Several variables in the lifting process affect the production level. Thevariable speed drive (VSD) enables the operator to control performance of the ESP system, changingthe speed of the motor installed at the bottom of the well, by making changes in the frequency.
Fluid production at the surface is affected to a large extent by the motor operation. Motors installedat the bottom may generate a maximum torque depending on the voltage applied to their terminalsat a given frequency. Due to the differences in fluid properties, it is necessary to vary the motorspeed in order to obtain the maximum torque; this is achieved by modifying the voltage applied atthe motor terminals. This is one of the reasons for using VSD in ESP systems.
Typically, VSD output voltages are lower than those required by the ESP system motor for optimaloperation. In addition, since the VSD operating frequency varies depending on the wellcharacteristics and, given that the VSD wave contains harmonics, use of a conventional transformeris not possible in these cases. For these reasons, a special step-up transformer must be used.[/vc_column_text][/vc_column][/vc_row]
