Renewable energy systems are of importance as being modular, nature-friendly and domestic. Among the renewable energy systems, a great deal of research has been conducted especially on photovoltaic, wind energy and fuel cell in the recent years. One of the hybrid renewable energy systems consisting of 5 kWp photovoltaic panels, 800 Wp wind turbines and 2.4 kWp fuel cell modules was installed at Clean Energy House (CEH), Pamukkale University in Denizli, Turkey. To protect this laboratory, a "Lightning Protection System" was installed at the CEH. In this study, design and installation processes of a lightning protection system for the hybrid renewable energy system at the CEH are considered.

Kinetic simulations of X-B and O-X-B mode conversion and its deterioration at high input power

Spherical tokamak plasmas are typically overdense and thus inaccessible to externally-injected microwaves in the electron cyclotron range. The electrostatic electron Bernstein wave (EBW), however, provides a method to access the plasma core for heating and diagnostic purposes. Understanding the details of the coupling process to electromagnetic waves is thus important both for the interpretation of microwave diagnostic data and for assessing the feasibility of EBW heating and current drive. While the coupling is reasonably well-understood in the linear regime, nonlinear physics arising from high input power has not been previously quantified. To tackle this problem, we have performed one- and two-dimensional fully kinetic particle-in-cell simulations of the two possible coupling mechanisms, namely X-B and O-X-B mode conversion. We find that the ion dynamics has a profound effect on the field structure in the nonlinear regime, as high amplitude short-scale oscillations of the longitudinal electric field are excited in the region below the high-density cut-off prior to the arrival of the EBW. We identify this effect as the instability of the X wave with respect to resonant scattering into an EBW and a lower-hybrid wave. We calculate the instability rate analytically and find this basic theory to be in reasonable agreement with our simulation results

Seismic response mitigation of elevated tanks by HDRB and FPS isolation systems

The aim of the paper is to evaluate the effectiveness of two isolation systems for the seismic protection of elevated steel storage tanks: High Damping Rubber Bearings (HDRB) and Friction Pendulum (FPS) isolators. As a case study, an elevated tank which collapsed during the Kocaeli Earthquake in 1999 at Habas Pharmaceutics plant in Turkey has been studied. A time-history analysis is conducted using lumped mass model to demonstrate the high base shear demand and inevitable collapse of support columns due to the insufficient shear strength. A proper design of HDRB and FPS isolator and a complete non-linear analysis of the isolated tanks prove the high effectiveness of both isolation systems for reducing the response of the tank. Results revealed that the tank with the FPS provides better performance compared to HDRB in terms of the isolation displacement convective base shear demands
