Model-Based Control Design of Series Resonant Converter Based on the Discrete Time Domain Modelling Approach for DC Wind Turbine

Figure 16

Dynamic response of output current of DC wind turbine converter () when a step-up/-down disturbance is injected in system at t=1.0 .

(a) 4.0 step-up disturbance (0.01p.u) in the MVDC voltage ()

(b) 4.0 step-down disturbance (0.01p.u) in the MVDC voltage ()

(c) Step-up disturbance (0.26p.u) in the power reference signal (equivalent of current reference signal: 1.37A→1.73A)
