一种配电终端残压模块方案的设计与实现

Design and implementation of a residual voltage module scheme for electricity distribution terminals

当前就地型馈线自动化技术引入了残压闭锁合闸的逻辑,以便能快速隔离故障。为实现这一目的,在馈线自动化终端上加入残压模块以实现残压闭锁功能。基于某公司配电终端产品完成了一种基于软硬件结合的残压模块的设计方案,实现电压电流时间型馈线自动化的保护逻辑,并经过测试符合国家电网有限公司发布的技术标准。

Residual voltage lock-up closing logic is introduced into current in-situ feeder automation technology, which can quickly isolate faults. A residual voltage module is added to the feeder automation terminal to implement the residual voltage lock-up function. Based on electricity distribution terminal products of a company, a residual voltage module scheme which combines software and hardware is completed. Itrealizes the protection logic of voltage-current-time feeder automation and meets the technical standards issued by State Grid Company Limited according to tests.
