基于小型风力发电机组的AT所配电技术研究

摘要

Introduction was made to the auto-transformer(AT) substation of traction electric network and its power distribution system’s working principle. Combined with the characteristic of AT substation, this paper gave a set of power distribution design plan to use minitype wind power generating set as the backup power supply and analysis investigation was made to the control strategy of maximum power opera-tion of wind power generating set and the grid-connected control strategy. The quality and stability of power distribution in AT substation of traction electric network was improved.%介绍了牵引网自耦变压器(AT)所及其配电系统工作原理，结合AT所特性给出了一套以小型风力发电机组作备用电源的配电设计方案，并分析研究了风电机组最大功率运行的控制策略及并网控制策略，改善了牵引网AT所配电电能质量及其稳定性。
