摘要
为提高智能计量装置用电量计量误差监测精度,设计基于数据采集回传的智能计量装置用电量计量误差监测系统。系统分为硬件设计与软件设计两部分。硬件部分由子站与主站两部分构成。主站子系统即主站误差监测机主要包括主站工作机、外围设备、其他信息设备3部分。子站终端由电量采集模块、CT切换模块及PT切换模块构成,主要功能为实现对一次设备的电量、电能表信息数据的采集。软件主要由通信网络与数据库组成。主站子系统和子站子系统通过通信网络实现数据采集回传时的数据信息交互,并在终端设备本地与计量中心分别设置数据库服务器。仿真实验结果表明,该系统性能指标符合电网电量计量规程要求,可替代人工现场监测设备,误差监测结果精准可靠,应用效果较好。
In order to improve the accuracy of power consumption measurement error monitoring of intelligent metering device,a power consumption measurement error monitoring system of intelligent metering device based on data acquisition and return is designed.The system is divided into hardware design and software design.The hardware part consists of two parts:the sub station and the master station.The main station subsystem is the main station error monitoring machine,which mainly includes the main station working machine,peripheral equipment and other information equipment.The substation terminal is composed of power acquisition module,CT switching module and PT switching module.Its main function is to realize the collection of power and energy meter information data of primary equipment.The software is mainly composed of communication network and database.The main station subsystem and the sub station subsystem realize the data information interaction during the data collection and return through the communication network,and set up the database server in the local terminal equipment and the measurement center respectively.The simulation results show that the system performance indicators meet the requirements of power grid electricity metering regulations,can replace the manual field monitoring equipment,the error monitoring results are accurate and reliable,and the application effect is good.
