  - Rok 2017

  In this work a heat balance was made for the nominal conditions of a block working with 18K370 turbine. For the parameters obtained, the thermal-flow calculations of the steam turbine were performed, maintaining the actual geometry of its flow system. Based on the nominal values obtained, iterative thermal and flow calculations were made for both the heat cycle of the power plant block and the steam turbine itself, seeking to obtain...

  - Rok 2011

  In the paper numerical simulations have been performed to predict the performance of the diferent steam models. All of the considered models of steam condensation have been validated on the base of benchmark experiment employing expansion in nozzle and next on the low pressure part of the steam turbine equipped with the so-called Baumann stage. For numerical analysis three models have been finally used - the ideal steam model without...

• Neural Modelling of Steam Turbine Control Stage

  Publikacja

  • J. Głuch
  • M. Drosińska-Komor

  - Rok 2021

  The paper describes possibility of steam turbine control stage neural model creation. It is of great importance because wider application of green energy causes severe conditions for control of energy generation systems operation Results of chosen steam turbine of 200 MW power measurements are applied as an example showing way of neural model creation. They serve as training and testing data of such neural model. Relatively simple...

• Proposition of the steam turbine governor structure modification

  Publikacja

  • Z. Lubośny
  • J. Klucznik
  • K. Dobrzyński

  - Rok 2014

  There is considered the steam turbine governor operation during defense and restoration of the power system. It points out weaknesses of currently used governor structures. The new controller is proposed, that takes advantages of those curently used. The new controller allows for more effective control of the turbine in emergency situations, at frequencies much different from the nominal value.

• Determination of Failure Causes of a Steam Turbine Casing

  • S. Topolska
  • M. Sozańska

  - Solid State Phenomena - Rok 2012

  The paper presents results of research and failure analysis undertaken to determine failure causes of a steam turbine casing. After 130,000 hours of service the crack in a outer shell of the turbine casing was found. The inner shell of the casing was made of cast steel grade G21CrMoV5-7, and the outer shell of grade G20CrMo4-5. Following research were performed in order to determine causes of the casing failure: chemical analysis;...

  • K. Kulkowski
  • M. Grochowski
  • K. Duzinkiewicz

  - Rok 2014

  The paper describes the approach to a Nuclear Power Plant steam turbine modelling which would enable on-line optimal process control (model based) and diagnosis over wide range of operating conditions caused by changing power demand. Presented model is static, multivariable and nonlinear. Such model enables analyzing the heat cogeneration aspects. Developed model is validated and verified by using archive data gained from researches...
