基于磁流变阻尼器的变压器半主动减振控制研究
Research on Semi-Active Damping Control of Transformers Based on Magnetorheological Dampers
摘要: 变压器在运行时自身振动和受到的环境扰动，会导致变压器本体部件的松动，影响变压器正常运行，当前对变压器振动的分析及减振研究受到了广泛关注。本文将磁流变阻尼器(magneto-rheological damper, MRD)运用到变压器减振中，设计变压器半主动减振系统和MRD控制算法，在内部和外部激励作用，对比分析不同控制算法下对变压器振动加速度的减弱。仿真结果表明，在不同激励作用，与不加控制情况相比，开关控制最大实现了对振动加速度26%减弱，改进型模糊开关控制在开关控制的基础之上对振动加速度实现了17%的减弱。
Abstract: The transformer itself vibrates and is disturbed by the environment during operation, which can lead to the loosening of the transformer body parts and affect the normal operation of the trans-former. The analysis of transformer vibration and damping research is currently receiving a lot of attention. In this paper, magnetorheological dampers are applied to transformer damping to design a semi-active damping system for transformers and MRD control algorithm to compare and analyze the damping of transformer vibration acceleration under the action of internal and external excitation with different control algorithms. The simulation results show that under different excitation, compared with the case without control, the switching control can reduce the vibration acceleration by 26%, and the improved fuzzy switching control can reduce the vibration acceleration by 17% based on the switching control.
