适应分布式电源接入的钻石型配电网保护应用研究

Application of Protection and Safety Automatic Device of Distributed Power and Diamond Distribution Network

钻石型配电网为分层结构,是具有多侧电源的结构,其运行方式灵活,能够有效提高配电网可靠性,提高变配电设备利用率,同时具有良好的分布式电源接入能力。为充分发挥钻石型配电网的分布式电源接纳能力,有必要进行分布式电源与钻石型配电网的保护及安全自动装置的应用研究,分析了分布式电源接入钻石型配电网的保护及安全自动装置的动作行为,从而为钻石型配电网转型改造提供理论基础和实践依据。

The diamond mode distribution network is a hierarchical structure with multi side power supply. Its operation mode is flexible, which can effectively improve the reliability of distribution network, improve the utilization rate of transformation and distribution equipment, and have good distributed power access capability. In order to give full play to the acceptance capacity of distributed power of the diamond distribution network, it is necessary to study the application of protection and safety automatic device of distributed power and diamond distribution network, and analyze the action behavior of protection and safety automatic device of distributed power connected to diamond distribution network, so as to provide theoretical and practical basis for the transformation and reformation of diamond distribution network.
