660MW空冷凝汽器背压的控制逻辑分析与优化

Control Logic Analysis and Optimization of 660MW Cooled Condenser Backpressure

直接空冷机组背压的控制策略在直接空冷机组稳定运行中起着关键性作用,因此凝汽器背压的控制一直以来是人们重点研究的对象。以鸳鸯湖2×660MW直接空冷机组为例,深入分析直接空冷机组凝汽器背压的影响因素,在保证安全运行的条件下,对直接空冷机组的背压控制方案进行了深入的分析并进行了控制策略的优化。

Direct Air Cooling Units backpressure control strategy in direct air cooling unit plays a key role in the stable operation. So condenser backpressure control has been the object of research which people focus. In Yuanyang- hu 2 × 660MW Direct Air Cooling Unit Case, the influencing factors of Direct Air Cooled Condenser backpressure were deeply analysed. In ensuring the safe operation conditions, the direct air cooling unit back pressure control pro- gram was carried out in-depth analysis and control strategy optimization.
