thesis on statcom

is modeled by a voltage source connected to the system through a coupling transformer. One of the consequences of such a stressed system is the threat of losing stability following a disturbance. This report presents the improvement of transient stability of a multi-machine power system with a statcom. An accurate model of the converter is required to study these interactions. University dissertation from Chalmers University of Technology. Transient stability improvement is essential from the view point of maintaining system security that is the incidence of a fault should not lead to tripping of generating unit due to loss of synchronism.

Read more, university dissertation from Stockholm : KTH. Abstract : In the last decade, particular attention has been paid to the use of Modular Multilevel Converters (MMC) for grid applications. The transient stability improvement of the multi-machine power system at different fault ondition is investigated in this work. Static synchronous compensator is widely used in power system to control power by injecting appropriate reactive power into the system. Abstract : Cascaded H-bridge (CHB) converters are today considered the industrial standard for statcom applications, mainly due to their small footprint, high achievable voltage levels, modularity and reduced losses. Statcom has the capability of improving stability and dampin by dynamically controlling its reactive power output. Repository Staff Only: item control page). Abstract : The interaction of an hvdc converter with the connected power system is of complex nature. The use of analytical small-signal converter models provides useful insight and understanding of the interaction of the hvdc system and the connected system components. Sahu, Laxmidhar (2011 modeling of statcom and SVC for Power System Steady State Operation and Enhancement of Transient Stability of a Multi Machine Power System by statcom. Flexible ac transmission system (facts) devices are found to be every effective in stressing a transmission network for better utilization of its existing facilities without sacrificing the desired stability margin. Flexible AC Transmission System (facts) controllers, such as Static Synchronous Compensator (statcom) and Static VAR Compensator (SVC employ the latest technology of power electronic switching devices in electric power transmission systems to control voltage and power flow, and play an important role as a stability.
