The elevated configuration of a steam turbine generator set represents an innovative paradigm for coal-fired power generation,markedly deviating from the spatial structure inherent in conventional coal-fired units.In order to ensure and elevate the performance of the cooling water system for high-level arrangement auxiliary machinery,the auxiliary machinery cooling water system was classified into four interrelated subsystems based on functional and layout considerations.Requiring the utilization of APROS software,a meticulous model of the auxiliary machinery cooling water system was established.Subsequent to an optimization of the high-level arrangement auxiliary machinery cooling water system,a rigorous quantitative comparison and dynamic characteristic analysis were conducted between the original and enhanced systems.Outcomes delineate that the improved system effectuates a reduction in auxiliary machinery operating temperatures,with peak node temperatures consistently maintained below 65 ℃,thereby substantially amplifying cooling reliability.
