| 摘要: |
| 介绍了并列运行双绕组变压器经济运行方式优化的方法。提出了一种变压器经济运行的时段控制法:根据短期负荷预测的数据确定未来1日的日负荷曲线,并将该曲线分段,再结合变压器经济运行理论,设置变压器在各个时段内的动作次数,最终确切地给出变压器经济投切的时机。最大限度地降低了变压器自身的综合功率损耗,同时减少了设备动作次数。实例分析表明该方法具有较好的经济效益。 |

| Abstract: |
| Principle to optimize the economic parallel operation of two-winding transformers is introduced and the time-interval control method is presented.It divides the daily load curve into intervals according to short-term load forecast data.The transformer action times within each interval are set according to transformer economic operation principle,and the optimal switch-on / off time are then determined.Both the complex power loss and action times of transformers are deduced.Example analysis shows that it brings great benefit. |
| Key words: transformer,economic operation,short-term load forecast,time-interval control method |
