J. Stellenbosch University. Faculty of Engineering. Dept. of Electrical & Electronic Engineering. System identification Electric power systems Dissertations -- Engineering Thesis (M. Ing.) -- University of Stellenbosch, 1997. This thesis describes the development and testing of a pseudo-random binary sequence (p.r.b.s.) source for use as a means of excitation in system identification experiments involving power system equipment. At any instant, a p.r.b.s. signal can only assume one of two signal levels. Therefore, a p.r.b.s. can be amplified by power electronic switching elements to excite power system apparatus at high power levels. Existing topologies for the generation of such perturbation signals have a number of inherent disadvantages, which resulted in the investigation of, and the development of a new topology. A high-speed programmable p.r.b.. signal generator was implemented using programmable logic. The p.r.b.s. signal generator is used to control the current -flow direction of a bi-directional current source. This source, which consist of a current controller as well as four switching elements in an H-bridge topology, is then used to supply excitation to power system apparatus. The perturbation source was used to estimate the frequency response of a 16kVA, 22kV/220V distribution transformer. The frequency response measurements, obtained by using the p.r.b.s. source, are compared to measurements which used a sine-source and linear power amplifier as excitation means. A very good correlation between the two sets of measurements was obtained. In addition, the in situ capabilities of the perturbation source are demonstrated by a number of measurements.
