Abstract

Most geological drilling rigs using asynchronous motor with gear box as the drive device of drawworks have problems of instability at low speed, complex mechanism, and lots maintenance work. This paper proposes an application of permanent magnet synchronous motor (PMSM) used in drawworks. Firstly, running characteristics of PMSM in steady state are analyzed and calculated theoretically, and mathematical models of motor’s power, torque, and power loss are given. Secondly, vector control principle of PMSM is analyzed and introduced, and maximum torque/current control method is finally decided as the basis for the design of control system. Thirdly, running parameters of PMSM in three stages (lowering drill string, constant speed/pressure drilling, and lifting drill string) of each test point were measured, and the curves of key parameters of PMSM are given. Finally, it is concluded that drawworks with PMSMs can not only improve control performance, reduce power consumption, and save energy, but also omit the gearbox, which makes structure of lifting system more compact and reduce lots maintenance work. The research work of this paper lays a foundation for the popularization and application of PMSM in the industry of deep well drilling rig.
永磁同步电机在深井钻机提升系统中的应用及运行特性研究
大多数地质钻机采用带齿轮箱的异步电动机作为绞车的驱动装置,存在低速不稳定、机构复杂、维修工作量大等问题。介绍了永磁同步电动机在绞车中的应用。首先,对永磁同步电机稳态运行特性进行了理论分析和计算,给出了电机功率、转矩和功率损耗的数学模型。其次,分析和介绍了永磁同步电机的矢量控制原理,最终确定了最大转矩/电流控制方法,作为控制系统设计的依据。然后,测量了各试验点在下放钻柱、等速/压钻进和提钻柱三个阶段的PMSM运行参数,给出了PMSM关键参数曲线。最后得出结论,采用永磁同步电动机的绞车不仅提高了控制性能,降低了功耗,节约了能源,而且省去了齿轮箱,使提升系统结构更加紧凑,减少了大量的维护工作。本文的研究工作为永磁同步电机在深井钻机行业的推广应用奠定了基础。
