Abstract

Kut opterećenja sinkronog generatora pogonska je veličina koja daje direktnu
informaciju o položaju radne točke generatora s obzirom na granicu stabilnosti. Budući
da rad elektroenergetskog sustava karakteriziraju velike promjene pogonskog stanja
rada sinkronog generatora, a prijelaz iz jednog u drugo pogonsko stanje najčešće prate
značajne dinamičke promjene kuta opterećenja. Zbog toga je za upravljanje i zaštitu
sinkronog generatora vrlo važno poznavati kut opterećenja.
U ovome radu opisan je način mjerenja kuta opterećenja pomoću enkodera
montiranog na osovini rotora sinkronog generatora i pomoću logičkog kontrolera NI
CompactRIO-9022 s dodatnim modulom NI-9411. Osim toga dato je još nekoliko
primjera mjerenja kuta opterećenja direktnim i indirektnim metodama. U sklopu ovoga
rada izrađen je algoritam za mjerenje kuta opterećenja sinkronog generatora, a izrađen
je pomoću programskog alata LabVIEW i modula LabVIEW Real-Time. Izrađeni
algoritam detaljno je opisan i na kraju rada su prikazani rezultati simulacije istog.

Abstract (english)

The load angle of a synchronous generator is a drive quantity that provides direct
information about the position of the generator operating point with respect to the
stability limit. Since the operation of the power system is characterized by large
changes in the operating state of the synchronous generator, the transition from one
to another operating state is usually followed by significant dynamic changes in the
load angle. Therefore, it is very important to know the load angle to control and protect
the synchronous generator.
This paper describes a method of measuring the load angle using an encoder mounted
on the rotor shaft of a synchronous generator and using a logic controller NI
CompactRIO-9022 with an additional module NI-9411. Additionally, several other
examples of direct and indirect load angle measurements are provided. As part of this
work, an algorithm for measuring the load angle of a synchronous generator was
developed using the LabVIEW software tool and the LabVIEW Real-Time module. The
developed algorithm is described in detail and at the end of the paper, the results of
the simulation are shown.
