RAMIREZ Ingeniería IGBT StatCom PV curves Voltage stability In this paper the power system voltage stability problem is analyzed with active power-voltage (PV) curves, as a voltage compensator is introduced. The PV curves' shape has been a subject of great concern, especially when voltage compensators are incorporated. Nevertheless, when such devices are taken into account, ordinarily the power electronic devices' commutation it is not considered in detail. This paper proposes a shunt connected voltage compensator model that gives careful consideration to commutation dynamics. Through load variations, simulations are carried out for building the PV curves. Additionally, the field over-current protection in generators is taken into account in order to evaluate its impact on the aforementioned curves. A single-phase equivalent shunt compensator, and the proposed model, is simulated in a small power system. Results are exhibited, which show particularities that arise due to the proposed model. 2011 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49622401015 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.168 Vol.78 |
