1. A system for controlling an electric submersible pump (ESP) motor, the system comprising:
an ESP having an electric motor;
an electric drive adapted to generate AC output power to drive the electric motor; and
an electrical network coupled between the electric drive and the electric motor, the electrical network including a filter, a transformer, and a transmission line;
wherein the electric drive includes
an output power generator adapted to receive external power from an external power source and to generate the AC output power from the received external power, and
a drive controller adapted to:
receive user input indicating one or more parameters of the ESP system, wherein the received user input comprises an identification of a motor parameter;
retrieve a table of electrical network parameters;
look up the identification of the motor parameter in the table;
build a model of the electrical network based at least in part on the one or more parameters of the ESP system and the set of the electrical network parameters;
receive real-time data indicating one or more current operating conditions of the electric motor;
generate a power adjustment parameter based on the model of the electrical network and the received real-time data indicating the one or more current operating conditions of the electric motor; and
provide the generated power adjustment parameter to the output power generator.
