Značajan dio bušaćih postrojenja koja su danas u upotrebi i dalje je opremljen mehaničkim sustavima upravljanja silom nasjeda bušaćeg alata (WoB) i njegovom brzinom prodiranja (RoP) zasnovanim na polužnom mehanizmu kočnice vitla dizalice koji

A notable portion of contemporary deep drilling rigs are still equipped with manually-operated lever-based draw-works (hoist) drum mechanical brake actuators, which are used for weight-on-bit (WoB) and rate-of-penetration (RoP) control. In order to m

Compared to interconnected power grids, islanded microgrids are more sensitive to active power disturbances due to lower specific rotational inertia and lack of spinning reserve. Because of these properties, islanded microgrid control and power quali

Many contemporary oil drilling rigs are still equipped with mature drilling equipment such as traditional speed-controlled top-drive units. Utilization of such “stiffly” controlled drilling drives, which do not account for drill-string compliance
