Development and Hardware Verification of New Control Schemes for Multi-Stage Statcom

Since 1970, static var compensators (SVCs) have been widely employed in power industry for enhancement of system performance. Recently, due to rapid development of high power switching elements such as IGBTs and IGCTs, static synchronous compensators (STATCOMs) have been recognized as next-generation compensator for enhancement of power system performance. The development and application of a new STATCOM for enhancement of power system performances will be explored in this two-year project. In the first year of the project, new control schemes will be developed for the STATCOM to enhance the response time and controlling accuracy of the STATCOM. Then, suitable simulation program such as MATLAB/Simulink or EMTPRv will be evaluated and employed for constructing the simulation system of the STATCOM. Computer simulation will be made to evaluate the effectiveness of the developed STATCOM. At the same time, a hardware prototype STATCOM will be scheduled and built. In the second year of the project, a transient network analyzer (TNA)-based test system will be built. The hardware prototype STATCOM will be completed by using multi-DSP based controller and multilevel cascade H-bridge inverter. Finally, experimental test will be made for verification.
