地铁环控大系统基于已知负荷模型的前馈控制策略讨论

对采用屏蔽门制式的厦门地铁1号线地下车站通风空调大系统负荷进行监测,通过试点车站客流量负荷、新风负荷、设备负荷变化等的综合分析,对车站通风空调大系统的运行模式、能耗水平、室内环境控制效果进行梳理总结。在与传统运行模式对比后,提出基于已知负荷模型的前馈控制策略,并进行试点研究。研究表明,基于已知负荷的前馈控制策略可以有效克服传统运行模式中存在的响应滞后问题,同时进一步降低环控系统能耗。

Investigation of Feedback Control Strategy Based on Known Air-conditioning Load of Metro Public Area

By monitoring ventilation and air-conditioning system data from Xiamen Metro Line 1 station and through an investigation and comprehensive analysis of railway passenger flow rate, equipment load, and fresh air requirement in the pilot station, we summarized a running model, energy consumption, and indoor air environment of the HVAC system. Thus, a feedforward control strategy based on the known load model is studied in a pilot underground railway station. The research shows that a feed forward control strategy based on known load can address delay-related problems and reduce energy consumption.
