The aerodynamic behavior of the fans array of the direct air-cooled condenser is different from that of a single fan because of the interaction effect between fans and the influence of wind. In this paper, a scale-down fan array experimental platform with measurement of the airflow and ambient wind speed is established to study the fan array partition schemes and cluster effect. The divisional cluster factors are obtained by experiment and generalized by random forest regression. The dynamic models of the condenser backpressure are introduced by the moving-boundary method. To achieve transient performance, a divisional control strategy for the direct air-cooled condenser is realized by MPC-PID cascade control. The simulation result shows that the fan power consumption is reduced by 14.7% compared to the existing control strategy. Furthermore, the wind speed disturbance is quickly suppressed cascade control.

基于分区调节的直接空冷冷凝器节能运行

由于风扇之间的相互作用和风的影响,直接风冷冷凝器的风扇阵列的空气动力学行为不同于单个风扇的空气动力学行为。本文建立了一个可测量气流和环境风速的按比例缩小的风扇阵列实验平台,以研究风扇阵列分区方案和集群效应。划分的聚类因子通过实验获得,并通过随机森林回归进行推广。凝汽器背压的动态模型由移动边界法引入。为了实现瞬态性能,直接空冷冷凝器的分区控制策略是通过MPC-PID串级控制实现的。仿真结果表明,与现有控制策略相比,风扇功耗降低了14.7%。此外,
