Abstract

It is shown that, to calculate the installed capacity of a network storage device for drilling rig objects, it is necessary to build a load graph—the dependence of the supply network voltage as a function of time. This graph can be calculated on the basis of statistical data of possible and permissible voltage dips in time and depth. The proposed structure of the network drive can work as a part of both diesel-generator and gas-piston installations. The structure of the network storage of electric energy is presented using an example that contains the following enlarged nodes: cabinets with switching equipment, network-filter cabinets, a cabinet of semiconductor active rectifiers, electric-energy storage devices based on supercapacitors and lithium batteries, and a microprocessor control cabinet. A structure of network energy-storage devices containing an active rectifier is proposed in which it becomes possible to adjust the power factor of the system by influencing the control signals on the active and reactive components of the currents. It is shown that the proposed drive allows one to maintain failure of supply voltage for 10 s, provided that an installed power of the drive is selected equal to half of the total power of the installation. The developed structure can be turned on in parallel with renewable energy sources, and can also be used as a fast charging station for electric vehicles.
