The problems appeared in commission debugging of the air-cooled island systems for two 600 MW air-cooled units of Guodian Longshan Power Generation Co Ltd,such as undue fast vacuum drop in air-cooled island during start-up of said units after their shutdown in winter, the rapid rise of back-pressure in said air-cooled isrand due to full-load operation of all cooling air fans and air-leakage in the steam seal system, etc. , have been analysed, and corresponding preventive measures a-dopted for above-mentioned problems in the commission debugging process being given. Regarding to a part of problems, which hadn't been solved in debugging, some concrete recommendations have been put forward.
