Yalong　Bay　ice　storage　district　cooling　system　is　a　very　high　degree　of　automation　system,　the　stategies　of　which　are　detailed　analyzed　in　the　artical　from　three　parts:　refrigerating　system,　chilled　water　distribution　system　and　user　cooling　exchange　system.　For　the　benefit　of　the　environment　and　the　oprerating　efficiency　of　power　grid,　these　control　strategies　are　designed　on　cooling　demand　and　peak　load　shifting.　Now　they　have　been　successfully　applied　to　Yalong　Bay　DCS,　through　the　three　control　hierarchies:　local　control,　centralized　management　and　optimizing　control.　The　artical　has　reference　value　for　design　on　ice　storage　district　cooling　system　control.
