摘要: |
为了弥补国内对燃气-蒸汽联合循环电厂(Combined Cycle Power Plant, CCPP)中机组动态模型研究的不足,解决常用的电力系统仿真软件不提供CCPP仿真模型的问题,针对国内9F级重型CCPP机组所具有的不补燃余热锅炉、单轴型结构、滑压运行等特点,研究并建立了CCPP机组的实时数字仿真模型。首先在Matlab/Simulink环境下建立了非实时数字仿真模型,然后将其转换为C语言代码,并利用CBuilder工具将其封装为可以实时运行的仿真模型。最后,在RTDS上对模型进行了仿真测试,并与现场实测结果进行了对比验证。仿真结果表明,所建立的CCPP机组模型在计算效率和模型精确性等方面均能满足电力系统的实时仿真要求。 |

Abstract: |
At present, there is very limited research on dynamic modeling of gas-steam combined cycle power plant (CCPP) units domestically, and the commonly used power system simulation software still lack CCPP models, to build a CCPP units model based on the characteristics of the domestic 9F heavy duty CCPP units with unfired heat recovery steam generator, single shaft and sliding pressure control, a real time digital simulation model of CCPP units is established. Firstly a non-real-time digital simulation model is established in the Matlab/Simulink environment, and then the model is converted into C language code. Secondly by using CBuilder, C language code is encapsulated in a simulation model which can run in real time. Finally the model is tested on Real Time Digital Simulator (RTDS), and verified with the field test results, which demonstrates that the developed CCPP model can meet the real time simulation requirements of power system in terms of computation efficiency and model accuracy. |
