Abstract

With rapid development of capacity and high voltage withstand ability of power switching elements, shunt type static synchronous compensators (STATCOMs), which is one of the FACTS elements, can replace the roles of traditional static var compensators(SVCs) for enhancement of power system performances. Traditionally, with phase-independent control ability, delta-connected SVCs are widely employed in power industries for balance of unbalanced load and correction of load power factor. However, due to the conduction characteristics of the thyristors and passive L, C elements used in the SVC, the SVC has its natural limitation of response time, which can be enhanced. In the project, a delta-connected STATCOM with multilevel full H-bridge (FHB) inverter will be developed and implemented. First, a new control scheme employing instantaneous reactive power detection will be derived in the STATCOM for real-time load balancing and power factor correction. Then, use of the simulation program MatLab/Simulink constructs the STATCOM simulation system. Computer simulation will be performed to evaluate the effectiveness of the developed control scheme for the STATCOM. At the same time, a hardware prototype STATCOM will be scheduled and built. A multi-controller based control system employing the TMS320F28335 DSPs will be built for the STATCOM. Finally, experimental test will be made for verification.
