The invention discloses an NSGAII-based multi-objective optimization method for capacitor module component configuration in the field of capacitor module components. The method comprises the followingsteps: determining a constraint condition according to a capacity value and a quality value of a capacitor module required by a functional index by taking the lowest output voltage drop, the lowest cost and the smallest size of the capacitor module formed by each capacitor component as objectives; and establishing a multi-objective optimization model, and then solving the multi-objective optimization model based on a multi-objective genetic algorithm NSGA-II. According to the method, the NSGA-II multi-objective genetic algorithm is used for solving a problem of capacitor module component configuration, a non-inferior solution set meeting requirements is obtained, guidance is provided for application implementation, and good performance is obtained on the whole. Meanwhile, a constraint violation value method is introduced into constraint processing, feasible solutions are included in the scheme search process, some excellent approximate solutions are reserved, local optimum is not likely to happen in scheme search, more comprehensive scheme decision support can be provided, and the actual engineering design requirement is met.

technical field [0001] The invention relates to the field of multi-objective optimization for configuration of capacitor module components, in particular to an NSGA-II-based multi-objective optimization method for configuration of capacitor module components. Background technique [0002] With the rapid development of power electronic converter technology, the pulse load represented by phased array radar has become one of the most widely used loads in weapons and equipment. The typical characteristics of this type of load are low average power, high peak value, short cycle and large impact. In order to ensure the stable, reliable and economical power supply of the radar power supply system, the commonly used energy storage capacitor module quickly responds to the peak power demand of the pulse load and stabilizes the power fluctuation of the system, which is an important part of the design of the radar power supply system.
