摘要
500kV同杆双回线在电力系统中具有举足轻重的作用,该项目通过综合两回线信息,将非严重永久故障判据、辅助判据以及按相顺序重合原则完美地结合起来,实现了同杆双回线的自适应重合闸功能,从而最大限度地提高了电力系统的稳定性。目前该项目成套保护装置已通过鉴定,并已推广应用。文章着重介绍了该项目的自适应重合闸的原理及保护配置,并对带并联电抗器的电压判据作了改进。
The 500 kV double circuit lines on the same tower possess the importunt role in power system. Through the comprehension of information on double circuit lines, criterion for unserious permanent fault, auxiliary criterion and principle for reclosing according to phase order are combined perfectly, which realize the function of adaptive reclosing on double circuit lines on the same tower, and raise the power system stability in the maximum limit. Now, this complete protection device has been appraised and popularized. The prhaciples and protection disposition of adaptive reclosing are introduced emphatically, and the voltage criterion with shunt reactor has been made improvernent.
