Air-cored machines offer benefits in terms the elimination of magnetic attraction forces between stator and rotor. With no iron in the stator there is not a good thermal conduction path for heat generated by Joule losses in the stator winding. Results from both models and experimental tests are provided in this paper to investigate different methods of cooling air-cored windings, including natural air-cooling, direct liquid cooling, and the use of heat pipes.

Performance optimization of induction motors during voltage-controlled soft starting Zenginobuz, G; Cadirci, I; Ermiş, Muammer; Barlak, C (Institute of Electrical and Electronics Engineers (IEEE), 2004-06-01) This paper deals with the performance optimization of medium/high-power induction motors during soft starting by eliminating the supply frequency torque pulsations, and by keeping the line current constant at the preset value. Starting torque pulsations are eliminated by triggering back-to-back-connected thyristors at proper points on the first supply voltage cycle. Line current during starting can be kept constant at any preset value by a simple strategy composed of successive cosinusoidal and constant fun...
Promoting the Investment on IPPs for Optimal Grid Planning TOR, Osman Bulent; Güven, Ali Nezih; Shahidehpour, Mohammad (Institute of Electrical and Electronics Engineers (IEEE), 2010-08-01) This paper presents a transmission expansion planning (TEP) model which coordinates investment decisions in monopolistic transmission and decentralized generator sectors. The proposed planning approach gauges transmission congestion and security constraints with respect to transmission investments while promoting investments on independent power produces (IPPs) through incentive payments. The paper includes discussions on incentive mechanisms and prioritization among qualified IPPs for several planning scen...
Determination of Rheological Models for Drilling Fluids (A Statistical Approach) Kök, Mustafa Verşan (Informa UK Limited, 2004-01-16) A rheological model conventionally characterizes non-Newtonian drilling fluids. Parameters of the rheological models are estimated by explicitly solving the required number of equations simultaneously. Rheological models are stochastic and this study considers only the deterministic part of the model. Observed data is accepted as arising from randomness due to the system. A nonlinear least squares method is applied to readings of 6 standard Fann viscometer speeds in order to estimate the models' parameters....
Finding optimal schedules in a home energy management system Merdanoglu, Hakan; Yakici, Ertan; Dogan, O. Tufan; Duran, Serhan; Karatas, Mumtaz (Elsevier BV, 2020-05-01) In this study, we model and solve the scheduling problem embedded in a home energy management system (HEMS), which enables users to overcome the major obstacles in implementing demand response programs. The problem aims to find the minimum energy cost while taking into account the time-varying prices, generation from renewable sources, usage demands for each appliance in household, battery storage capacity and grid constraints. Due to the uncertainties in supply, demand and electricity price, a stochastic o...
Enhanced capacitive behaviour of graphene based electrochemical double layer capacitors by etheric substitution on ionic liquids Siyahjani, Shirin; Oner, Saliha; Diker, Halide; GÜLTEKİN, BURAK; Varlikli, Canan (Elsevier BV, 2020-08-01) In this study, we report the effect of etheric substituents in imidazolium and ammonium based ionic liquids (IL) on the performance of electrochemical double layer capacitors (EDLC) consisted of gel polymer electrolyte (GPE) and reduced graphene oxide (RGO) electrode. GPEs contain poly (vinylidene fluoride-hexafluompropylene) (PVDF-HFP) and the ILs. Ammonium and imidazolium based ionic liquids (ILs) differ by their length of etheric groups and etheric group contents, respectively. According to the cyclic vo...
