TL;DR: In this article, a set of generic equivalent collector system (ECS) parameters for power system studies of large wind power plants represented by single-machine equivalents are presented, intended to be used when actual collector system data are not available for calculating specific ECS parameters.
Abstract: This paper provides a set of generic equivalent collector system (ECS) parameters for power system studies of large wind power plants (WPPs) represented by single-machine equivalents. They are intended to be used when actual collector system data are not available for calculating specific ECS parameters. The accuracy that can be expected with the generic ECS is quantified for a sample of 17 actual WPPs in the range of 50-300 MW. Generic ECS parameters have shown to provide active and reactive powers at the ECS output whose accuracies are adequate for prospective or preliminary studies.

TL;DR: Pulsed laser deposition has been used to prepare two types of superionic ceramic thin films: (i) NASICON (Na superionic conductor) for a Na ion selective membrane and (ii) the mixed electronic and oxygen conductors La1−xSrxMnO3±δ (LSM) for the cathode in solid oxide fuel cells as mentioned in this paper.

TL;DR: In this article, the possibility for a privately managed hydro-power system to adapt to a projected increase in water flow in their central-Quebec watersheds by adding power generation potential was discussed.
Abstract: This paper discusses the possibility for a privately managed hydro-power system to adapt to a projected increase in water flow in their central-Quebec watersheds by adding power generation potential. Runoffs simulated by a lumped rainfall-runoff model were fed into a stochastic dynamic programming (SDP) routine to generate reservoir operating rules. These rules were optimized for maximum power generation under maximal and minimal reservoir level constraints. With these optimized rules, a power generation simulator was used to predict the amount of generated hydropower. The same steps, excluding calibration, were performed on 60 climate projections (from 23 general circulation models and 3 greenhouse gas emission scenarios) for future horizons 2036–2065 and 2071–2100. Reservoir operation rules were optimized for every climate change projection for the 3 power plants in the system. From these simulations, it was possible to determine hydropower numbers for both horizons. The same steps were performed under a modified system in which an additional turbine was added to each power plant. Results show that both the non-structural (optimizing reservoir rules) and structural (adding turbines) adaptation measures allow for increased power production, but that adapting operating rules is sufficient to reap the most of the benefits of increased water availability.

TL;DR: Similarity laws governing the internal damping of stranded cables in transverse vibrations are based on the assumption of hysteretic loss factor associated with the flexural rigidity of the cable and the assumption that this loss factor is the same for all cables of the same construction.
Abstract: Similarity laws governing the internal damping of stranded cables in transverse vibrations are based on the assumption of hysteretic loss factor associated with the flexural rigidity of the cable and the assumption that this loss factor is the same for all cables of the same construction. These laws are derived from the basic cable differential equation. The proportionality factors, the exponents of the various parameters in the laws, are obtained from the experimental results of a typical member of a family of similar cables. The same set of laws has been found to apply very well to ACSR (aluminum conductor steel reinforced) conductors having the same number of strands and fairly well to all ACSR conductors. Other families of cables, such as ACAR (aluminum conductors aluminum reinforced), steel cables, etc., could each have their own set of similarity laws, which would all look alike. >

TL;DR: In this paper, a 13m3 wood dryer coupled with a 5.6kW heat pump was used for drying hardwood wood stacks, and the drying curves, share of the final moisture content, and final quality of the dried wood stacks were determined for each drying run.
Abstract: This article presents a 13-m3 wood dryer coupled with a 5.6-kW (compressor power input) heat pump. Drying tests with hardwood species such as yellow birch and hard maple were completed in order to determine the system's energy performance. Supplementary heating to compensate for the dryer heat losses was supplied using electrical coils or steam exchangers. The heat pump running profiles and dehumidification performance in terms of volumes removed and water extraction rates, coefficients of performance, and specific moisture extraction rates were determined for two all-electrical and two hybrid drying tests. The hardwood drying curves, share of the final moisture content, and final quality of the dried wood stacks, as well as total drying energy consumption and costs, were determined for each drying run. Finally, the total energy consumption of the drying cycles using a heat pump was compared with that of a conventional drying cycle using natural gas as a single energy source.
