Advanced modeling and control package for power system problems

An intelligent computer aided engineering (CAE) control design software and hardware package for power system control has been developed in this project. This package encompasses advanced control technologies, software technologies and hardware technologies. It allows the whole design process to be cycled easily and efficiently, thus considerably speeding up the control system design and prototyping. The main objectives of the project consist of: (l) modeling of STATCOM (static compensator) in power system; (2) development of computer aided engineering platform; (3) design and development of digital signal processor (DSP) based controller; and (4) development and application of advanced control techniques for STATCOM. Three types of controller, namely PI-auto-tuning, fuzzy logic control (FLC) and iterative learning control (ILC) are incorporated in the platform. For the real-time control, a DSP-based hardware controller is designed and implemented. Field-site experiments were carried out on a 10 kVAr STATCOM to show the performance of the controller and results are satisfactory.
