Research And Implementation Of Power Internet Of Things System Based On Substation

As one of the most important power equipment in the power system,the substation plays the role of collecting electric energy,raising and lowering voltage,and distributing electric energy.Whether its operation is safe or not is directly related to the safety and stability of the power grid system.In the long-term working process of the substation,it is easy to be affected by the aging of the equipment,overheating,and the complex and changeable environment,which can easily cause electrical failures and affect the safety and stability of the power system.Substation sites are multifaceted,and traditional manual maintenance tasks such as heavy maintenance tasks,long periods,narrow monitoring ranges,and high monitoring costs will lead to insufficient supervision of substation safety monitoring,which is very detrimental to the stable operation of the power grid system in the past.Therefore,it is very important to strengthen the construction of the power Internet of Things system in the substation.The underlying foundation of the power Internet of Things system of the substation is the data information collected by its perception layer.In order to solve the problems of complex and changeable front-end equipment and environmental conditions,and the unstable and reliable collection of existing technology,the sensory device and the Internet of Things are based on The new micro-power wireless sensor and edge gateway system scheme of the substation,including the overall architecture,sensor acquisition and edge gateway research,STM32-based wireless sensor network system hardware design and implementation,and software design and implementation.The system scheme is analyzed theoretically,and key technologies such as new wireless sensors,edge gateway technology,coordinated operation strategies,and coordinated operation scenarios are studied^[1].And through the operation example of the intelligent auxiliary control system in the demonstration area,the reliable operation and coordination of the system are verified.The collected data information provides important information for the online monitoring of the operation status of the power grid equipment,the investigation of hidden dangers,and the emergency repair of faults.stand by.The main work of this paper is summarized as follows:1)Based on the analysis of the status quo of the power Internet of Things,summarize the problems of the power Internet of Things system in substations,and discuss the design and implementation methods of power Internet of Things based on substations at home and abroad.A substation Io T system integrating new wireless sensors and edge gateways for related research.2)Research the characteristics and detection principles of different types of sensors,and design the technical solutions for communication and networking of micro-power wireless sensor networks.According to the characteristics of the wireless sensor network,the corresponding edge gateway is designed.3)Propose and design the software and hardware system of the wireless sensor network based on STM32.The hardware design mainly includes:MCU core circuit design,power supply circuit design,programming and debugging circuit design,display storage circuit design,sensor acquisition circuit design,wireless communication Circuit design,etc.The software design mainly includes:485 communication design,LoRa communication design,MQTT network communication design,etc.4)Test and analyze the system of this article based on the actual case of the power Internet of Things system based on the substation,including:equipment installation,data communication,application platform and other aspects of demonstration testing.Based on the actual situation of Taizhou Power Grid Company,this paper conducts research and implementation of sensor communication technology,application layer data transmission technology,edge gateway technology and other aspects in the development of the Dongfang Town substation power Internet of Things system project,and finally goes smoothly in the actual production environment Complete system construction.The research in this article can effectively improve the stability and operating efficiency of the power Internet of Things system in the substation,and bring certain theoretical support to the construction of the Taizhou Power Grid in the power Internet of Things system.
