压气站辅机系统不间断应急电源的设计

摘要
天然气压气站辅机系统对压气机的稳定运行至关重要,辅机系统一旦失去电源势必会破坏压气机的稳定运行,甚至引发重大事故,故为其配备高性能应急电源(Emergency Power Supply,EPS)十分重要。对EPS储能模块的类型和模式进行了分析与对比,设计了适用于压气站辅机系统的超级电容和钛酸锂电池混合储能EPS,重点讨论了EPS系统的电路设计、直流充放电控制策略。以榆林压气站辅机系统调研参数为依据,利用MATLAB对设计电路进行了仿真分析,确定了超级电容与钛酸锂蓄电池的匹配容量,仿真结果表明:此类EPS能够保证压气站辅机系统失电后在规定的时间内正常工作。(图7,参21)
The auxiliary system of natural gas compressor station is critical to the compressor's stable operation. Once the loss of power happens, the stable operation of auxiliary system will be inevitably interrupted, and even serious accidents may be caused. Therefore, it is quite important to equip a high-performance emergency power supply(EPS). In this paper,EPS energy storage modules were analyzed and compared from the aspect of type and mode, and the hybrid energy storage EPS of supercapacitor and lithium titanate battery suitable for the auxiliary system of compressor station was designed.Circuit design and DC charge/discharge control strategy of EPS system were mainly discussed. Finally, the designed circuit was simulated by Matlab software, based on the parameters acquired in the auxiliary system of Yulin compressor station.And accordingly, the matching capacities of supercapacitor and lithium titanate battery were determined. The simulation results show that this kind of EPS can ensure the normal operation of auxiliary system of compressor station within the stipulated time once the loss of power happens.(7 Figures, 21 References)
