Disclosed are a method and system for monitoring and controlling the normally inaccessible dynamic operating conditions, such as well fluid head and motor terminal voltage, of a well pumping operation, in response to monitored conditions at the top of the well. At the heart of the system is a computer having, stored therein, coded data representative of the fixed well, motor, and pump characteristics and programs defining the mathematical relationship between the stored fixed data, dynamic operating conditions of interest, and the monitored conditions. Feedback control for regulating the well fluid head and motor terminal voltage include the computer and uniquely designed frequency converter and line drop compensator apparatus.
