Using dSPACE in the Shunt Static Compensators Control
Journal Title: ANALELE UNIVERSITATII DIN CRAIOVA - Seria Inginerie electrica - Year 2013, Vol 37, Issue 37
Abstract
This paper presents the design and implementation of an active filtering system based on a DSP acquisition board. This approach has the advantage of versatility regarding the command and control section of the filtering system, for a given power topology. The power section contains the typically components of an active filter, such as the three phase voltage source inverter, the first order interface filter, and the compensating capacitor. Thus, the rated power of the filtering system is imposed by the compensating capacitor value, and by the power transistors rated current and voltage. On the other hand, the command and control section of the filter is limited only by the system transducers. Therefore, the system can have any compensating current computation algorithm, which can also be changed at any moment, and, at the same time, the system can have any topology for the current and voltage regulating loops. Although the active compensator can be controlled using a physical control panel, the easiest and most versatile way is to use a virtual control panel, which can be built using the acquisition board specific software. The disadvantage of this system is that the industrial computer which contains the acquisition board must be located in the close vicinity of the inverter.
