This file has been generated by running an initial simulation to steady-state for an integer number of cycles of 60 Hz.

We can see that the dynamic response of the DC regulator to this sudden load variation kW to kW is satisfactory. The DC voltage is back to V within 1. We can see that the DC voltage drops to V. A drastic change in the primary current waveform can also be observed. When the pulses are blocked, the Three-Level Bridge block operation becomes similar to a three-phase diode bridge. A drastic change in the primary current waveform can also be observed. When the pulses are blocked, the Three-Level Bridge block operation becomes similar to a three-phase diode bridge.

If you modify this model, or change parameter values of power components, the initial conditions stored in the "xInit" variable will no longer be valid and Simulink will issue an error message. To regenerate the initial conditions for your modified model, follow the steps listed below:. Double click on the Breaker block and temporarily disable the breaker closing by multiplying the "Switching time s " parameter by Temporarily disable pulse blocking by multiplying the " Time s " parameter by Change the Simulation Stop Time to 0.

Note that in order to generate initial conditions coherent with the 60 Hz voltage source phase angle, the Stop Time must an integer number of 60 Hz cycles. Joel Van Sickel on 29 Jun Cancel Copy to Clipboard. Hello Neethu,. Could you confirm that this is the model you are referencing?

Is this the model you are asking about? If so, what block are you trying to modify with the above question? I tried to change the active power reference negative, by giving a negative value say -1 directly as idref instead of DC voltage regulator. But the model doesnt follow negative active power reference.

Can i know how can i modify the model so that it follows negative id ref same like it follows negative iqref. Mohsen Aleenejad on 29 Jun My understanding is that the topology is not physically able to follow the negative reference.

The load consists of two parallel resistive branches. As a rsult, the active power is always positive and Id cannot remain negative. Thank you. Can you suggest some solution to this? Mohsen Aleenejad on 30 Jun
