摘要
随着能源结构转型,对发电机组调峰调频能力提出了更高的要求.燃气-蒸汽联合循环发电响应快,更适应调峰调频需求.本文以燃气-蒸汽联合循环发电机组为例,研究其变工况条件下一次调频能力.搭建了联合循环发电机组模型,以评估环境温度、进气导向叶片(IGV)和工况变化对机组一次频率调节响应的影响.同时,研究了在不同发电负荷下,发电机组在一次频率调节过程中的性能表现.本研究为联合循环发电机组的调频控制提供了理论依据和技术支持.
Abstract
With the transformation of energy structure,higher requirements are put forward for the peak and frequency regulation ability of generator sets.Gas-steam combined cycle power generation has fast response and is more suitable for peak regulation and frequency regulation.In this paper,the gas-steam combined cycle generator set is taken as an example to study its primary frequency modulation capacity under variable working conditions.A combined cycle unit model was built to evaluate the effects of ambi-ent temperature,inlet guide vane(IGV)and operating conditions on the primary frequency regulation re-sponse of the unit.At the same time,the performance of the generator set in the primary frequency regu-lation process under different power generation loads is studied.This study provides a theoretical basis and technical support for the frequency modulation control of the combined cycle generator set.
