一种水电站主变压器电能损耗计算方法

从水电站机组出力持续曲线角度进行变压器的电能损耗计算,精确计算了不同出力下变压器的铜损、铁损的比例及其影响,通过数学建模得出基于发电机出力持续曲线的变压器运行电能损耗方程。以广东惠州东江水利枢纽水电站工程为例,验证了该方法的适用性准确性,为水电站变压器电能损耗计算提供一种新的方法,供相关人员参考。

Power Transformer Economic Capacity Selection in Hydroelectric Station

The capacity selection of power transformer from the point of unit output carves has been analyzed, with accurately considering the proportion of the copper loss and iron loss about transformer under different output. An operating losses equation of transformer is obtained based on generation output duration curve by mathematical modeling, and the capacity of transformer is confirmed. Taking an engineering of a certain power station in Guangdong province as an example, the accuracy of calculation is tested. This provides a new way of transformer power loss calculation and serves as reference for project design.
