In steam power plants condensers, the condensation heat of the steam is removed to the environment. The geometry (heat transfer surface area, tube diameter) and the operating conditions of the steam condensers influence the power plant performance (power and efficiency). As the diameter of the steam condenser tube changes, the heat transfer conditions and the cooling water flow resistance change, which translates into the pressure of condensing steam, the power generated by the turbine, the power needed to drive the cooling water pump and the power plant efficiency. Due to the extension of the operating time of 200 MW class power units and their greater flexibility of operation in the power system, the article verifies the selection of the diameter of the steam condenser tube in order to investigate the possibilities of improving performance. The 200 MW unit model was created in the Ebsilon program. The optimization criterion is to maximize the power and net efficiency of the unit.
