廊坊中南部电网失去电源后的运行方式分析

Analysis on Operation Mode When Langfang Middlesouth Power Network Lost Power

合理的运行方式是保证电网安全运行的重要环节。霸州500kV变电站是廊坊中南部电网最重要的电源,2004年最大供电负荷为581MW。受总设备检修、故障停电随时都可能发生,其单台主变(750MVA)运行不满足N-1要求,因此合理的运行方式和详尽的事故预案,能缩短检修、故障停电时间,减少电量损失。

Reasonable operation mode is one of the key factors in ensuring safe operation of the power network. Bazhou 500 kV substation is an important power source in Langfang middle-south power network. The maximum power supply load in 2004 is 581 MW,single main transformer（750 MVA）service could not meet N-1 requirement. Maintenance of main transformer or receiving equipment and power shutdown could happen anytime. Thus reasonable arrangement and detailed fault prevention could shorten the time of maintenance and power failure,and aslo reduce power losses.
