全电驱修井机复合动力系统设计优化及协同控制策略
Design optimization and cooperative control strategy on composite power system for all electric drive workover rigs
摘要
Abstract
In order to solve problems of electric workover rig,such as rapid decay of lithium battery life,large temperature rise of battery pack,and low efficiency of the power system,the composite electric energy storage technology was introduced into the workover rig,to perform the study on the design optimization and control strategy of the dynamic system.The design comparison of power system was carried out.Then the design principles were proposed based on the topology structure of the active composite power supply.A multi-objective optimization method based on the volume,quality,cost,working life,bat-tery life,energy loss and other performance indicators was proposed,and the optimal capacity configuration with lithium bat-tery as the main part and supercapacitor as the auxiliary part was obtained.Finally,according to the characteristics of work-over operation,the conventional logic threshold control strategy was designed,and a hybrid power system adaptive fuzzy logic cooperative control strategy based on the principle of giving priority to the use of power grid and super capacitor was further proposed,which makes the power flow more reasonable.The results show that,without increasing the comprehensive cost,the composite electric energy storage scheme demonstrates the characteristics of high power density,high efficiency and long service life of the supercapacitors,which effectively reduces the high current impact,high rate discharge and frequent use of lithium batteries,and extends the service life of the batteries.At the same time,the high-power charging and discharging ca-pacity and energy recovery efficiency of the power system are improved.关键词
