The present subject matter generally relates to a submersible pumpset. The submersible pumpset is drive by electricity configured to engage with the magnetic rotor, wherein the said submersible pump using variable frequency drive (VFC), and wherein motor of said submersible pump works on magnetic ...
However, where varying output is needed, a variable frequency power supply may be used (Section 19.24), although at significant extra cost. If there is any risk that inflow to the borehole could be predominantly from a higher level than the pump inlet, or if the pump is installed in a ...

摘要：An electric submersible pump (ESP, 22) control system (36) includes a primary variable frequency drive (VFD, 38), a transformer (42), and a secondary VFD (44). The primary variable frequency drive (VFD) is configured to receive power from a power source (34) and output a variable...
variable speed drive(VSD) technology can effectively broaden high efficiency range of pump and benefit to energy saving and decrease energy consumption to ensure the pump lifting.But raising the frequency can increase the load-power of pump much faster than the output-power of motor.For the motor...
Practical results for the ESP system have also been shown in a reliable way for other variable frequency drive (VFD) topologies (Demmig et al., 2011; Raad et al., 1996). Most of the above-mentioned works just addressed the subject separately, which may not be the appropriate way to ...
