摘　　要：针对电动钻机动力系统非线性负载产生的谐波,分析了谐波对钻机井场电网的影响及其危害,提出了混合型有源电力滤波器(HAPF)方案,介绍了该系统的滤波原理、控制方法及对HAPF采用的复合控制策略。试验结果表明:HAPF对井场电网的谐波和无功具有较好的补偿效果,可有效提高井场电网功率因数,减少谐波电流,改善输出电流波形,且系统工作稳定可靠,性价比高,具有良好的工程推广应用价值。This paper presents a hybrid active power filter （HAPF） for suppressing harmonics caused by the nonlinear load in drilling rig electric system, and analyzes the impact and the harm of the harmonic.The principle and the control method of system are discussed.A composite control model is adopted.The experimental results show that the HAPF has the good characters of harmonics elimination and reactive power compensation, and the power factor is raised,the harmonic current is decreased and the current waveshape is improved;It is proved that the system works safety and steady and has good cost performance with deserving extensive use.
