Análisis de la redundancia en la generación de vapor con parámetros inferiores en un monobloque de 64 MW // Analysis of redundancy in the steam generation with inferior parameters in an unit of 64 MW.
Abstract
La necesidad del país de mantener la generación eléctrica a fin de evitar los cortes de servicio planificados e imprevistos,
debido a la difícil situación económica actual, obliga a buscar soluciones que al menos sirvan de paliativo temporal a esta
desagradable situación. En una central termoeléctrica ubicada en el perímetro de la ciudad, se presentó la situación de que
producto de un accidente, un bloque quedó sin turbogenerador, estando su generador de vapor en magníficas condiciones
de explotación; y que otro bloque presentaba muchas salidas forzosas fuera de servicio producto de una insuficiente
reparación de su generador de vapor. La carencia de fondos para acometer una efectiva reparación, hizo pensar en el
análisis de la posibilidad de utilizar la caldera de una unidad para alimentar el turbogenerador de la otra. En el presente
trabajo se muestran los cálculos correspondientes para determinar aproximadamente el comportamiento de la turbina en las
nuevas condiciones impuestas, se realizó un análisis de fiabilidad del sistema propuesto y se utilizó la simulación como
herramienta para modelar el proceso.
Palabras claves: centrales termoeléctricas, fiabilidad, eficiencia, turbina de gas, caldera.

Abstract:
The necessity of Cuba to maintain the electric generation in order to avoid the interruption of service in planned or
accidental way, due to the difficult current economic situation, forces to solutions that at least serve for temporary palliative
to this unpleasant situation. In a thermoelectric power station located in the perimeter of the city, a situation was presented
due to an accident, a block with fail in the turbogenerator and the steam generator in good conditions of exploitation; and
that another block, the No.7, presented many mandatory out of service product of an insufficient repair of its generator.
This situation lead to analyze the possibility of use the boiler of one unit to feed the another one turbogenerator. In the
present work, the corresponding calculations to determine the behavior of the turbine under the new imposed conditions
are shown, it was carried out an analysis of reliability of the proposed system using the simulation like a tool for modeling
the process.
Key words: thermoelectric plant, reliability, efficiency, steam turbine, boiler.
