摘要
当前使用的数字化电网中,存在感知终端种类较多,对于传统的能耗自动监测系统来说获取的数据传输实时性不足,导致监测结果出现偏差,为此设计一种基于数字孪生模型的数字化电网能耗自动监测系统。系统主要从硬件和软件两方面进行设计:在硬件设计中,根据不同的应用层次,设计系统的总体架构。主要对硬件中的无线通信网络进行搭建,选择基于LoRa无线通信技术的RTU设备作为通信主体。设计LoRa无线开关电路,实现ZigBee设备之间的无线数据传输和交换;软件设计中,设计能耗数据采集主线程,分析数字孪生模型映射交互关系,基于数字孪生模型与实际运行工况之间的映射关系实现能耗指标实时监测。实验结果表明,与传统系统相比,设计得到的检测结果与实际的能耗情况更加相符。
In the current digital power grid,there are many types of sensing terminals,and the real⁃time data transmission obtained by traditional energy consumption automatic monitoring systems is insufficient,resulting in deviation in monitoring results.Therefore,a digital power grid energy consumption automatic monitoring system based on the digital twin model is designed.The system is mainly designed in two aspects:hardware and software.In the hardware design,the overall architecture of the system is designed based on different application levels.The wireless communication network in the hardware is mainly built,and RTU devices based on LoRa wireless communication technology are selected as the communication main body.LoRa wireless switch circuits are designed to achieve wireless data transmission and exchange between ZigBee devices;In software design,the main thread for energy consumption data collection is designed to analyze the mapping interaction between digital twin models,and real⁃time monitoring of energy consumption indicators is achieved based on the mapping relationship between digital twin models and actual operating conditions.The experimental results show that compared with traditional systems,the designed detection results are more consistent with the actual energy consumption situation.
