论文摘要
在设计新的电力变压器时，需要可靠有效的工具来加快研发过程。其中一些工具用于解释从变压器测试获得的数据，以更好地判断变压器的响应。在本文中，提出了一个明确的程序来通过使用在线可测量数据来估算功率变压器的通量和激发电流之间的非线性关系，这是输入电流谐波的主要原因。结果表明，该过程以很高的精度计算这种关系，并与模拟中应用的结果相同。
In design of new power transformers, reliable and efficient tools are required to expedite research and development processes. Some of these tools are used to interpret the data obtained from the transformer tests for better judgement about the response of the transformer. In this paper a clear procedure is proposed to estimate the nonlinear relation between flux and excitation current of power transformers by using online measurable data, which is the main reason of the input current harmonics. It is shown that the procedure computes this relation with very high precision and leads to identical results to that applied in simulation.
