燃气—蒸汽联合循环发电技术在青海电网中的应用

Application and Practice of Gas-steam Combined Cycle Power Train Generating Technology in Qinghai Power Grid

针对燃气轮机结构、设备和热力系统及运行控制与火电机组差异大、机组自动化技术水平比较高的特点,在机组调试过程中大胆创新,改进调试工作程序和流程及调试方法,对调试工作中遇到的技术难点和问题进行认真研究分析,成功解决了燃煤机组调试中不曾出现的疑难问题。经过现场的摸索、实践,解决了高海拔地区燃机调试中的关键技术难题,为今后的燃气—蒸汽联合循环在高海拔地区的应用和实践提供了借鉴。

Aiming at the comparative difference of structure, equipment, thermodynamic system and operating control between gas turbine and thermal power units, and the character of higher automation level, the paper makes a describe on the debugging process, and analyzes the technical difficulties. Thus solves the key technical problems on high elevation areas and provides reference for the future application of gas - steam combined cycle power train on the high elevation areas.
