变压器联结组标号的选择原则
Title: Principles for Selecting Transformer Connection Group Labels Transformer connection group labels are crucial in power systems, determining their performance and compatibility. 选择变压器联结
组标号在电力系统中至关重要，它决定了变压器的性能和兼容性。

Firstly, the selection should be based on the phase displacement between the primary and secondary windings. 首先，选择应基于初级绕组和次级绕组之间的相位位移。

Secondly, the voltage relationship between windings is another key factor. 其次，绕组之间的电压关系也是另一个关键因素。

The desired power flow direction within the system also influences the choice. 系统中所需的功率流向也会影响选择。

Moreover, the type of load connected to the transformer must be considered. 此外，还必须考虑连接到变压器的负载类型。

Safety and reliability requirements are paramount in determining the connection group. 安全性和可靠性要求在确定联结组时至关重要。

The operational flexibility of the transformer should also be taken into account. 同时，还应考虑变压器的操作灵活性。

Compatibility with existing system components is essential for seamless integration. 与现有系统组件的兼容性对于无缝集成至关重要。

Lastly, economic considerations, such as cost and efficiency, are vital in making the final decision. 最后，经济因素，如成本和效率，
在做出最终决策时至关重要。

In summary, selecting transformer connection group labels involves a multifaceted analysis, balancing technical requirements, safety considerations, and economic feasibility. 综上所述，选择变压器联结组标号涉及多方面的分析，需要平衡技术要求、安全考虑和经济可行性。

By adhering to these principles, a suitable connection group can be chosen to ensure optimal transformer performance and system reliability. 遵循这些原则，可以选择合适的联结组，以确保变压器的最佳性能和系统的可靠性。
