  Transmission lines towers construction affects the line parameters and influences on its operation in the future. Misguided design of the tower can lead to serious problems such as overvoltages, electric arc extinction difficulties, voltage asymmetry, resonance phenomena or increasing of magnetic field near the line. The paper points out those threats on example of 400 kV double circuit overhead transmission line with shunt reactors....

  Cable lines are one of the basic components of power systems. Medium and high voltage cables mainly comprise a metallic sheath, which is concentric to the main core conductor. There are several operating schemes of such cable lines, which differ in the place of earthing of sheaths and the possible use of the sheaths and/or conductors crossing. The sheaths cross-bonding is typically done in two places of one cable line section,...

• On-Line Partitioning for On-Line Scheduling with Resource Conflicts

  Publikacja

  • P. Borowiecki

  - LECTURE NOTES IN COMPUTER SCIENCE - Rok 2008

  Within this paper, we consider the problem of on-line partitioning the sequence of jobs which are competing for non-sharable resources. As a result of partitioning we get the subsets of jobs that form separate instances of the on-line scheduling problem. The objective is to generate a partition into the minimum number of instances such that the response time of any job in each instance is bounded by a given constant. Our research...

  - Rok 2004

  W oparciu o metodę rodzajów sprzężonych przeprowadzono analizę macierzy rozproszenia sekcji ferrytowych linii szczelinowych (FLS). W oparciu o uzyskane wyniki opracowano model cyrkulatora zaprojektowany w postaci kaskadowego połączenia sekcji FLS oraz szczelinowego rozgałęzienia typu T. Określono parametry rozproszenia układu, które zweryfikowano eksperymentalnie.

  The paper presents resonance phenomena observed in 400 kV transmission lines in the Polish power system. Two events are analysed, when shunt reactors used for reactive power compensation, caused overvoltages and overcurrent protection tripping as a result of resonance. An oscillographic fault recordings from protection devices are compared to time domain simulation results. The obtained simulation results match fault recordings,...
