The invention discloses a vanadium battery electrolyte circulation system control method. The method comprises the following steps: S1, setting a control method in a system starting stage; s2, setting a control method of a system operation stage; s3, setting a control method of a system stop stage; s4, based on the set control method of the system starting stage, the set control method of the system operation stage and the set control method of the system stopping stage, safe operation of the vanadium battery electrolyte circulating system is completed. Different control strategies are adopted in the three stages of starting, running and stopping of the circulating system, and safe running of the whole battery system is guaranteed. In the starting and stopping stages of a vanadium battery electrolyte circulating system, due to the electrical characteristics of an external pump, the flow difference in a pipeline and the liquid level difference in a tank body fluctuate greatly, so that protection logic is trigg
