PROBLEM TO BE SOLVED: To provide a bering cooling water system in generator sets for supplying cooling water for cooling a control compressor without use of external cooling water even when the unit bearing cooling water system of a power generation unit is stopped. SOLUTION: The bearing cooling water system 3 in generator sets includes: multiple independent unit bearing cooling water systems 1, 2 that respectively circulate cooling water for cooling the bearing sections 13, 23 of each equipment including control compressors 12, 22 for supplying control gas in multiple power generation units each equipped with a generator; communicating pipe lines 4A, 4B that connect the unit bearing cooling water systems 1, 2 of adjacent power generation units so that cooling water for either unit bearing cooling water system 1 can be supplied as cooling water for the other unit bearing cooling water system 2; and communication on-off valves 5, 6 that are placed at some midpoints in the communicating pipe lines 4A, 4B and open and close the communicating pipe lines 4A, 4B.
