碩士 === 國立臺灣科技大學 === 電機工程技術研究所 === 86 === In this thesis, first of all, a friendly graphic user interface wasdeveloped for a generalized distribution analysis program, GDAS inan object-oriented language, Microsoft Visual C++. This phaseprovides an efficient and integrated environment for the complicated distribution system simulations. The improved GDAS program is now able to simulate a large-scale distribution system under the Microsoft Window 95 operating system in a common personalcomputer. Moreover, the integrated models of distribution transformers and their loads were successively implemented into the GDAS to overcome the difficult of convergence of a three-phase power flow due toasymmetrical distribution transformers. The way to solve the phasevoltages of secondary nodes of distribution transformers, that are excluded when the integrated models are applied, were proposed as well. Besides, to reduce the complexity of analysis of distribution feeders, the simplified three-phase models of feeders with single- and double- feeding ends were implemented into the GDAS, making the GDAS suitable for being applied in a distribution systemplanning tool or a modern distribution management system. Finally, the SVC (static var compensator) models for three phase power flow analysis were proposed and equipped into the GDAS, making the GDAS be able to analyze a distribution system with various types of SVC. The effects of the SVC on the distribution system can therefore be realized via the proposed models.
