| Abstract |
A first class generator IED require high reliability and speed. Since loss of excitation and power swing of a generator commonly use impedance trajectory-based protection techniques, accurate identification is required to prevent malfunction or non-operation. In this paper, as part of the pioneering application of intelligent IEDs, we aim to analyze and identify loss of excitation and power swing simulations. First, we introduce a first class generator IED and then summarize loss of excitation and power swing. Based on the correction report and PSS/E data for the generator system of the Chilbo hydroelectric power plant, the generator control system and protection IED are designed using PSCAD. Based on the correction report and PSS/E data for the generator system of a Chilbo hydro power plant, the generator control system and loss of excitation IED are designed using PSCAD. After verifying the adequacy of the model through steady-state simulation, we intend to identify loss of excitation and power swing phenomenon based on the impedance through 13 simulations performed while varying various conditions of loss of excitation and power swing. |
