Oscillations in machines' rotor angle due to power system disturbances can result in power swing phenomena in the electrical networks. South Sulawesi 150 kV system in Indonesia consists of two sub systems that are connected by long transmission line. North side sub system contains big generation plants, whereas south side sub system is the load center. This condition often causes oscillation if there...
Single-phase Auto-reclosing (SPAR) is widely used on EHV/UHV transmission lines to improve power system reliability. However, reclosing on to a permanent fault can adversely affect the system stability and damage generators and other equipment connected to the line. To solve this problem, a new algorithm for improving the single-phase adaptive autoreclosure is presented in this paper. Firstly, primary...
This paper presents a brief explanation how synchronized measurement technology (SMT) and WAMPAC architecture can support state estimation and it discusses the existing correlation between each other. Additionally, it is presented a practical implementation of phasor measurement units for updating network parameter data bases to improve the performance of state estimators. The methodology presented...
