摘要
为研究特快速暂态过电压(VFTO)对大型电力变压器绕组绝缘的影响,首先基于短路导纳参数计算VFTO作用下绕组的电压传输函数,然后用人工鱼群与蛙跳混合算法改进的矢量匹配法实现电压传输函数的有理拟合,最后用网络综合技术实现过电压分布的计算。结果表明,该方法不仅具有快速全局搜索的特点,且提高建模精度达15. 7%。
To study the effect of Very Fast Transient Over-voltage( VFTO) on the insulation of large power transformer windings. Firstly,the voltage transfer function of the winding under VFTO is calculated based on the short circuit admittance parameters. Then,the vector fitting method of a hybrid artificial fish and frog leaking algorithm is used to realize the rational fitting of voltage transfer function. Finally,the calculation of over-voltage distribution is realized by network synthesis technique. The results show that the proposed method not only has the characteristics of fast global search,but also improves the modeling accuracy by 15. 7%.
