摘要：

为保证抽油机在运行过程中的高可靠性,需要对电压、电流等参数进行实时监测。该文基于先进的自适应陷波滤波器理论,以DSP系统为核心,设计一种具有频率自适应功能,能实现电能谐波分析和电能双向计量的多功能抽油机专用电表。仿真和现场测试表明,该电表抗干扰能力强、计量准确度高,可广泛应用于抽油机采油动态监控和实时评价系统。

Abstract: In order to guarantee high reliability in the process of pumping unit running, need to monitor real-time parameters such as voltage and current. Based on the theory of advanced adaptive notch filter and the DSP system as the core, a frequency adaptive multifunction meter is designed, achieving harmonic and bidirectional energy metering. Simulation and practical running show that the meter has high measurement accuracy, strong anti-interference ability, and can be widely used in dynamic monitoring and real-time evaluation system of oil pumping unit.
