Final revisions and Delivery.
I this week was doing the necessary adjustments on the simulator to include the other onshore converter station and the others two lines transmission.
Was even included a different model of voltage control in order to take advantage of a power sharing between the two stations, beneficial in situations of network failures.
It were obtained the first correct results of the simulator even with a basic model of control onshore converter and without upstream network.
After meeting with the supervisor, the equations of the network were approved and in this week, the implementation of simple scheme studied in Week 5 was initiated, representing the equivalent equations of the simplified scheme in the simulation environment with the help of Matlab Simulink application.
Continuation of work developed on Week 5.
Inclusion of another Onshore converter station and two more lines, one connecting the wind farm 2 to the converter station 2 and another between the two Onshore converter stations. Therefore the next figure represents the final network.
Some work of literature was also developed during this week, and was even made an introduction to the study of direct current transmission systems.
Schema definition of multi-terminal HVDC network through the equational representation of the lines and buses. Assuming that the lines are represented by the model in pi, as in figure 1, the following equations represent the network shown in Figure 2.
Highlighting that the network under test is a Bipolar Network, so this representation is only one pole, the other is connected in parallel with connection to the same ground point.
Continuation of the literature of Week 3.
