【摘要】 为解决日益严峻的供电问题,提高电网的供电能力和经济效益,针对目前单一线路上的动态增容监测装置不能考虑电网综合情况从而导致无法进行正确决策的缺陷,设计了一种基于物联网的输电线路动态增容监测系统构架。在该系统中每5个监测装置中设置1个监测主站,监测装置将所监测到的单一线路数据传输至监测主站,监测主站将数据汇总后传输至后台上位机,后台上位机再根据摩尔根公式计算出容量裕量的最小值供工作人员参考,使其作出更为准确的判断。实验装置安装在连云港某110 k V输电线路上,后台上位机设于连云港供电局,所监测到的数据与实际相符,证明了该装置的正确性与有效性。更多还原

【Abstract】 The dynamic capacity increase on-line monitoring device is urgently needed to achieve the purpose of dynamically increasing the transmission capacity of transmission lines to solve the increasingly serious power supply problems and improve the power supply capacity and economic benefits. At present, the single-line dynamic capacity expansion device can not cover the overall grid integrated situation, and to result in incorrect decision. A dynamic transmission capacity monitoring system based on Internet of Things is designed. In the system, a monitoring master station is set in every five monitoring devices, and the monitoring device transmits the monitored single-line data to the monitoring master station, and the monitoring master station collects the data and transmits the data to the back-end computer. Backstage host computer and then according to the Morgan formula to calculate the minimum capacity margin available to the staff reference, so that staff can make more accurate judgments. The experiment device was installed on a 110 kV transmission line in Lianyungang, and backstage host computer is located in Lianyungang Power Supply Bureau. The measured data isr consistent with the actual data, proving the correctness and validity of the device.更多还原
