| Resumo: | Almost all the world-wide electric power Systems, included the Brazilian one, have experienced problems in relation to the high loading levei of transmission lines, caused by the lack of investment to compensate the growing power demand. Aiming to solve this problem, it was developed, in the eighties, a technology denominated FACTS (Flexible AC Transmission Systems), which employed passive elements as resistors, reactors and capacitors in its first family. In the most recent generation equipments, these elements were substituted by modem inverters, thanks to the evolution of power electronics and, more specifically, high power semiconductor switches like GTOs. Within the FACTS devices, referred by advanced static compensators, that named STATCOM stands out, since it accomplishes the control of reactive as well as active power. This work was conceived taking into account several aspects related with this FACTS equipment such as: operational principies, mathematical modelling and computational implementation. Adding to these purposes, the results of Computer investigations with the simulation package “SABER” are presented and discussed in order to analyses the dynamic behaviour of an electric power system equipped with such compensator, when the system is submitted to some great disturbances. |
