| Summary: | 碩士 === 國立臺灣科技大學 === 自動化及控制研究所 === 103 === With the rise of environmental awareness, many countries pay more attention on energy resources, especially for electricity, because it is already indispensable in the high-tech society. Therefore, it is the most basic policy to effectively provide stable power to the load side. This thesis adopts the most popular device, called a static synchronous compensator (STACOM), to obtain the reactive compensation due to the power loss in the electrical system.
Since a STATCOM is a nonlinear system, one selects three commonly used control theories, the sliding mode control, the backstepping control, and the T-S fuzzy control in the numerous nonlinear control theories, which are applied to a STACOM. The software MATLAB is utilized to simulate the controlled STACOM. In this thesis, the three control laws are verified by the STACOM application. Besides, the simulation results are compared to each other in order to show the control performances. Furthermore, the reactive power compensations in the stable operation can be confirmed.
