Improvement of 6/10 kV Distribution Power Networks Efficiency

The study focuses on the ways to improve the operation efficiency of 6 kV and 10 kV distribution power networks on the example of the Horodok District Power Network, Lvivoblenergo PJSC (Ukraine). The main drawbacks of these power networks are the poor condition of the electrical equipment and great length and insufficient transmission capacity of the existing 6/10 kV power transmission lines.

Effect of sucker-rod pumping unit walking beam oscillation frequency on asynchronous electric drive

The process of oil extraction requires continuous monitoring of oil wells operation. To improve the efficiency of oil wells, it is necessary to set the optimal mode of oil pumping unit operation in which the rate of liquid pumping corresponds to that of its inflow. Many oil wells are strippers and therefore are operated intermittently.
