| Abstract: | The elementary structure and operation principle of the VSC are introduced. Detailed analysis of the PWM control principle and the steady-state mathematical model. And a steady-state controller design scheme based on the PID control principle is also proposed, Realized the regulation of active and reactive power. Digital simulation based on PSCAD/EMTDC shows that the designed controller has good control performance,the simulation results show that the method have good control ability,quick response to breakdown and good stability. |
