Solar source is used as a kind of abroad no pollution for its particular, the substitute of a kind of future the normal regulation energy of the future. The solar chimney power generation technology, a cutting-edge technology in solar utilization, has importance to fossil energy substitution, environment improvement and ecosystem reconstruction. First introduced the working principle of the solar chimney power generation technology are presented, as well as its RD and application both at home and abroad ,And design the inverter of Solar Chimney Power generation, presents a mathematical model of Three-phase Voltage- type Inerter and realizes it in SIMULINK Toolbox of MATLAB ,which can be used in the simulation of control system involving Three-phase Voltage-type Inerter ,and utilize Hysteresis comparison to control the There-phase Voltage-type Inerter of Solar Chimney Power generation. Draw the conclusion that the narrower width of the flux hysteresis band influence tracking results better.
