| 摘 要： | 针对石油钻机复杂的地质环境易形成跳钻或溜钻现象,提出将混合储能应用于石油钻机微电网以改善电能质量。基于蓄电池和超级电容不同的储能特性,为使功率合理分配,提出一种自适应滤波常数的控制策略。该策略根据储能装置的工作状态实时修正输出功率,并设置了过充过放及最大限值保护,使储能单元运行在合理区间。仿真结果表明该策略提高了储能装置的性能,延长了储能装置的运行寿命,且增加了石油钻机微电网系统的稳定性。

| Abstract: | Aiming at the phenomenon that the oil drilling rigs are easy to form the phenomenon of jumping drills or drift drills in the complex geological environment,the hybrid energy storage applied in the micro-grid of oil drilling rig was proposed to improve the power quality.Based on the different energy storage characteristics of the battery and super-capacitor,in order to make the power reasonable distribution,a coordinated control strategy for adaptive filter constants was proposed.The strategy could modify the output power in real time according to the working state of the energy storage device,and set over-charge,over-discharge and maximum limit protection,so that the energy storage unit could operate in a reasonable range.The simulation results show that the strategy can improve the performance of the energy storage device,extend the operating life of the energy storage device,and increase the stability of the oil drilling rig micro-grid system. |
