In order to study the reasonable water distribution mode of a power plant under the influence of peak load regulation and explore the possibility of"with water"maintenance of cooling tower,the characteristics of the internal and external field and the thermal performance of a cooling tower were calculated by three-dimensional nu-merical simulation method,which includes two units with six pumps distribute water to whole fill,one units with three pumps distribute water to peripheral fill and one units with three pumps distribute water to half fill.The sub-ject that the air may flow through the unwatered fill when distribute water to peripheral fill and half fill was ana-lyzed,and the effect of the water distribution method on the cooling capacity was calculated.The results show that although there is no air flow through the unwatered fill in the peripheral fill distribution and the half fill water distri-bution,the thermal performance of the zonal water distribution is easily affected by the crosswind,which has a negative effect on improving the thermal performance of the cooling tower under the operation condition of peaking and low load.
