长链式电网分接头确定原则及其在南疆电网中的应用

General Principles of Transformer Tap Determination in Long-chain Power Grid and Its Application to South Xinjiang Power Grid

长链式电网电压控制问题较为突出,合理的分接头位置有重要意义。结合长链式电网运行特点,分别从大小负荷方式、事故后方式、检修方式和空充线路控制方面分析变压器分接头位置对电压控制的影响,综合四个方面下的电压控制找出最优的分接头位置,并将此方法应用到疆南电网库—阿—巴—喀工程。结果表明,采用分接头确定方法能够满足电网运行要求,对实际电网运行有一定参考意义。

The voltage control of lone -chain power grid is more prominent, and the reasonable tap position is very important. Based on the operating characteristics of long - chain power grid, the influence of transformer tap position on voltage control is analyzed in four ways, and the optimal tap position is found out comprehensively from view of four voltage controls. The practi- cability and accuracy of the proposed method are analyzed by an actual power grid. The results show that the proposed method can meet the requirements of power grid operation and it provides a valuable reference to the actual power grid operation.
