The invention discloses a water supply pump frequency-variable control method and system. By controlling a water pump connected with a power supply output end of a frequency converter to conduct normal water supply and conduct increase, decrease, dormancy and dormancy awakening control on the water pump in different judgment processes through the frequency converter when a received running command is effective, the water pump can be controlled without the cooperation with an additional water pump controller, and the problems that in the prior art, due to the fact that the water supply function can be achieved by using the frequency converter and the additional water pump controller in cooperation, cost and failure maintenance points are increased are solved.
