摘　　要：介绍了在并列运行变压器经济运行模式下 ,变压器有功损耗的计算和使用寿命分析。提出的双时段控制法在充分考虑变压器及其控制开关运行条件的前提下 ,根据实际运行负荷的变化规律 ,将日负荷曲线分为 2个典型时间段 ,通过调整变压器在 2个时间段内的运行状态 ,最大限度地降低变压器自身的电能损耗 ,延长变压器使用寿命。The active power loss calculation and service life analysis of parallel transformers under economic operation mode are introduced in detail.The proposed TTCM (Two Typical Chronoisotherm Method)divides the daily load curve into two typical chronoisotherms according to the variation rule of real load, which fully considers the operational conditions of transformers and their control switches.By setting the transformer working modes for the two chronoisotherms,the opwer energy loss of transformers is lowered and their service life increased.
