3-phase Power Factoctor Corrector Units for Laboratory Training
Plucnara, Roman ; Paar, Martin (referee) ; Drápela, Jiří (advisor)
The aim is to describe the issue of compensation factor. The thesis describes the methods and individual implementation of compensation unit from rotating compensators, used until now protected compensation section and active filters. It also describes the influence of processing and elimination of higher harmonics present in the compensated circuits. The following are simple phasor diagrams and relevant patterns. The practical part shows these preconditions used to create laboratory exercises. Individual solve specific practical task illustrate the importance of reactive power compensation is using sophisticated, compensation elements used, for example, reactive power regulators. It reflected the simplest possible compensation the power factor, using the manual switching of capacitor banks.

Design of reactive power compensation in distribution network
Popek, Jiří ; Holoubek, Jiří (referee) ; Lázničková, Ilona (advisor)
This thesis is about reactive power compensation in industrial network. Task is design reactive power compensation devices, so that the power factor, which is main indicator of power quality, was within the limits required by the distributor. This is applied to wholesale customers of electrical energy. Reactive power consumed by appliances increased the current that flows through the network, transmission losses and voltage drop. Reactive power compensation is a measure reducing load current and ohmic losses in a supply line. Given that the compensation is one of the significant cost-saving measures in electric power distribution. Distributor requires electric power consumption with a lagging power factor in the range from 0,95 to 1. Other values of power factor are penalized.

Reactive power compensation in Petrochemie company using a passive power factor correction system instead of synchronous generators
Martinák, Rostislav ; Žila, Drahoslav (referee) ; Drápela, Jiří (advisor)
This thesis deals with the reactive power compensation, namely the possibility of reactive power compensation in Petrochemie company using a passive power factor correction system instead of synchronous generators, as part of the contract Kompel company. The thesis analyzes problems of definition of power in circuits with sinusoidal and nonsinusoidal voltages and currents. Furthermore, this thesis describes the power factor correction systems used in the low and medium voltage industrial and distribution networks. The last four chapters contain description of the existing state of power plant in Petrochemie company. There are considered the possibility of use of existing power factor correction system owned by company. The new static power factor correction system is suggested and functionality of power factor correction systems is verified through the simulations.
