风电场工程节能评估中电能损耗计算的探讨

Discussion of calculation for loss of power in the wind farm energy-saving assessment process

目前,风电场节能评估中电能损耗的计算方法和组成有很大差别,文中讨论并计算风机自身耗电的选取、线路和变压器的无功损耗的计算、主变的负载率、站用变压器利用小时数和负载率的选择、无功补偿装置的损耗计算等。建立了较完善的电能损耗计算体系,为今后各个风电场工程节能评估工作的顺利进行提供了重要的计算依据。

The calculation method and composition of electric energy loss in wind farm energy saving assessment are very different.This paper discusses the calculation of the power consumption of the wind turbine,the calculation of the reactive power loss of the circuit and the transformer,the load rate of the main transformer,the choice of the number of load and the loss calculation of reactive power compensation device.The calculation system of electric energy loss is established,which provides an important basis for the future work of the wind farm project energy saving assessment.
