Study of the double rotor double machine wind turbine generation system

Abstract

A new power system with new energy as the main body will be built. Wind power generation will become an important part of the new power system. Compared with onshore wind power, offshore wind power has become a research hotspot with the advantages of abundant wind resources, high utilization rate, close distance from power load, easy power transmission and consumption. However, with the large-scale offshore wind turbine capacity and the improvement of the proportion of wind power, its disadvantages of weak impact load resistance, weak grid friendliness, large volume and high cost are becoming increasingly prominent. In view of the above problems, this paper carries out the research on the design and modeling of double rotor double machine wind turbine generation system. The research contents include the designing the structure, analyzing the working principle, establishing the math model and proposing the control strategy. The system designed in this paper has the characteristics of strong impact load resistance, good power quality, high power grid stability and reliability, small volume, light weight and low cost.
