The present application relates to fuel cell power station control technical field, disclose a kind of multi-module fuel cell power station based on efficiency power regulation method.The method first obtains power station request power P0And the minimum output power Pmin of single fuel cell power module, according to the numerical relationship of both to determine the number of opened module and initial power is divided equally;When opening 4 modules, real-time detection and comparison each module operating efficiency, calculate the difference between the highest and lowest efficiency, if the difference exceeds the set threshold, with half of the product of the divided power and the efficiency difference as the adjustment amount, increase power to high-efficiency module, reduce power to low-efficiency module, cycle adjustment until the module efficiency difference is within the set range.The present application can avoid module running below the minimum output power, expand the power range of power station, while making the efficiency of each module consistent, reducing the decay of low-efficiency module, prolonging the overall operation life of power station, solve the problem of poor efficiency and short life caused by the existing power division method.
