【摘要】 综合考虑配电变压器的经济性与节能性建立年费用计算数学模型,通过将体现负荷曲线形状的年最大负荷利用小时数划分为不同范围,并在各个区划范围内,以典型年最大负荷利用小时数进行损耗计算和模型求解,得到每种变压器容量适用的最大负荷有功功率的范围。从而为依据最大负荷功率和最大负荷利用小时数,合理选择配电变压器提供了方法。更多还原

【Abstract】 Considering the economy and energy saving of the distribution transformer to establish the yearly cost mathematical model, through dividing the yearly largest load used hours that reflected the shapes of load curves into different areas, and getting the typical yearly largest load used hours in the different areas to calculate the transfer’s power loss and solve the mathematical model, it can receive the various load ranges at all of the transformer capacities. The result shows it is a good method to elect the distribution transformer capacity reasonably based on the largest load power and the yearly largest load used hours.更多还原
