摘要: 为了揭示大型超超临界机组高中参数供热综合性能特征，本文选取某1000 MW一次再热超超临界机组为分析对象，构建了高精度热力系统仿真模型，并对不同机组参数下供热综合性能进行了分析。仿真结果表明，在大型超超临界机组参数一定的前提下，提升主蒸汽有效温度和再热处理蒸汽有效温度能够提升系统的热适用性，提升主蒸汽有效温度造成的收益高于再热蒸汽有效温度变化带来的收益，提升主蒸汽压力更有助于机组能耗、煤耗的降低。
Abstract: In order to reveal the comprehensive performance characteristics of high and medium parameter heating in large ultra supercritical units, this paper selects a 1000 MW once reheat ultra supercritical unit as the analysis object, constructs a high-precision thermal system simulation model, and analyzes the comprehensive heating performance under different unit parameters. The simulation results show that, under the premise of certain parameters in large ultra supercritical units, increasing the effective temperature of the main steam and the effective temperature of the reheated steam can improve the thermal applicability of the system. The benefits caused by increasing the effective temperature of the main steam are higher than those caused by changes in the effective temperature of the reheated steam. Increasing the main steam pressure is more conducive to reducing the energy and coal consumption of the unit.
