20.500.12556/RUL-183583 Development of a mathematical model of the control system for a 6MW turbine-generator set Razvoj matematičnega modela krmilnega sistema za 6 MW turbinsko-generatorski sklop The stability of the rotation frequency of the synchronous electric generator as part of the turbinegenerator set is one of the most important indicators determining the quality of the electric power and its suitability for various consumers. Maintaining the rated frequency of the generator rotor spinning and, as a consequence, the frequency of the generated current directly depends on the balance between the mechanical power developed by the steam turbine and the electric power consumed by the load. The automatic control system must constantly adjust the power generated by the steam turbine by changing the steam supply to its blade system in order to maintain the frequency at a specified level. The paper identifies the still ignored features of the control system of the turbine-generator set rotation frequency and power using a mathematical model to obtain the data needed to design of the turbine set. The development of the interconnected mathematical models of the turbine set elements is described, i.e. the synchronous generator, steam turbine, chambers in the turbine steam path and the implementation of the turbine-generator set as a whole. The results of the computational experiments simulating the disturbing impact on the turbine-generator set are presented. Stabilnost frekvence vrtenja sinhronega električnega generatorja v turbinsko-generatorskem sklopu je ključni pokazatelj kakovosti električne energije in njene uporabnosti za različne porabnike. Ohranitev nazivnega vrtilnega momenta rotorja generatorja in s tem frekvence proizvedenega toka je odvisna od ravnovesja med mehansko močjo, ki jo razvije parna turbina, in električno močjo, ki jo porabi obremenitev. Avtomatski krmilni sistem nenehno prilagaja moč turbine z uravnavanjem dovoda pare, da ohrani frekvenco na želeni vrednosti. Članek s pomočjo matematičnega modela opiše še premalo raziskane značilnosti krmilnega sistema frekvence vrtenja in moči turbinsko-generatorskega sklopa ter opisuje razvoj povezanih modelov posameznih elementov sklopa (sinhroni generator, parna turbina, komore v parni poti) in simulacijo delovanja celotnega sistema. Predstavljeni so tudi rezultati simulacij, ki prikazujejo odziv sklopa na motnje. steam turbine synchronous generator turbine-generator set controlling system computer modelling computational experiment sinhroni električni generator kakovost električne energije vrtilni moment matematični model true false true Angleški jezik Slovenski jezik Članek v reviji 2026-06-15 15:00:13 2026-06-15 15:00:23 2026-06-16 04:04:32 0000-00-00 00:00:00 2025 0 0 Str. 288-299 št. 5 Letn. 92 2025 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.311:62-52 0013-5852 280556291 RAZ_Melnikov_Dmitrij_V._2025.pdf RAZ_Melnikov_Dmitrij_V._2025.pdf 1 BCAECCA2B0ACBE6B069EF3F543499F47 16a868bad5e53c245d135300e8c83e527df1c97d30187f084205fbe45496bb37 1f4018f0-68ba-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=235673 https://ev.fe.uni-lj.si/5-2025/Raevsky.pdf 0 3518f541-68ba-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=235674 Fakulteta za elektrotehniko 0 0 0
