| Summary: | 博士 === 國立中正大學 === 電機工程所 === 97 === Power quality problems are often produced by industrial systems with bulk nonlinear loads, which in turn threaten to power system networks. In such situation, the supply quality provided by electric utilities may be affected and also impacts their customers. It is thus necessary to search new simulation techniques for investigating these problems. Traditional off-line simulation is commonly seen technique for researchers and engineers performing power engineering studies. However, it is now insufficient to simulate a complicated power system due to the many physical limitations.
This dissertation integrates PC hardware and software to develop a PC-cluster based real-time simulator on MATLAB/SIMULINK environment. Various studied systems consist of AC electric arc furnace, DC and AC motor drives, and power quality mitigation devices such as static var compensators and passive harmonic filters are under test; meanwhile, the test results obtained by off-line simulations with variable-step solver and actual filed measurements are used to verify the performance of the simulator. It is found that with the power of parallel computing and novel solution techniques provided by the simulator to perform power quality studies, the real-time simulation achieves satisfactory solution accuracy within much less execution time while in comparing with traditional off-line simulations.
