Control Structures for VSC-based FACTS Devices under Normal and Faulted AC-systems | Posted on:2015-02-23 | Degree:Ph.D | Type:Thesis | University:North Carolina State University | Candidate:Babaei, Saman | Full Text:PDF | GTID:2472390017496612 | Subject:Engineering | Abstract/Summary: | | This thesis is concerned with improving the Flexible AC Transmission Systems (FACTS) devices performance under the normal and fault AC-system conditions by proposing new control structures and also converter topologies. The combination of the increasing electricity demand and restrictions in expanding the power system infrastructures has urged the utility owners to deploy the utility-scaled power electronics in the power system. Basically, FACTS is referred to the application of the power electronics in the power systems. Voltage Source Converter (VSC) is the preferred building block of the FACTS devices and many other utility-scale power electronics applications. Despite of advances in the semiconductor technology and ultra-fast microprocessor based controllers, there are still many issues to address and room to improve[25]. An attempt is made in this thesis to address these important issues of the VSC-based FACTS devices and provide solutions to improve them. | Keywords/Search Tags: | Vsc-based FACTS devices, Control structures, Electronics | | Related items |
