FIELD: oil and gas industry.
SUBSTANCE: invention relates to oil industry and is intended for elimination of asphalt-resin-paraffin deposits (ARPD) on walls of oil well tubing. Autonomous hybrid electrotechnical complex for control of ARPD in oil well consists of photoelectric system (PES) and wind electric plant (WES), output of which is connected to input of three-phase diode rectifier through power cable of alternating current. Outputs of the PES and three-phase diode rectifiers are connected to the DC bus, to which the DC cable is also attached, the second end of which is connected to the heating cable through the terminal block. System also includes a control and protection unit, to the input of which a temperature sensor is connected, located directly in the tubing. System of contactors installed in WES and PES generation circuits is connected to outputs of control and protection unit.
EFFECT: putting into operation of photoelectric system complex as additional electric power generator and control and protection unit intended for complex operation control.
