路油断路器向6.3kV母线送电时,却把一台发电机组给冲击了。 事故情况:(见附图)一次110kV线路事故,造成101、103油断路器跳闸,导致厂房三台发电机组(其中两台连接于6.3kV段母线)跳闸甩负荷。值班人员迅速将三台发电机组全部停下,处理在待开机状态。此时 6.3kV母线失压,厂房没有电;主变发出线路事故信
As the line accident, the power plant temporarily shut down, and other lines restored, and then boot and grid power supply. This is something that power plants often encounter. However, when a hydroelectric power plant delivered a power of 6.3kV to a 110kV line circuit breaker, it impacted a generator set. Accident situation: (See attached drawing.) A 110kV line accident caused the 101,103 oil circuit breaker to trip, resulting in tripping of three generator sets (two of which are connected to 6.3kV busbar) in the plant. Staff on duty quickly stopped all three generators, processing to be switched on. At this point 6.3kV bus loss of pressure, no electricity plant; main line sent a letter of accident
