中电江门综合能源有限公司2X60MW 级天然气分布式能源站项目是由中国中建设计集团有限公司华南分公司总承包，联合循环采用“一拖一”配置方案，单台机组由一台燃气发电机组，一台余热锅炉及一台蒸汽轮机发电机组成，以热、电、冷三联供的方式实现能源的梯级利用，为江门高新技术产业开发区发展保驾护航。采用国内首台高转速蒸汽轮机的6F.01型分布式能源站机组，蒸汽轮机额定转速达5000转/分，机组出力得到明显提高。燃气轮机燃烧温度接近1400摄氏度，配以干式低氮燃烧系统，有效减少氮氧化物排放，环保指标优于国家排放标准。该项目的DCS、DEH均采用艾默生Ovation控制系统，在艾默生、华南电力实验研究有限公司、西安热工研究院有限公司、中电江门综合能源有限公司生产技术部刘文领等及运行人员的一起协力配合下，先后数次对机组APS控制策略进行修改和实验，经过精心调试，保证了APS功能的投运，并顺利通过业主的验收。本文后续将重点介绍DEH系统APS启、停的控制方式。

The 2X60MW natural gas distributed energy station project of CLP Jiangmen comprehensive energy Co., Ltd. is generally contracted by China Construction Design Group Co., Ltd. South China branch. The combined cycle adopts the "one driven one" configuration scheme. A single unit is composed of a gas-fired generator unit, a waste heat boiler and a steam turbine generator to realize the cascade utilization of energy by means of combined supply of heat, electricity and cooling, Escort the development of Jiangmen high tech Industrial Development Zone. 6F, the first high-speed steam turbine in China, is adopted 01 distributed energy station unit, the rated speed of steam turbine reaches 5000 rpm, and the output of the unit has been significantly improved. The combustion temperature of the gas turbine is close to 1400 ° C. equipped with dry low nitrogen combustion system, it can effectively reduce the emission of nitrogen oxides, and the environmental protection index is better than the national emission standard. Emerson ovation control system is adopted for DCS and DEH of the project. With the cooperation of Emerson, South China Electric Power Experimental Research Co., Ltd., Xi'an Thermal Power Research Institute Co., Ltd., Liu Wenling of production technology department of CLP Jiangmen comprehensive energy Co., Ltd. and operators, the APS control strategy of the unit has been modified and tested for several times. After careful debugging, the operation of APS function is ensured, And successfully passed the acceptance of the owner. This paper will focus on the control mode of APS start and stop of DEH system.
