【摘要】：在电能表的应用方面,随着其计量准确度和灵敏度的提高,对现有计量技术的准确性也提出了更高的要求,尤其是对电子式电能表的校验方式及校验系统设计就显得尤其重要。目前实际应用领域里所应用的电子式电能表原理都为脉冲输出,脉冲的主要作用是显示其的运行状况。同时,由于电能表作为电能计量的终端,分布范围很广,环境也不尽相同,因此对于电能表不确定度的研究与验证,对于校验系统设计具有十分重要的意义。本文对智能型电子式电能表的校验方式进行分析研究与设计,对电能表的不确定度进行验证,进而设计了一种电子式电能表校验系统,可以提升校验准确度和效率。首先阐述了几种常用校验方式及其缺陷之处,对电子式电能表的计量误差和误差调整进行分析；然后对电子式电能表校验系统软硬件设计做了重点介绍,给出了其数据采集、数据处理和数据融合等模块的硬件设计方法；并给出了FPGA软件设计流程图；最后根据电子式电能表的检定教程,对电能表校验系统进行了功能测试和进行了测量不确定的评定和计算,给出检测报告。通过设计基于SOPC技术的电子式电能表校验系统,加上数据的实时上传,能够最大限度地减少电能表的漏检,假检,而且可以迅速对电能表的工作状态进行综合判断,极大地提升工作效率。
[Abstract]:In the application of watt-hour meter, with the improvement of its measurement accuracy and sensitivity, the accuracy of the existing measurement technology is also put forward higher requirements, especially for the electronic watt-hour meter calibration mode and calibration system design is particularly important. At present, the principle of electronic watt-hour meter used in practical application field is pulse output, and the main function of pulse is to show its running condition. At the same time, as the terminal of electric energy measurement, Watt-hour meter has a wide range of distribution and different environment, so the research and verification of the uncertainty of watt-hour meter is of great significance to the design of calibration system. This paper analyzes and designs the calibration method of intelligent electronic watt-hour meter, verifies the uncertainty of the watt-hour meter, and designs a calibration system of electronic watt-hour meter, which can improve the accuracy and efficiency of calibration. In this paper, several common checking methods and their defects are introduced, and the measurement error and error adjustment of electronic watt-hour meter are analyzed, then the hardware and software design of electronic watt-hour meter calibration system is introduced emphatically, and its data collection is given. The hardware design method of data processing and data fusion module, and the flow chart of FPGA software design are given. Finally, according to the verification course of electronic watt-hour meter, The function test, the evaluation and calculation of uncertainty of measurement are carried out, and the test report is given. By designing the electronic watt-hour meter calibration system based on SOPC technology and the real-time uploading of data, it can minimize the leakage and false inspection of the watt-hour meter, and can quickly and comprehensively judge the working state of the watt-hour meter. Greatly improve working efficiency.
