(Avtor) steam turbinesynchronous generatorturbine-generator setcontrolling systemcomputer modellingcomputational experimentThe 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.20252026-06-15 15:00:13Članek v reviji183583sl
