作者陈琳（2019）在《游梁式抽油机混合动力节能系统参数优化及最简控制模型建立》一文中研究指出：随着世界科技的发展,人们对石油能源的需求只增不减。目前大多数需要人工举升的油井均依靠有杆式类别的游梁式抽油机进行采油。游梁式抽油机具有结构简单、运行稳定等优点,但它采油所消耗的电能占油田总电能消耗的40%以上。造成耗能严重的原因是波动率较大的负载增加了电动机选型的装机功率,导致电机具有较低的负载率与效率。据统计,抽油机电动机在一个完整工作周期内的平均功率因数仅为0.448,效率不到50%。因此,游梁式抽油机的低负载率与耗能严重问题亟待解决。通过对国内外大量文献进行阅读与分析,目前针对游梁式抽油机的节能手段主要有改进抽油机的结构、采用节能驱动设备与采用节能控制器,其中,由于我国油田大多数采用的均为游梁式抽油机,将抽油机结构进行调整不易于国内大范围的普及,适用性较弱;采用节能驱动设备与节能控制器固然可以起到一定的节能效果,但对负载率的平衡效果有限,未完全发掘节能潜力,且无法有效抑制倒发电现象。基于以上分析,本文设计了基于液压混合动力的游梁式抽油机辅助节能系统,该系统不仅可以对全国大范围的游梁式抽油机进行节能使用推广,而且可以有效回收驴头势能,改善系统负载率及效率,实现大幅节能。本文的研究内容如下:首先分析了游梁式抽油机的基本结构与工作原理,推导了抽油机结构的几何关系并得到驴头悬点的运动规律,通过对悬点所受静载荷与动载荷进行分析与求解,绘制示功图;继而对抽油机传动机构进行受力分析,求解曲柄轴的扭矩变化规律。选取某型号抽油机作为研究对象,于Pro/E中进行结构建模,并导入Adams软件中进行运动学与动力学仿真,得到游梁式抽油机悬点运动规律与曲柄轴扭矩变化规律曲线,为后文的建模与仿真奠定基础。为了保证节能系统具有较强的适用性,对液压节能系统采用并联式混合动力结构。液压混合动力节能系统可以收集驴头下冲程释放的势能,并将其在上冲程时进行释放,缓解了电动机轴的等效负载波动率较大的情况。对液压节能系统的核心元件进行建模;以电机能耗最低为目标函数,根据变量初始值与变化范围,采用模拟退火算法对混合动力节能系统关键元件进行参数匹配,得到参数优化结果。根据所述液压系统节能原理与关键元件的数学模型,在AMESim中进行模型建立;采用Adams与AMESim联合仿真方法实现负载模拟计算。通过分析仿真结果证实液压节能系统的参数匹配与优化效果良好,节能效果显著,有效降低了电机轴负载的等效扭矩与电机的装机功率,大幅提升电机效率,节省了近25%的电能。为了简化控制系统输入参数,提高系统可靠性及降低工程信号采集成本,建立最简控制模型。基于电机能量流的数学模型,采用遗传算法对模型参数进行优化辨识,并通过Simulink进行理论模型搭建,结合实验数据对比验证最简控制模型可行性。最简控制模型可以把MISO系统简化为SISO系统,提高控制器响应速度,降低系统故障发生率,具有极大工程实践意义。
