摘要:
 针对粒子群算法在求解油纸绝缘等效电路模型参数过程中容易陷入局部最优的问题,结合
混沌理论提出一种油纸绝缘极化等效电路参数计算方法。根据混沌算法具有遍历性和不重复性的
特点,在粒子群算法中加入混沌扰量,使得算法不陷入局部最优解,从而辨识油纸绝缘等效电路参
数。计算结果表明,应用混沌粒子群改进算法获得的回复电压极化谱能够很好地与现场测试得到
的回复电压极化谱相吻合。通过所提算法求解得到的油纸绝缘等效电路模型能够准确地反映油纸
变压器的绝缘状况,为后续诊断油纸绝缘的老化情况奠定重要基础。
Abstract:
 Aiming at the problem of the particle swarm algorithm easily into the local optimum in the
process of solving oil-paper insulation equivalent circuit model parameters,a new method of calculating
the oil-paper insulation equivalent circuit parameters was proposed combined with the chaos theory. According
to the chaos algorithm characteristics of ergodicity and no repetitiveness,combining the chaos disturbance
with the particle swam algorithm,which does not fall into local optimal solution,oil-paper insulation
equivalent circuit parameters was identified. The calculation results show that the return voltage polarization
spectrum obtained by improved particle swarm optimization algorithm can be matched better with
the return voltage polarization spectrum obtained by field test. The oil-paper insulation equivalent circuit
model based on the new algorithm can reflect the insulation condition of oil-paper insulation transformer
accurately,which laid an important foundation for the subsequent diagnosising oil-paper insulation aging.
