| 摘 要： | 小发电机组通过110kV终端变电站并网,增加了小区域系统保护配置的复杂性;若保护配置不当,当系统发生故障时,并网小发电机组可能减弱系统的自恢复能力,扩大事故范围。结合典型的110kV终端主变压器跳闸事故案例,对含小发电机组并网的110kV终端变电站提出新的保护配置原则及具体的防范措施。

| Abstract: | Small generation sets are integrated into power systems through 110 kV terminal substations,which increases the complexity of relay protection configuration;If relay protection is not configured properly,the generators may weaken the self recovery ability of power systems from system accident,which would extend the accident scope;After analyzing a typical accident on a 110 kV terminal transformer combined with a small generation set,new relay protection configuration principles and particular means were brought forward. |
