INSTALLATION FOR PUMPING HYDROCARBONS, MODULE AND METHOD

摘要

The present invention concerns an installation (1) for pumping hydrocarbons, comprising a pump (P) submerged in a well (W) and a motor (M) for driving the pump (P), said motor (M) being linked to a variable frequency drive (2) powered during normal operation by an external network (A), the drive (2) comprising a rectifier (4) supplying a DC bus (11), an inverter (3) supplied by the DC bus (11) and linked to the motor (M), and a controller (8), said installation (1) being characterised by the fact that it further comprises an electricity storage element (5) linked by a reversible DC-DC converter (6) to the DC bus (11), the installation (1) being arranged to ensure the variable frequency drive (2) is supplied by the storage element (5) in case of an interruption to the supply via the external network (A).
