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.
