摘要
针对传统城市配电网供电模式柔性切换存在数据传输时延长、丢包率高的缺陷,提出了含分布式新能源的城市配电网供电模式柔性切换方法。将丢包率、数据传输速率、连接构建时间以及时延作为城市配电网性能的探测指标,通过计算电能发射结点与接收结点之间的距离,在电能异常发射结点区域内选取任意两个锚节点,建立供电模式温升异常点的实际距离与测距距离间的修正方程,确定异常点的位置,结合供电模式切换流程,实现了城市配电网供电模式的切换。实验结果表明,所设计方法缩短了数据传输时延,降低数据传输的丢包率。
Aiming at the defects of traditional flexible switching of power supply mode in urban distribution network,such as long data transmission time and high packet loss rate,a flexible switching method of power supply mode in urban distribution network with distributed new energy is proposed.Taking packet loss rate,data transmission rate,connection construction time and time delay as the detection indexes of urban distribution network performance,by calculating the distance between power transmitting node and receiving node,any two anchor nodes are selected in the area of power abnormal transmitting node,and the correction equation between the actual distance and ranging distance of power supply mode temperature rise abnormal point is established to determine the location of the abnormal point combined with the power supply mode switching process,the power supply mode switching of urban distribution network is realized.Experimental results show that the designed method can shorten the data transmission delay and reduce the packet loss rate.
