一种基于PC的高精度功率测量系统

摘要

High accuracy power measurement system features high design threshold and long development cycle. In order to facilitate the realization and shorten the development cycle, a PC-based high accuracy power measurement system is proposed, the design of this system is relatively simple and easier to implement; its measurement accuracy is up to 0. 02%. The design details of hardware and software are comprehensively expounded, the formulas or technical parameters of critical technologies are given, and the power measurement errors after calibration are listed to prove the high accuracy characteristic, the feasibility and the practical value of the system.%高精度功率测量系统具有设计门槛高、开发周期长的特点。为便于实现和缩短开发周期，提出一种基于PC的高精度功率测量系统。系统设计相对简单，容易实现，测量精度达到0.02%。全面论述了系统硬件设计和软件设计方面的技术细节，给出了关键技术点的公式或技术参数，列出了校准后的有功功率测量误差。相关数据表明，该功率测量系统测量精度高，具有可行性与实用价值。
