At present, the standardisation of electrical equipment communications is on the rise. In particular, manufacturers are releasing equipment for the smart grid endowed with communication protocols such as DNP3, IEC 61850, and MODBUS. However, there are legacy equipment operating in the electricity distribution network that cannot communicate using any of these protocols. Thus, we propose an infrastructure to allow the integration of legacy electrical equipment to smart grids by using wireless sensor networks (WSNs). In this infrastructure, each legacy electrical device is connected to a sensor node, and the sink node runs a middleware that enables the integration of this device into a smart grid based on suitable communication protocols. This middleware performs tasks such as the translation of messages between the power substation control centre (PSCC) and electrical equipment in the smart grid. Moreover, the infrastructure satisfies certain requirements for communication between the electrical equipment and the PSCC, such as enhanced security, short response time, and automatic configuration. The paper’s contributions include a solution that enables electrical companies to integrate their legacy equipment into smart-grid networks relying on any of the above mentioned communication protocols. This integration will reduce the costs related to the modernisation of power substations.
目前,电气设备通信的标准化程度正在提高。特别是,制造商正在推出配备DNP3、IEC 61850和MODBUS等通信协议的智能电网设备。然而,配电网中运行着一些无法使用这些协议进行通信的传统设备。因此,我们提出一种基础设施,通过使用无线传感器网络(WSN),允许将传统电气设备集成到智能电网中。在这个基础设施中,每个传统电气设备都连接到一个传感器节点,汇聚节点运行一个中间件,该中间件基于合适的通信协议将该设备集成到智能电网中。这个中间件执行诸如在变电站控制中心(PSCC)和智能电网中的电气设备之间进行消息转换等任务。此外,该基础设施满足电气设备与PSCC之间通信的某些要求,如增强的安全性、短响应时间和自动配置。本文的贡献包括一种解决方案,使电力公司能够依靠上述任何一种通信协议将其传统设备集成到智能电网网络中。这种集成将降低与变电站现代化相关的成本。
