The circuit of DSTATCOM is analyzed. The dynamic model of DSTATCOM based on three-level voltage inverter is established by way of lead-in switch function. Control method of DSTATCOM is focal point of ...this research. The dissertation determines the detection means based on instantaneous reactive power. PWM control by tracking the current technology achieve to direct control. The simulating results prove the DSTATCOM put forward in the dissertation can realize dynamic var compensation effectively.
The approach to the millimeter wave propagation loss by moment method is presented in this paper. Two terrains are calculated as examples by the method presented and compared with the results by the ...ray tracing method for open area, the technique of uniform theory of diffraction for the shadow area, respectively. Comparison results agree with each other and ensures the suitability of moment method approach to practical millimeter wave prediction
