SYSTEM, METHOD AND APPARATUS FOR COMPUTING, MONITORING, MEASURING, OPTIMIZING AND ALLOCATING POWER AND ENERGY FOR A ROD PUMPING SYSTEM

摘要

A system and methods are provided for controlling a motor of a rod pumping system using previous RPMs of the motor and predicting an RPM of the motor; correcting a power factor of a motor of a rod pumping system; allocating energy consumption and allocating energy generation for a set of wells connected to an electricity meter using an amount of energy generated by each well; and generating an alert if a set of data is beyond a threshold for the set of data.

主权项

1. A method for controlling a motor connected to a rod pumping system and switchably connected to a voltage supply, utilizing an energy monitoring device connected to the motor and the voltage supply, the method comprising the steps of:
determining a last RPM pulse of the motor; measuring a new RPM pulse of the motor; calculating an instant RPM from the new RPM pulse and the last RPM pulse; measuring a present frequency of the voltage supply; calculating a motor synchronous speed from the present frequency; and, determining a switch command based on the instant RPM and the motor synchronous speed.
