fault location in power distribution networks using matching algorithm

چکیده رساله/پایان نامه : تاکنون روش‏های متعددی در ارتباط با مکان یابی خطا در شبکه انتقال ارائه شده است. استفاده مستقیم از این روش‏ها در شبکه توزیع به دلایلی همچون وجود انشعاب‏های متعدد، غیر یکنواختی فیدرها (خطوط کابلی، خطوط هوایی، سطح مقطع متفاوت انشعاب ها و تنه اصلی فیدر)، نامتعادلی (عدم جابجا شدگی خطوط، بارهای تک‏فاز و سه فاز)، ثابت نبودن بار و اندازه گیری مقادیر ولتاژ و جریان فقط در ابتدای...

Optimum Power Loss Analysis of Radial Magnetic Bearing using Multi-Objective Genetic Algorithm

Optimum Power Loss Analysis of Radial Magnetic Bearing using Multi-Objective Genetic Algorithm

In this paper, weight optimization of radial magnetic bearing (RMB) for varying poles has been carried out using multiobjective genetic algorithms (MOGAs). The total weight of RMB and copper loss has been selected as the minimization type objective function. The maximum space available, saturation flux density, the maximum current densities that can be supplied in the coil and the load to be li...

Eye Location Using Genetic Algorithm

While there are many eye location methods our technique is the first to approach this location task using navigational routines and to automate the derivation of such routines using learning and evolution rather than manually handcrafting them. The adaptive eye location approach seeks first where salient things are and then what their identity is. Specifically, eye location involves (i) the der...

Modelling of Hydrodynamic Journal Bearing in Spatial Multibody Systems

The model of a three dimensional journal bearing with hydrodynamic lubrication is herein presented. This model is suitable for embodiment into the equations of spatial multibody systems. Both rotational and squeeze effects together with tilting effect have been taken into account. Moreover a simplified model of friction has been also reported. The proposed methodology has been applied to an exa...
