摘　　要：对某电厂1000 MW机组凝结水管系进行了优化布置,建立了凝结水管系的应力力学模型和一维流动阻力模型,查明了管系的应力分布和流动阻力分布规律。结果表明:管系优化布置方案的管道在设计条件下具有足够的柔性,并且减少了管系的局部流动阻力。机组满负荷运行时,凝结水管系的流动阻力可降低约20%。The optimal layout of the condensate piping system of a 1000 MW unit was carried out.The stress mechanical model and one-dimensional flow resistance model of the condensate piping system were established.The distribution of the stress and flow resistance of the piping system were found out.The results show that the pipeline with the optimal layout scheme has enough flexibility under the design conditions,and the local flow resistance of the piping system is reduced.When the unit operates at full load,the flow resistance of the condensate piping system can be reduced by about 20%.
