YNd7变压器差动保护d侧移相电流相位补偿方法
摘要：
本发明提供了一种YNd7变压器差动保护d侧移相电流相位补偿方法，其中，本发明提出一种对YNd7接线变压器差动保护装置d侧移相的电流进行相位补偿的方法，本发明通过先获取Y侧参与差动保护计算的电流，再基于获取Y侧参与差动保护计算的电流的相位，对d侧参与差动保护计算的电流进行软件移相，得到与Y侧参与差动保护计算的电流相位一致的d侧参与差动保护计算的电流相位，本方案获得了通过软件移相方法，快速、方便的对YNd7变压器差动保护进行电流相位补偿的技术效果。
摘要（英）：

The invention provides a phase compensation method for d-side phase-shift current of YNd7 transformer differential protection, and provides a phase compensation method for d-side phase-shift current of a YNd7 connection transformer differential protection device. Y-side current participating in differential protection calculation is firstly obtained, software phase shifting is carried out on d-side current participating in differential protection calculation on the basis of the phase of the obtained Y-side current participating in differential protection calculation, and the phase, which is consistent with that of the Y-side current participating in differential protection calculation, of the d-side current participating in differential protection calculation is obtained. According to the phase compensation method, the technical effect of quickly and conveniently carrying out current phase compensation on YNd7 transformer differential protection through a software phase shift method is obtained.
