Power limiting control for multiple drilling rig tools

摘要

A power limiting control system includes at least one power generator configured to provide power to a plurality of tools on a drilling rig; and a power limiting controller configured to control the provision of power from the power generator to the plurality of tools. The power limiting controller is adapted to perform a method including determining an individual power consumption for each of the plurality of tools; calculating a total power consumption from each respective individual power consumption of the plurality of tools; comparing the total power consumption of the plurality of tools to a total available power; ranking each respective individual power consumption by load size; and reducing power consumption of at least one of the plurality of tools based on rank when the total power consumption exceeds the total available power.
