Application evaluation based on feeders'main/standby power supply relationships and end-user analysis of abnormal operation patterns

为准确评估馈线组供电终端内的用户异常运行行为,从而对配电网环境进行合理的保护,针对基于馈线组主备供电关系及终端用户分析的异常运行方式评估应用展开研究。建立完善的配电系统供电架构,通过供电线连接的方式,计算主要设备元件的实际供电量水平,完成馈线组的主备供电关系分析。在此基础上,确定终端节点的供电能力与可装容量,再联合必要的异常负荷系数,实现对终端用户的异常运行方式评估。对比实验结果表明,与路径描述型评估手段相比,异常运行评估方法支持下,终端主机对于馈线组供电用户异常运行行为的评估准确性达到94%,可在维护常规供电关系的同时,实现对配电网环境的合理保护。

In order to accurately evaluate the abnormal operation behavior of users in the power supply terminals of feeder groups,so as to reasonably protect the distribution network environment,the application of abnormal operation mode evaluation based on the main-standby power supply relationship of feeder groups and the analysis of end users is studied.Establish a perfect power supply structure of the distribution system,calculate the actual power supply level of the main equipment components through the way of power supply line connection,and complete the analysis of the main and standby power supply relationship of the feeder group.On this basis,the power supply capacity and loadable capacity of the terminal node are determined,and then the necessary abnormal load coefficient is combined to realize the evaluation of the abnormal operation mode of the end user.The comparative experimental results show that,compared with the path description assessment method,the evaluation accuracy of the terminal host for the abnormal operation behavior of the power supply users in the feeder group can reach 94%with the support of the abnormal operation assessment method,which can achieve reasonable protection of the distribution network environment while maintaining the conventional power supply relationship.
