| 摘 要： | 研究降低发电厂联络变压器损耗的控制策略.在变压器不停运的状态下,调整发电厂的输出功率,降低联络变压器的有功功率和无功功率的损耗.借鉴电力系统计算快速分解法的思想,将控制策略分成两步来实现,即首先调整发电机节点的有功功率,用来调整联络变压器上的有功潮流,减少联络变压器的有功损耗;其次调整发电机机端电压或者无功功率,用来调...

| Abstract: | The control strategy for loss reduction of power plant’s connecting transformers is researched in this paper.Considering the non-stop operation state of the transformers,adjusting the output power of power plants,active and reactive power losses of the connecting transformers are thereby reduced.Learning and using the idea of rapid decomposition in power system calculation,the control strategy is divided into two steps.Namely,first adjust the generators active power,which can be used to adjust the active power flow of the connecting transformers,thereby reducing the power loss.Second,adjust the generators terminal voltage or reactive power,which can be used to adjust the voltage across the connecting transformers,thereby reducing the reactive power loss.Based on the actual operation data of the Chinese power grids,computer simulation results show the proposed control strategy is effective. |
