配电网故障区段判别与隔离改进算法

Fault Section Identification and Isolation Improved Algorithm of Distribution Network

首先在总结目前故障区段判别算法所有节点都参加计算的基础上,针对辐射网络及双电源配电网络,提出了T节点及双电源配电网络的处理策略.同时对双电源配电网络末端故障判断做了改进,把联络开关包含在所有与之相连的线路中.一般地,应用于辐射网络中的算法可以用于"闭环连接,分段供电"双电源及多电源网络.算法实现中以联络开关为分界点,仅选择包含故障信息的线路参与计算,减少了参与计算的节点,提高了计算效率.

At the conclusion of the first section of the current fault identification algorithm for all nodes take part in the calculation are based on the network for radiation and dual power distribution network, put forward a T-node and dual power distribution network of the treatment strategy. At the same time, dual power distribution network to determine the end of failure to do the improvements, the contact switch is included in all the lines connected. In general, the application of radiation network algorithm can be used for ＂closed-loop connections, sub-supply＂ dual power supplies and multi-power supply network. Algorithm in order to achieve contact switch for the cut-off point, only select information includes fault lines involved in the calculation, a reduction of participation in computing node, improve the computational efficiency.
