摘要

针对游梁式抽油机下冲程运行过程中产生倒发电对设备造成损害及电能浪费等问题,通过搭建共直流母线下油井倒发电的工况仿真模型,设计变频调速的互馈节能方法,提出了基于模糊神经网络算法的变频群控互馈节能控制策略。该策略通过实时监控抽油机的运行状态,根据分析和运算确定调频对象和频率增量,使抽油机运行的步调发生改变,最终达到共直流母线电压平稳,倒发电能被其他耗电状态电机利用的效果。实验结果表明,该节能控制策略能有效降低共直流母线电压的波动并利用倒发电能。
        For the damage of reverse power generation to the equipment and electric energy waste problem of down stroke of beam pumping unit during the operation,the simulation model of common DC bus was established,and the crossfeed energy saving method of variable frequency control was designed,a control strategy for energy saving based on control algorithm of fuzzy neural network feedback and frequency conversion was proposed. By reading the real-time monitoring of the operating state for the pumping unit,the frequency modulation object and frequency increment were determined according to the analysis and operation,and the running pace of the pumping unit was changed,finally,a common DC bus voltage stability was achieved,and the reverse power generation was used by other motors. The experimental results show that the energy saving control strategy can reduce the fluctuation of common DC bus voltage and utilize the reverse power generation energy effectively.
