Abstract: In the present work, we focus on the study of dynamic behavior of an interconnected two-area power system and a scheme for improvement of response for the same. Here, two-area system with one non-reheat thermal units & one reheat thermal units is considered. The frequency and tie-line power deviation of two units are studied using MATLAB-SIMULINK in continuous time domain and also in ...

there are some computer programs to calculate germination related traits such as germin which have using problems. the aim of this work was to adjust germin for calculating germination related traits. seed aging effects on the seedling emergence was modeled using the optimized germin. this study was conducted based on completely randomized design in a factorial combination of five seeds aging t...

With recent findings of grass carp Ctenopharyngodon idella in tributaries of the Great Lakes, information on developmental rate and larval behavior is critical to efforts to assess the potential for establishment within the tributaries of that region. In laboratory experiments, grass carp were spawned and eggs and larvae reared at two temperature treatments, one "cold" and one "warm", and track...

Recently, thermal-aware digital circuit design in advanced technologies is great challenges to realize high-speed and robust microprocessors. In this paper, we explore temperature gradient alleviating method for arithmetic units. Aiming at alleviating temperature gradients at logical circuit design level, we try to flatten out a power density by applying delay-balancing technique for equaldelay...

Polyhydroxyalkanoates (PHAs) are biodegradable polyesters that have a wide variety of physical properties dependent on the lengths of the pendant groups of the monomer units in the polymer. PHAs composed of mostly short-chain-length (SCL) monomers are often stiff and brittle, whereas PHAs composed of mostly medium-chain-length (MCL) monomers are elastomeric in nature. SCL-MCL PHA copolymers can...

Smart Grids are result of utilizing novel technologies such as distributed energy resources, and communication technologies in power system to compensate some of its defects. Various power resources provide some benefits for operation domain however, power system operator should use a powerful methodology to manage them. Renewable resources and load add uncertainty to the problem. So, independe...

Abstract According to the Twenty-Five Key Requirements for Preventing Electric Power Production Accidents , protection of important capital and auxiliary equipment should adopt “Two Out Three” logic judgment method, signal follow whole process from sampling point input module. The principle relative independence is that number measuring points insufficient due system reasons, measures prevent d...
