摘　　要：针对国内电能参数检测装置的局限性,本文基于MSP430FE427单片机技术提出了一种电能参数测量装置,该装置以ESP430为核心处理器,配合外围功能模块,经MCU控制,完成对有功功率、电网频率、电压/电流有效值、功率因数等电能参数的准确测量。实验结果表明,该装置的测量精度约为1%,与传统电能参数测量装置相比,实现了测量系统的SOC设计,降低了设计成本,测量精度较高,系统的抗干扰性强,稳定性更好。该产品的低成本高精度特性使其具有很好的市场前景。For inaccuracy and instability of the electric energy measurement devices,in this paper a new type of electric energy measurement device was researched based on MSP430FE427 MCU. ESP430 is the core processor of the system,and by combining with the external function modules and the control of MCU,it figures out the power parameters,such as active power.power frequency, the RMS of voltage or current, and power factor. Compared with the traditional device, the measurement system has high accuracy, strong interference immunity and the stability of the system is improved.
