Compensation of Voltage Loss in the Power Line

Abstract

The method of compensating voltage loss in the electrical network providing high power load are considered. Compensation is achieved by maintaining a capacitive (or inductive) current in the supply network using the high speed compensating device. The required value of current is determined by the compensator by calculations based on measurements of the active and reactive load current and load voltage in the node. Active and inductive impedance supply mains assumed to be known or identified in the process. The equations for calculating currents in the power supply system for a variety of modes are proposed.

“…However, a top-down analysis based on the law (2), which is used to describe POS of the systems in case of sudden failures, is valid, for example, for radio-electronic devices [10], whose structural elements are very complex products -subsystems of the lower level. But at the level of components of a mechanical system (MS) [11], degradation failures due to metal fatigue, wear, corrosion, and aging of materials are not described by the exponential law (2), hereat its application in these cases is incorrect.…”

“…Application of the exponential law expression (2) does not provide simple options for a top-down circuit analysis, both for the relations (10,11) and for more complex structures with concurrent interaction of elements (with switches, element redundancy and circuits, etc.). Perhaps for this reason, examples of a top-down circuit analysis of such structures are not given in the literature.…”

“…After solving the equation (27) with respect to t given in [9,10], we obtain the lifetime distribution function depending on the given POS:…”
