“…The first utilization of AMs with variable-frequency control in drilling rigs and common DC bus technology were both proposed at the same year by Abramov, et al 3,4 , which pointed the way for the development of modern drilling rigs. After that, the drilling rig BU-4200/250 based on variable-frequency technology with control system was manufactured 5 . However, intermediate deceleration mechanisms were still preserved because of the utilization of AM.…”

At present, the majority of deep borehole drilling rigs at home and abroad still utilize Asynchronous Motors (AM) with variable-frequency drive as the main power component, which cannot achieve stepless-speed adjustment without decelerating mechanism. In addition, the expenditure of lubrication and maintenance are usually high, and the transmission efficiency is not very ideal. Therefore, this paper proposes a permanent magnet electric direct-drive deep borehole drilling rig (DBZJ40-Z), which firstly adopts Permanent Magnet Synchronous Motor (PMSM) with variable frequency technique to achieve stepless-speed control and direct-drive method to remove the transmission mechanism. Owing to the higher power factor and efficiency of PMSMs, this new type of drilling rig proposed is more energy efficient than the conventional ones equipped with AMs. Furthermore, the utilization of direct-drive mechanism replaces the intermediate transmission gearbox to save a lot of cost of maintenance greatly. Advantages of this new deep borehole drilling rig equipped with PMSMs such as saving energy, easy to maintain and operate, etc. had been verified in several practical applications. Practices proved that this sort of permanent magnet electric direct-drive deep borehole drilling rig equipped with PMSMs must be the future for conventional ones.

“…Since 1960s, with rapid development of variable frequency control technology and the continuous maturity of motor technology, deep well drilling rig has been changed from old mechanical hydraulic transmission mechanism gradually developed to the variable frequency electric drive transmission mechanism. In 2009, Abramov et al 1 proposed the concept of electric variable frequency transformation of deep well drilling rig, and made a prototype (model: BU-4200/250). In their paper, the feasibility and realization principle of variable frequency electric drive technology of induction motor are expounded in detail.…”

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.

The relevance of the study lies in the search for energy-saving technologies. So, at present, the most common type of electric drive in industry is asynchronous, most of which are unregulated. Replacing an unregulated electric drive with an adjustable one in various units can significantly reduce energy consumption, increase the life of the mechanical part of the drive and improve the quality of the adjustable process parameter. The replacement consists in installing an electronic frequency converter between the network and the motor of the device. This device changes the rotational speed of the motor rotor by changing the frequency and amplitude of the supply voltage. The most common are frequency converters with an intermediate DC link. Such devices are built on electronic keys, which are made on IGBT (Insulated Gate Bipolar Transistor) transistors. Using the NI Multisim14 software, a model was created to determine power savings during the implementation of VFD.The paper gives the rationale for the introduction of a frequency-controlled electric drive (VFD) to optimize technological processes in electrical complexes and systems, in particular, a complete analysis of the energy efficiency of VFD application in pumped water supply systems is presented as an example. The calculation of its economic efficiency for a particular installation is also given.
