| 摘 要： | 为了提高备自投装置的自适应性，改善其性能，根据智能变电站的技术特点，提出一种基于站域信息的备自投构建方法。该方法将整个变电站内的备自投功能用一套装置集中实现。通过构建基础备自投单元，并对其进行信息配置和合理组合，可满足不同接线方式下备自投的应用要求。综合利用支路开关状态信息和电流信息，对变电站运行方式进行在线辨识，据此对备自投功能进行调整，以提高备自投装置的自适应能力。此外，利用站域信息共享的技术优势，优化站内不同备自投间的配合，提高不同运行工况下的备自投性能。数字仿真结果验证了所提方法的有效性。

| Abstract: | In order to improve the adaptability and performance of automatic bus transfer equipment, a method of automatic bus transfer based on substation area information is proposed according to the technical features of intelligent substation. Based on basic configuration unit of automatic bus transfer and its information configuration and reasonable combination, the automatic bus transfer equipment can meet the application requirements under various connection modes. Through using branch switch state information and current information, the operation mode of substation can be identified online. According to the result of online identification, the automatic bus transfer function is adjusted to improve the adaptability. In addition, the coordination between different automatic bus transfer and the performance of automatic bus transfer device can be improved by using the technical advantages of substation information sharing. The correctness of the method is verified by digital simulation. |
