摘　　要：根据电力变压器负荷变化引起其有功损耗的改变,研究两台容量相同的变压器经济运行方式,通过技术分析及论证,得出两台变压器在负荷、容量相同下,若其参数不同,则其损耗不同,在负荷不超出30%变压器容量时,用一台变压器运行比两台变压器并列运行经济,能减少有功损耗,使电力系统经常处于经济运行方式,将变压器电能损失降为最低。Because load change can lead to active loss change of electric power transformer, we researched the way of economic operation of two transformers having the same capacity. By the technological analysis and proof, we can conclude that their loss is different if they have the same load and capacity and different parameters. When load is no more than 30% of transformer capacity, using one transformer is more economic than using two transformers in parallel connection. So can reducing active loss and making electric power system run in economic operation and transformers loss is the least.
