The reactive power compensation of the industrial consumer
Pospíšil, Zdeněk ; Holoubek, Jiří (referee) ; Toman, Petr (advisor)
This bachelor thesis deals with the reactive power compensation. The reactive power compensation falls into an important measures reducing current load of electrical grids and other equipments, which increase its lifespan and decrease energy losses. The bachelor thesis is divided into a theoretical and a practical part. In the theoretical part is explained the theory necessary for good understanding of compensation, explained the sanctions and the additional fees for unsatisfactory power factor and summarized the impacts of compensation on the electrical network. Further is shown the basic classification of compensation by its place of connection, type of compensation device and regulation. The end of theoretical part is dedicated to the simple calculation of compensation. The practical part deals with the real design of the reactive power compensation for a particular industrial consumer.

The reactive-power compensation of the industrial consumer
Mišinger, Ondřej ; Bok, Jaromír (referee) ; Toman, Petr (advisor)
The work deals with reactive-power compensation (power factor correction = PFC) at low and medium voltage. The theoretical part is focused on explaining the basic concepts of power factor correction and the reasons why the PFC is made. There is stated the basic allocation of PFC. Attention is devoted mainly for detuned PFC, which is nowadays often used because of the large number of nonlinear loads installed by customers. There are listed also the basic computational relations. Moreover, there are described the basic elements of compensation devices, which are capacitors, detuning reactors, contactors and power factor regulators. The practical part is dealt with power factor compensation for a particular industrial customers. There are offered several variants of the technical implementation of the PFC. These various options are compared from both technical and economic terms.

Reactive Power Compensation of The Industrial Consumer
Hanzelka, Jiří ; Holoubek, Jiří (referee) ; Toman, Petr (advisor)
This thesis is focused on reactive power compensation and it suggests new conceptions for industrial customers. The first part describes the basics of compensation, location and ways of compensation. In conclusion of this part it is a good example of parallel reactive power compensation. The second part deals with the design of reactive power compensation specifically for raw water pumping station. Compensation was solved both on a low voltage level and on the high voltage level. For drawings were used program EPLAN Electric P8.

Reconfiguration of an industrial distribution system including local power source integration
Benetka, Tomáš ; Holoubek, Jiří (referee) ; Drápela, Jiří (advisor)
This bachelor´s thesis deals with reconfiguration of industrial network that has been technologically reconstructed. The aim of this study is mostly to describe changes made on devices used for reactive power compensation and improving the power quality. Thesis is divided into two parts. Theoretical part of thesis deals with parameters used for judging power quality and causes of changes for these parameters, eventually with devices for its adjustment. Standard demands for these parameters are also included. Further, reactive power compensation, extract of reactive power appliance and their influence on power network is described in this thesis. In the second - practical - part devices used for reactive power compensation were reconstructed. This part is also focused on local energy source integration and usage of power electronic engineering products for power quality provision.

The reactive power compensation of the industrial consumer
Doseděl, Tomáš ; Martinák, Rostislav (referee) ; Toman, Petr (advisor)
This thesis is about reactive-power compensation used in real practise. In theoretical part, basic principles of reactive-power compensation are stated. Also, charges for breaching power factor and overview of individual compensation components are dealth with. Practical part is about the design of a low voltage compensator for industrial customer.Compensator uses central compensation with gradual switching.

Reactive power compensation of electrothermal devices
Tomeš, Martin ; Paar, Martin (referee) ; Lázničková, Ilona (advisor)
The work deals with reactive-power compensation (power factor correction = PFC) in practice. The theoretical part describes the basic concepts of power factor correction, reasons for the PFC, and the ways of the PFC, eventually a sanction for a breach of rated power factor. Attention is given to basic partition of the PFC and compensation devices which are capacitors and detuning reactors. The practical part is focused on the PFC analysis for a concrete customer where the central compensation is projected. The practical part is also focused on a detuned power factor correction which is often used by reason of increases in number of nonlinear loads nowadays.
