Abstract

Nowadays the use of renewable energies is increasing at a high rate, but there are limitations related to the low quality of the power sent to the utility. That is the reason why new control systems have been developed.

Due to the difficulty of having adequate equipment to implement the different control systems [1] they have been simulated, but taking into account the data acquisition times.

The paper considers the delay time in the switching status due to the data sampling and calculation of the parameters required for the control. The calculations used to obtain the phasors required to calculate the optimal switching and the switching time are shown.

In order to obtain the results, the starting point is a predictive vector control, described in [2], where the calculation times have been applied for sampling frequencies of 100kHz and 200kHz, comparing the results with the case of having a infinite sampling frequency.
