一种快速自愈的分布智能馈线自动化系统

A Distributed Intelligent Feeder Automation System with Fast Self-healing Performance

为了快速切除故障并避免越级跳闸,提出一种基于通用面向对象变电站事件(GOOSE)的分布智能馈线自动化系统。建立了配电网的分区模型,描述了分布智能馈线自动化系统的组成。论述了开环运行配电网和闭环运行配电网的故障定位机理、故障自动隔离机制和健全区域自动恢复机制,并分别以开环运行配电网、闭环运行配电网和多开闭所级联的情形为例进行了详细说明,结果表明所建议的方法能够一次将故障隔离和恢复进行到位,显著加快了故障处理速度并有效避免了越级跳闸,提高了供电可靠性。

In order to quickly clear off the fault and avoid over-tripping,a GOOSE based distributed intelligent feeder automation system is put forward. A partitioning model is established for distribution networks. The structure of the feeder automation system proposed is described. The fault allocation principle,the automatic fault isolation process and the automatic restoration process of the open-loop distribution system and closed-loop distribution system are detailed,respectively. An open-loop distribution system,a closed-loop distribution system and a cascade switch station group are used as examples to demonstrate the approach. It is shown that with the proposed methodology,the isolation and restoration can be implemented at one go without any over-tripping to meet the requirements of customers asking for particularly high reliability.
