PP氮气管网压力控制优化设计

his paper mainly introduces the problem of nitrogen pressure control instability in CCPP during the oil and gas switching process, according to feedback and feedforward control principle, using DCS technology and CCM Studio configuration software. Through multiple experimental analysis and comparison, the nitrogen pressure control system was optimized by the feedforward feedback composite control technology, and the pressure stability control of the nitrogen was realized.It meets the operating conditions of the unit under various working conditions and ensures the safety and stability of CCPP.
