PROBLEM TO BE SOLVED: To provide a condenser cooling water flow regulating device capable of stably supplying cooling water without relying upon a variation in liquid level difference in a condenser cooling device for cooling a condenser recycling turbine steam of a power generating plant. SOLUTION: This condenser cooling water flow control device comprises an intake chamber liquid level gauge 22 fitted to an intake chamber 4 arranged continuously with an intake port 1 for taking cooling water from a condenser cooling device 10 with a condenser 9 of a steam turbine, a water release tank liquid level gauge 23 fitted to a cooling water release tank for releasing cooling water after cooling the condenser, and a control device 24 controlling the opening of a pump outlet valve 7 installed at the outlet of a cooling water supply pump 5 pumping up water from the water storage tank. The liquid levels in the intake tank 4 and at the water release port 18 are measured with the intake tank liquid level gauge 22 and the water release tank liquid level gauge 23, the liquid levels are inputted into the control device 24 to calculate a liquid level difference, and the flow of condenser cooling water is regulated by controlling the opening of the pump outlet valve 7.
