热电厂利用余热发电对厂用电系统的影响分析

The analysis of the influence of waste heat power generation on the auxiliary power system in the thermo-eletric plant

本文简述了热电厂利用余压余热发电的工作原理,在发电机选型、容量选择和接入高压厂用母线并网运行过程中对厂用电系统安全运行可能产生的影响方面进行了分析,并在发电机选型和参数选择方面提出了建议,确保新增加电机后不影响厂用电系统安全稳定运行。最后结合工程实例进行了计算和分析。

This paper briefly indicate the operational principle of residual heat power generation in the thermo-eletric plant. And the same time, the selection method of the generator and the capacity is discussed in detail. Furtherly the possible consequence of the electrical connection schemes for the safa operation of the auxiliary power system is the focus of the statement. Then some suggestions on selection of generator and parameters are put forward. At the end of this paper, the stable operation of the auxiliary power system is guaranteed by the analysis and calculation of the combination engineering case.
