ANALYTICAL SOLUTION FOR THE PROBLEM OF WAVE PROPAGATION IN THE LONG LINE LOADED WITH CAPACITY, RESISTANCE AND INDUCTANCE
Authors: Patsuk V.I.
|
| |
Abstract: It was obtained the exact analytical solution for the problem of wave propagation in the ideal single-wire line, loaded with capacity, resistance and inductance on the receive end. The solution was obtained through Riemann invariants. It was elaborated the program of symbolic computing in the system MatLab for the automation of voluminous analytical transformation. |

Authors: Lupushor Irina
|

Abstract: The problems of the optimization reliability in electrical networks of the different class of voltage have probabilistic nature, they discretely change and depend on the number of factors both definite and indefinite and have importance by selection of electric equipment, graph of development of electrical networks and voltage levels. The definition of the major factors, which have determining significance on their value and speed of their change allow to elaborate methods of their optimization and to elaborate effective methods of their growth limitation in electrical networks with the different class of voltage. |

Minimization of unevenness of the loading of the selfcompensating high voltage power lines
Authors: Suslov V.M., V.M. Postolati,
|
| |
Abstract: For minimization of unevenness of the loading the chains operated selfcompensating high-voltage power lines (OSHPL) in process of management of its reception capacity by means of synchronous change the angular shift of the phases of the voltage vector systems of the chains on its both sides is offered hereto process to add the additional regulation on sending end of the line. The Analytical way is determined criterion this additional regulation. In addition notion of the quasiwave mode OSHPL is determined for free angle of the shift of the phases of the voltage vector systems of its chains.Key word: power line, angular shift of the phases. |
