摘要
数字式电液调节系统(DEH)是控制汽轮机运行的核心,其负荷调节系统控制性能的优劣直接影响整个机组的正常运行。在建立机组及DEH系统仿真模型的基础上,分析了DEH系统的基本结构和功能,整定了负荷串级控制系统的调节器参数,优化了反馈回路投切与阀门控制方式切换的控制算法。为现场控制系统的优化运行提供了参考依据,可以进一步提高供电品质,保证运行的安全性和经济性。
Digital electro-hydraulic control system (DEH) is the core of turbine control system, then the performance of load control system determines whether the unit can run better. Based on the building of the simulation model of unit and DEH, this paper analyzes the structure and function of DEH. And the control arithmetic of feedback loop switch and valve control mode switch is optimized by adjusting the regulator parameters of load control system. It provides the reference for the optimizing running of actual control system, improves the quality of electric power, and assures the safety and economy of running.
