Smart grid power line safety real-time on-line monitoring cloud platform based on wireless sensor network technology

Abstract

The invention discloses a smart grid power line safety real-time on-line monitoring cloud platform based on a wireless sensor network technology, and the platform comprises the steps: dividing power lines in a power distribution network, detecting the branch starting end voltage and terminal voltage of each power line in the power distribution network, calculating the voltage difference value of each power line in the power distribution network, analyzing whether the voltage of each power line is abnormal or not, counting the number of each power line with abnormal voltage, acquiring the current of each line area on each power line in the power distribution network, extracting the current of each line area on each power line with abnormal voltage, calculating a current difference value of each section of line area on each power line with abnormal voltage, analyzing a line abnormity type of each power line with abnormal voltage, counting line area numbers on each power line with open circuit and short circuit, and carrying out corresponding early warning reminding, so that related personnel take corresponding treatment measures. Therefore, the troubleshooting efficiency of the power distribution network is improved.

Description

technical field [0001] The invention relates to the field of power line safety monitoring, and relates to a smart grid power line safety real-time online monitoring cloud platform based on wireless sensor network technology. Background technique [0002] With the development of smart distribution network technology and the continuous advancement of power system automation construction, how to effectively monitor the abnormality of power lines in the distribution network has become a new demand point and a hot topic for research in the power production department. [0003] At present, the existing power line safety monitoring technology of distribution network only monitors the instantaneous fault state of the power line, which is mainly used for fault reporting, but does not monitor the state of the power line during normal operation, and there is a lag in monitoring information. As a result, it is impossible to deal with the power lines in the distribution network in a time...

Problems solved by technology

[0003] At present, the existing power line safety monitoring technology of distribution network only monitors the instantaneous fault state of the power line, which is mainly used for fault reporting, but does not monitor the state of the power line during normal operation, and there is a lag in monitoring information. As a result, it is impossible to deal with the power lines in the distribution network in a timely and effective manner. At the same time, the existing technology mainly uses the fault isolation method to manually find the fault points of the power lines in the distribution network, resulting in a decrease in the troubleshooting efficiency of the distribution network. , so that the safe power supply guarantee of the distribution network is affected, and the power outage time in the area covered by the distribution network is increased, so that people's electricity demand cannot be met. In order to solve the above problems, a smart grid power line security system based on wireless sensor network technology is now designed. Real-time online monitoring cloud platform
