Electric Generating Systems

Where utility-furnished power is not available, generators may be used to provide electrical power required for operation of the pumping units. Technical Data used in the field explained in petroleum courses in Rawalpindi. This system allows the operator the benefits of electrification. When selecting equipment for the generating system, consider which type of motor will most efficiently use generator power. The ultrahigh-slip motors, which use fewer kilovolt amps (kVA) than conventional horsepower rated motors, are very popular. Distribution equipment for the generator system would be the same as for utility power if it were furnished. Some more details of petroleum courses in rawalpindi are as under.

Generated voltage depends on the size of the electrified field. The following considerations determine the most desirable generated voltage.  Where the system consists of a small number of wells (one to five) with short distances from generator to well site. the generator voltage may be the same as the  motor rated voltage. Where the field consists of many (5 to 50) wells, the distribution voltage should be higher than the motor rated voltage to minimize voltage drop. At each motor, a step down transformer would be used. This system would be considered a moderately sized system with a generator having a distribution of 2.300 or 4,160 V. 3. In an exceptionally large field (50+ wells), the generator voltage would be stepped up to 7,200 or 13.800 V for distribution. At each wellsite, a transformer would be installed to drop the distribution voltage to motor rated voltage. The generated voltage could be 2,300 or 4.160 V. The higher voltage allows smaller conductors to carry  the loads and lessen line drop voltage within acceptable limits.

The procedure used in selecting primary and secondary equipment should be the same as that used by the utility companies. Protective devices and grounding procedures outlined in this chapter apply to either system.
