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。
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 aircooling unit may trip were reduced. In this way,the unit safe operation under hostile circumstances of high back pressure were ensured.
