Mathematical model of the steam-water cycle for CHP unit with bleed-condensing turbine

摘要: The diagnostics of operation for the energy conversion systems is realized as a result collecting, processing, evaluating and analyzing measurement signals. Thus, determination process state, understood evaluation hereof deviations from reference standard possible. Researches focused on identification states changes have been developed in processes. existing thermal diagnosis systems, which goal was operation, are enriched with modules, enable to localize causes excessive consumption. It requires application simulation models Additionally, simple short calculation time necessary needs. Such can be obtained utilization empirical modelling methods. Good results brings construction analytical model auxiliary functions built-in. paper presents mathematical steam-water cycle cogeneration heat power (CHP) unit bleed-condensing turbine containing mass balances equations describing steam expansion line transfer processes exchangers. Worked out contains partial turbine, exchangers condenser. Exemplary presented.
