Substation all-in-thing system scheme based on wireless sensor and edge gateway

物联网前端感知技术的性能决定了泛在电力物联网性能,为解决电网前端感知困难、现有技术单一等问题,针对泛在电力物联网感知层端设备及边缘物联代理,提出了基于无线传感器与边缘网关的变电站全物联体系,包括系统的总体架构和应用框架,研究了新型无线传感器、边缘网关技术、协调运行策略以及协调运行场景实例等关键技术设计的无线传感器具有一体化、小型化、通信方式丰富、智能化、易安装扩展等特性,设计的边缘网关能够满足多专业多类型终端统一接入通过前端传感器物获得电网信息,边缘网关是“终端数据自组织,端云业务自协同”的载体和关键环节,通过示范区物联网运行实例,验证了两者可靠运行、有序配合,达到了电力物联网感知层可靠工作的目标。

The performance of front-end sensing technology in the internet of things determines the performance of ubiquitous power internet of things.In order to solve the problems of front-end perception difficulty and single existing technology,etc.Aiming at devices at the perception level of the ubiquitous internet of things(IOT)and edge IOT agents,a substation all-in-thing system scheme based on wireless sensor and edge gateway is proposed,including the overall architecture and application framework of the system,and the key technologies such as new wireless sensor,edge gateway technology,coordinated operation strategy and coordinated operation scenario instance are studied.The designed wireless sensor has the characteristics of integration,miniaturization,abundant communication modes,intellectualization,easy installation and expansion,etc.The designed edge gateway can satisfy the unified access of multiprofessional and multi-type terminals.Obtain information of the power grid by front-end sensor,the edge gateway is the carrier and key link of"self-organization of terminal data and self-cooperation of end-cloud services",through the example of IOT operation in the demonstration area,good and reliable operation,coordination and orderly coordination of the two is verified,and the goal of reliable operation of the perception layer of the power Internet of things is achieved.
