摘　　要：电力系统频率是电力系统运行参数中最重要的参数之一,频率质量对社会和电力企业的影响非常巨大,在实际发电厂中,要求频率测量装置,应支持多路频率高精度测量输入和多路模拟或数字形式的频率值输出,用于发电机组AGC/发电控制,而且精度极高。本文以MSP430处理器为硬件核心,直接测量与间接测量相结合,设计了数字式工频测量装置。经试验证明,测量精度高,系统运行稳定。Frequency is one of the most important parameters of power system operation parameters.Frequency quality has a huge impact on the society and electric power enterprise.Frequency measuring device should support multiple frequency precision measuring input and multi-channel analog or digital output frequency values. Based on MSP430 processor as the core hardware, combination of direct measurement and indirect measurement, the author designed the digital frequency measurement device.Through the experiment. the measuring precision is high, the system runs stably.
