The invention provides a water turbine speed regulation system and method, and the system comprises a water turbine speed regulator which comprises a first control signal generation module, a second control signal generation module and a guide vane switch control module; the first control signal generation module and the second control signal generation module are both used for generating hydraulic control signals of water turbine guide vanes and sending the hydraulic control signals to the guide vane switch control module. And the guide vane switch control module is used for receiving the hydraulic control signal and controlling a switch of a guide vane of the water turbine based on the hydraulic control signal, so that the speed regulation of the water turbine is realized. According to the technical scheme, the parallel redundancy mode is adopted, logic is simple, operation is reliable, fault arrangement and distinguishing are convenient, meanwhile, the fault rate of the water turbine governor is reduced, t
