2、cy Scale (kw/ton),高效机房,泵,变频器,冷却塔,主机,机房控制系统,所有设备变频是否意味系统高效？,CPO30控制原理,基于传统的PID控制系统已经无法满足客户对于机房设备日益高涨的节能需求，因为空调系统有如下特点 1、非线性 2、大滞后 3、强耦合 4、时变性特别对于采用全变频系统的机房，其控制参数更多，也更加复杂，为了充分发挥全变频系统的最大节能效果，JCI和OptimumEnergy联合推出了Central Plant Optimization 30机房控制系统,CPO30控制原理,CPO30控制原理,CPO30 LOOP(Optimum LOOP)基于业界最权威的全变
3、频控制专家Hartman的专利控制逻辑Hartman LOOP的基础上而发展的控制逻辑，它主要包括两个部分： CPO30 LOOP Optimum MVM,CPO30控制原理,CPO30 LOOP最核心的控制方法是关联控制（Relational Control），它包括如下三个算法：EMPP(Equal Marginal Performance Principle)-相等边际效能原则 Nature Curve-自然曲线 Demand Based Control-按需控制,CPO30控制原理,EMPP(Equal Marginal Performance Principle)-相等边际效能原则T
4、he EMPP simply states that the energy performance of any system operating with multiple modulating components is optimized when the change in system output (called the marginal system output) per unit energy input is the same for all individual components in the system. 当系统中各个设备的单位能源输入所导致的输出变化一致时，系统
5、效率最高 简述如下： 每个设备的能耗被记录，冷量输出也被记录 调节其中一个设备速度（其它设备速度不变），记录其功率增量和机房边际冷量 把上述被调节设备调回原先速度，再调节第二台设备，输入与第一台设备相等的功率增量，同时记录机房边际冷量 依此重复调节其它设备，每台设备在功率增量但输出冷量不同 同时调节最高效率和最低效率的两台设备，对最高效率仍给出功率增量，但相对上次少一些，而对最低效率设备，给出功率负增量，但绝对值与上次一样，这样机房冷量输出没有变化，但机房输入功率将减少,CPO30控制原理,EMPP(Equal Marginal Performance Principle)-相等边际效能原则,
6、上例说明：当A增加0.4KW和D减少1KW的情况下，冷量输出没有变化，但总能耗减少了0.6KW！,重复步骤1-5，会发现当相等的功率增量加载于每台设备而能够输出相等的系统边际冷量，此时系统效率最高！,CPO30控制原理,Nature Curve-自然曲线,在不同的冷却水出水温度下，机组都存在一个最高效率点，它们的连接线就是机组的自然曲线,CPO30控制原理,Demand Based Control-按需控制,该系统将以如下方式来计算建筑物所需冷量所有阀门的开度；最大，最关键，或最大负荷AHU的阀门位置及最不利压差仅压差当然，最佳方式是第一个！,CPO30控制原理,冷冻泵按需控制冷冻水供水温度不
