小电源接入配电网对自动装置的影响及对策

Influence of small power sources connecting to distribution networks on automatic devices and its countermeasures

分析小电源接入配电网对自动装置的影响,提出基于备自投和事故解列装置配合的解决思路;并对各种典型的接线方式给出具体的解决方法,分析验证了在多种事故情况下所提方法的有效性.且基于配电自动化技术,设计了智能化"网络化备自投和事故解列系统".

The influence of small power sources connecting to distribution networks on automatic devices is analyzed in this paper. The solution method with automatic backup power source transfer and accident separation is proposed. Some specific solutions for typical wiring diagrams are presented. The effectiveness of the solutions has been analyzed and verified in a variety of accident cases. Based on distribution automation technologies, the network automatic backup power source transfer and accident separation system is designed.
