Design of MPPT characteristic measurement and control system for wind power generation system

Abstract： In small and medium-sized permanent magnet synchronous wind turbines, the bridge rectifier + DC / DC converter topology has the advantages of simple structure. The DC / DC circuit has Boost and Buck topologies. Exploring the difference between the maximum power point tracking ( MPPT ) control performance of the two is the key to its optimal design. The measurement and control system is an important means of performance analysis. Through the overall scheme design of the system, the system parameters and indexes are confirmed. The four-leg DC / DC topology is analyzed, and the acquisition of system voltage, current, power and frequency is realized based on high-end current sampling and isolated sampling technology. The power drive and single chip microcomputer control circuit are designed. The software of MPPT climbing search method suitable for single chip microcomputer is discussed. The software design and implementation of the upper computer control system based on LabVIEW is given. The measurement and control system is built, and the MPPT and two topology measurement and control results are compared. The experimental results show that the measurement and control system has achieved the design goal.
