航天器光伏电池故障诊断及仿真

摘要

The spacecraft fault diagnosis method of photovoltaic cells is studied to detect the fault point .Wavelet trans‐form method is used to analyze photovoltaic battery point of failure .The noise conditions for fault signal are denoised .Many kinds of wavelet basis function test spacecraft photovoltaic cell mutation point are combined .The simulation results show that the spacecraft is the abrupt change point of the pv cells detect spacecraft photovoltaic battery failure point ,proves the feasibility of this method .%论文研究了航天器光伏电池故障诊断方法检测出故障点的问题。用小波变换方法分析光伏电池故障点；对噪声干扰情况下的故障信号进行消噪处理；结合多种小波基函数检测航天器光伏电池突变点；仿真结果表明航天器光伏电池测出的突变点就是航天器光伏电池故障点，证明了该文方法的可行性。
