随着国内外电力电子技术的发展，大量由电力电子开关构成且具有非线性特性用电设备的广泛应用，使得国内外电网中的谐波污染状况日益严重，谐波抑制和无功功率补偿的问题已成为电力系统迫切需要解决的问题。本文介绍了有源滤波器的发展史及其结构原理，对有源滤波器的关键技术进行了分析，并从海洋石油钻修井机实际应用的角度出发，结合有源滤波器在海洋石油钻修井机中的应用现状，对其前景进行了展望分析。%With the development of power electronic technology in the domesticand abroad, a large number of power electronics switch and extensive application of electrical equipment has a nonlinear characteristic, makes the situation of domestic and foreign power grid harmonic pollution increasingly serious, harmonic suppression and reactive power compensation issue become urgent to solve the problem of power system. This paper introduces the development history and structure principle of active power filter, the key technology of active power filter is analyzed, and from the practical application of drilling and workover machine of offshore oil, combines with active filter application status of workover rig drilling in offshore oil, the future prospect is analyzed.
