Discussion on Economic Selection of Transformers Based on the DL/T 985-2022 Guideline
摘要
Abstract
This paper discusses the economic selection of transformers based on Guide for determining energy efficiency for distribution transformers,then analyzes the influence of transformer capacity selection on comprehensive energy efficiency cost under the condition of two-part power price,and finally by establishing a calculation model,selects parameters such as transformer capacity,no-load loss,load loss,transformer price,discount rate and electricity prices to conduct a comprehensive analysis on the economic selection of transformers.The research results show that transformer capacity is the main factor affecting comprehensive energy efficiency costs,and that its influence weight is much greater than other factors.The paper also presents a simplified model and design suggestions to optimize the selection of transformer capacity,increase load rate and reduce capacity charge.关键词
