石油钻机起下钻工况中的载荷呈现脉冲波动特性,为了应对短时冲击负荷,有必要引入飞轮储能调峰运行技术,以平抑发动机的功率突增,减少动力热备容量,达到节能减排的目的。提出一种基于飞轮储能的混合动力传动系统,飞轮储能系统储存辅助发电机的小功率电能、下钻工况中的势能回收电能,大功率释放电能供给调峰电机。飞轮储能系统与绞车下钻势能回收系统、辅助发电系统、调峰电机系统组网联合调试,在卫453井示范工程中进行调峰试验、液力耦合器配置试验、能量回收功能试验、调峰电机系统电气总控试验。试验结果表明,飞轮储能动力调峰系统能够快速响应载荷的变化,将柴油机在响应冲击负荷时的功率突增减少40%~58%。柴油机与链条并车箱之间的液力耦合器可以用传动效率更高的齿轮变速器替代,无液力耦合器的混合动力系统油耗可降低10%以上。
In order to cope with short-term impact load, it is necessary to introduce flywheel energy storage peaking operation technology to stabilize engine power surge, reduce power reserve capacity and achieve energy saving The purpose of the row. A hybrid powertrain system based on flywheel energy storage is proposed. The flywheel energy storage system stores the low-power electric energy of the auxiliary generator, the potential energy in the down-drilling condition recovers the electric energy, and the high-power releases the electric energy to supply the peaking motor. Flywheel energy storage system and winch bottoming potential energy recovery system, auxiliary power generation system, peaking motor system networking commissioning in Wei 453 well demonstration project peaking test, hydraulic coupler configuration test, energy recovery function test Peak motor system electrical total control test. The experimental results show that the flywheel energy storage peaking system can respond quickly to the change of load and reduce the sudden increase of diesel engine sudden surge by 40% -58% in response to impact load. Hydrodynamic couplers between the diesel engine and the chain-and-box can be replaced with higher-efficiency gear transmissions, which reduce fuel consumption by more than 10% in a hybrid powertrain without a fluid coupling.
