Design Of Substation Environmental Monitoring System Based On Internet Of Things

Electric power is one of the main clean energy sources in China,and smart substations play an important role in voltage conversion and power distribution of power systems.With the development of industry and agriculture,the proportion of power operating costs in various fields has increased significantly.Therefore,a sound power monitoring system for intelligent substations can not only enhance the reliability of power supply,but also ensure the quality of power supply and continuous power supply.It is of great significance to the national economy.By analyzing the shortcomings of the current intelligent substation environmental monitoring system,the purpose is to improve the reliability and stability of information transmission in the station’s environmental monitoring system,thereby ensuring the reliable operation of the electrical equipment of the intelligent substation.Using the technical means and methods of the Internet of Things to construct a reasonable monitoring network,the system includes two important components,namely the upper computer and the lower computer,the former includes the local monitoring terminal and the remote monitoring;the main role of the latter is to perform control Command and obtain relevant data.A variety of automation devices are based on information response and retransmission mechanisms to improve the reliability of information wireless transmission.Finally,in the laboratory environment,by making a substation auxiliary equipment model and debugging the entire system,the results show that the system can realize the lighting function in the substation,multi-control access control function,and real-time collection of temperature and humidity node information;it can be obtained after many on-site application tests that the intelligent monitoring system has good reliability,can realize online real-time monitoring and control functions,and meets the previously set expected goals.Through systematic and in-depth comparison and analysis of the two types of information transmission,the two forms of information transmission can meet the wireless operation of information interaction under specific working conditions.However,when the number of devices running at the same time increases,because there are not many nodes allowed in the detection platform based on the RF radio frequency communication form,there will be packet loss and error during the information transmission process,but based on ZigBee information transmission The built-in monitoring system can allow many nodes to maintain a high control success rate even in the case of multiple nodes and large amounts of data.
