The present invention concerns an installation for pumping hydrocarbons, including a pump submerged in a well and a motor for driving the pump, said motor being linked to a variable frequency drive powered during normal operation by an external network, the drive including a rectifier supplying a DC bus, an inverter supplied by the DC bus and linked to the motor, and a controller, said installation wherein it further includes an electricity storage element linked by a reversible DC-DC converter to the DC bus, the installation being arranged to ensure the variable frequency drive is supplied by the storage element in case of an interruption to the supply via the external network.
An installation for pumping hydrocarbons, comprising:
An installation for pumping hydrocarbons, comprising:
An external safety module for an installation for pumping hydrocarbons comprising a pump submerged in a well, driven by an electric motor connected to a variable drive powered by the external network, this variable drive comprising a rectifier supplying a DC bus, an inverter powered by the DC bus and connected to the motor, and a controller, the variable drive comprising terminals for accessing the DC bus and a bus for data exchange with the outside, for transmitting information relating to the state of the external network and receiving a speed setpoint, the module comprising an electrical energy storage element, a reversible DC-DC converter and a control system for the converter, terminals to connect to the DC bus of the variable drive and a bus for communication with the variable drive for ascertaining the state of the network and transmitting to the variable drive at least one item of useful information for selecting a speed setpoint in case of emergency operation during a disruption of the network and/or for informing the variable drive of the charge state of the storage element.
A method for managing the power supply of an electric motor for driving a pump for pumping hydrocarbons, submerged in a well, belonging to an installation for pumping hydrocarbons, comprising:
