Abstract: Two-stage matrix converter has a real DC link, but does not contain large DC-link
energy storage capacitors compared with conventional PWM converters. Combined with the
advantages of two-stage matrix converter, AC-excited generation technique and vector control
scheme, the system of the doubly-fed wind power generation excited by two-stage matrix
converter was established. The two-stage matrix converter realizes rectifier and inverter control
with dual space voltage vector modulation. Based on the control models of idle-load
grid-connection and running in steady state of doubly-fed wind power generator, it makes wind
generator realize almost no impact current grid-connection and decoupling control of active
power and reactive power by application the control strategy of the stator flux linkage orientation.
The experimental results show that the two-stage matrix converter excitation doubly-fed wind
power generation system can realize soft grid, output active and reactive power can be
independent regulation.
