摘要： 摘要：针对600MW直接空冷机组背压飞升问题，提出空冷机组背压飞升的快减负荷控制策略。通过对某600MW亚临界直接空冷机组背压保护逻辑优化，降低了由于直接空冷机组受到环境大风影响，造成空冷岛上方热空气回流，引起的机组背压飞升跳闸的风险，保证了机组在高背压恶劣环境下的安全运行。

Abstract: Abstract:The author put forward runback control strategy in order to resolve soaring back pressure of the 600MW direct air cooling unit.Back pressure protection logically system of 600MW subcritical direct aircooling unit were optimized, risks of environmental strong wind may generate hot air back flow above air cooling island and with soaring back pressure, direct aircooling unit may trip were reduced. In this way, the unit safe operation under hostile circumstances of high back pressure were ensured.

Key words: Keywords:direct air cooling unit, back pressure soaring, runback, logical optimization
