Repairing SLS anomalies in NZ seismic code to reduce earthquake losses

Reviewing the Impact of FACTS Devices to Reduce Losses and Voltage Profile in the Pool Market

Abstract: In this paper, a generalized Lagrangian-based algorithm (TRALM) and gravitational search algorithm (GSA) are used to solve the Optimal Load Distribution Problem (OPF) in the presence of FACTS equipment. Four TCSC, TCPST UPFC and SVC equipment’s have been tested. Modeling of FACTS equipment is based on power injection method. To optimally manage production, losses and voltage profiles,...

Izmit Earthquake on Seismic Hazards in Istanbul

We calculate the probability of strong shaking in Istanbul—an urban center of 10 million people—from the description of earthquakes on the North Anatolian fault system in the Marmara Sea during the past 500 years, and test the resulting catalog against the frequency of damage in Istanbul during the preceding millennium. Departing from current practice, we include the time-dependent effect of st...

Introduction of Air Cushion to Reduce Seismic Demand in Cylindrical Water Storage Tanks

Water storage tanks not designed explicitly for seismic loading could require retrofit. One of the common ways of retrofit include some structural change in the lateral load resisting system that could be expensive and requires the tank to be out of service for relatively long time. This paper introduces a novel method to reduce seismic demand on tank’s wall without structural intervention. Thi...
