| Research Abstract |
This research aims to develop power system analyzers for stabilization control of electric power systems with dc transmissions. In the research project term 2003, we obtained the following results.
1.Development and evaluation of generator models in power system analyzers: We modeled synchronous generators via block diagrams in MATLAB/Simulink. In particular we discussed transient dynamics of a single generator-infinite bus system, which is represented with our generator models, based on dynamical system theory. It was thus concluded that dynamical system theory is applicable to evaluate experimental results of power system analyzers.
2.Evaluation of analog ac transmission line models: We evaluated physical quantities of reactors that correspond to ac transmission line models in power system analyzers. Hence we have finished the development of several elements for power system analyzers.
3.Development and evaluation of hybrid-type power system analyzers: We combined generator models and ac line models with ac/dc boards, current transducers and power amplifiers. As a result, we developed a new hybrid-type power system analyzers. In addition the simulator was evaluated with several experimental tests.
4.Analytical studies on transient stability in ac/dc power systems: We derived an analytical criterion for transient stability boundaries, and clarified constrained dynamics of ac/dc systems taking the power relation between the ac and dc transmissions into account.
