Design And Implementation Of Monitoring System Of Unattended Substation

With the expansion of the scale of the power grid,as the most important link between the transmission network and the distribution network,the safety of the substation has become the key of the whole power grid.How to ensure the safety of the substation and reduce the labor cost of the power company has become a major topic at present.Due to the fact that substations are often far away from the city and the distribution among them is very scattered,it is difficult to arrange special workers on duty in shifts.Therefore,it can be considered to use computer communication technology and video technology to remotely collect and remote-control various equipment and environmental parameters inside the substation,in order to realize unattended substation.With the research of power company,I summaried total requirement and collect experience from workers to make the system more useful.At present,some substations have been installed with video monitoring,environmental monitoring and even anti-theft alarm and fire-fighting systems,but most of them are not synchronous.It is difficult to achieve centralized management and comprehensive monitoring of multiple systems,reducing the effectiveness of the system,increasing Add the cost of system maintenance and management.Therefore,we need a set of monitoring system which can chieve the remote monitoring and controlling,which can more effectively prevent accidents and ensure the stable operation of the power system.According to the requirements of a power company for substation remote management,staff reduction and efficiency enhancement,this paper proposes a remote monitoring system for unattended substation.The system first completes the data acquisition of transformer,circuit breaker,temperature and humidity sensors and other equipment in the substation,and then deploys multiple cameras to complete the real-time video acquisition of the substation,uploads the collected data and video to the central monitoring server,and then processes the collected data and video,and can automatically connect with the alarm system based on the data and video At the same time,it also provides substation management,camera management,remote inspection of equipment,regular maintenance,remote control of equipment and other functions,so as to improve the safety and reliability of unattended station operation and maintenance,and gradually realize the visual monitoring and dispatching of power grid,so as to make the power grid regulation and operation more convenient and efficient.
