Development of an advanced transmission line fault location system. II. Algorithm development and simulation

摘要

For pt.I see ibid., vol.7, no.4, p.1963-71 (1992). The authors describe the solution techniques, system modeling considerations, and simulation studies performed as a part of the development of an advanced transmission line fault location system intended for use on the New York Power Authority's system. The Power Authority's Moses-Adirondack 230 kV lines were selected as a testbed for the study. A reduced model of the transmission system around the Moses-Adirondack lines was developed, and a number of electromagnetic transients program (EMTP) cases were run to establish simulated voltage and current information as fed to the fault location system. Sensitivity studies were performed to investigate the impact of various system models, hardware features, and system conditions on fault location accuracy.
