       广州地铁三号线集中冷站系统构成及特点
        广州地铁三号线集中冷站采用了施耐德高端PL C QUANTUM 控制器系列,对集中冷站和车站进行控制,各车站与集中冷站之间采用多模光纤以太网通讯方式,通讯协议为MODBUS TCP .大大保证了通讯速率和通讯信息量的要求,同时也保证了通讯距离和系统的安全可靠性。送排风及空调系统采用变频器调节风量,水系统二次泵也均采用变频器调节。变频器与通过Modbus通讯接口接入就地远程I/O箱的远程通讯模块上,大大减少了通讯线的距离,避免了干扰。
        ● 集中冷站系统构成
        ○ 集中冷站供冷系统由集中冷站,传输管道和末端设备构成
        ○ 其中供冷系统图如图1-1,冷站系统图如图1-2
      集中冷站系统特点
        与分站供冷方式相比,集中冷站供冷系统需要为多个车站供冷,在供冷范围和数量上都要大得多,有以下几个主要特点:
        ● 冷冻水传输距离长。一般地铁站距在1000米左右,本系统为6个车站供冷,冷冻水传输距离将达 2000~3000米。长距离传输,管路的阻力大为增加,并且系统的热惰性加大,增大了系统的调节难度
        ● 末端设备数量多,供冷管路形成网络。由于各站的负荷情况不同,系统调节时易导致出现相互影响,需考虑整个网络的整体水力平衡
        ● 集中冷站供冷系统的制冷部分,通常采用多机组,二级泵的形式。这种形式适应了长距离管路输送阻力较大的情况,能够减小末端系统对冷机的影响。但是增加了泵的数量和管路复杂性,使调节控制的难度加大
        调节控制方法与策略
        调节控制手段
        ● 广州地铁三号线集中供冷系统中,PLC采用的调节控制手段有:
        ○ 风机变频变风量(末端设备)
        ○ 水泵变频变水量
       ○ 水阀调水量
        ○ 质调节
        调控手段的选择
        由于管路很长,冷冻水从集中冷站到末端设备需要运行数十分钟,如果采用质调节,则调节时滞太大。因此在实时控制中,主要采用量调节的方式(包括风量调节和水量调节)。质调节则采用开环方式,根据外温或季节确定冷冻水温,并在一定时间内(比如1天内)保持相对稳定。
        二级泵管路长,阻力大,且流量直接受末端负荷的影响,因此二级泵采用变频调节,可以达到较好的节能效果。同时为了保证通过冷水机组的水量,一级泵采用定速泵,并与冷机对应运行,不进行变频调节。
        从节能的角度考虑,优先考虑节能效果较好的风机变频和水泵变频调节,尽量少使用水阀调水量的方法。
        控制调节的策略
        初调节
        集中冷站供冷的管路复杂,不同支路之间的阻力差距大,因此需要进行认真的系统初调节,以免系统水力失调,导致运行调节无法正常进行。
        ● 初调节目标:
        ○ 验证系统可以达到设计工况
        ○ 实现系统的水力平衡,为运行调节准备条件。
        ● 调节步骤
        经多次调整,使系统内各机组的流量基本相同(如机组型号不同,则各机组的流量比值应基本相同。流量比值=实际流量/设计流量)。且至少1个机组的阀门为全开状态。
        1、调整一级泵系统水力平衡
        2、设计频率整定
