摘　　要：为实现避雷器的在线监测,提出一种基于微弱信号的避雷器运行在线感知方法。方法首先采用变分模态分解算法(Variational Mode Decomposition,VMD)对避雷器运行的微弱电流信号进行去噪处理,然后在粒子群优化算法(Particle Swarm Optimization,PSO)中引入量子理论进行改进,最后基于改进的PSO算法求解可反映避雷器运行状况的等效电容C、非线性系数k、α参数,并根据参数变化判断避雷器运行情况。仿真结果表明,所提方法实现了避雷器运行在线感知,且受谐波电压和电压频率波动的影响较小;相较于GA算法和BTO算法,所提方法的仿真结果与实际结果更接近,具有一定的优越性,为避雷器运行在线感知提供了参考。To achieve online monitoring of lightning arresters,a weak signal based online perception method for lightning arrester operation is proposed.The method first uses the Variational Mode Decomposition(VMD)algorithm to denoise the weak current signal of the lightning arrester operation.Then,quantum theory is introduced into the Particle Swarm Optimization(PSO)algorithm to improve the PSO algorithm.Finally,based on the improved PSO algorithm,parameters that can reflect the operation status of the lightning arrester,including equivalent capacitance C and nonlinear coefficient k,are solvedα,And judge the operation of the lightning arrester based on parameter changes.The simulation results show that the proposed method can effectively achieve online perception of lightning arrester operation,and is less affected by harmonic voltage and voltage frequency fluctuations.Compared to the GA algorithm and BTO algorithm,the simulation results of the proposed method are closer to the actual results and have certain advantages,providing a reference for online perception of lightning arrester operation.
