花瓣式配电网运行典型控制及继电保护

Typical Operation Control and Relay Protection of Petal Distribution Network

“花瓣式”配电网系统接线,是以20 kV出线的变电站为中心,同一个变电站不同主变各出1条回路的电源网络,使闭环网络之间形成明显的联络点,2个闭环运行网络系统通过花瓣形式连接,相互之间中间联络,开环网络运行。网络链接一般是由变电站一条环网网络中重要开关站与另外一座变电站一条环网网络中重要开关站形成联络。

"Etal ype"distribution network system wiring is a power network with 20 kV outgoing substation as the center and one circuit from different main transformers in the same substation,so as to form an obvious contact point between the closed-loop networks.The two closed-loop operation network systems are linked in the form of petals,which are connected with each other in the middle,and the open-loop network operates.The network link is generally formed by the important switch station in one ring network of the substation and the important switch station in another ring network of the substation.
