global results on some nonlinear partial differential equations for direct and inverse problems
در این رساله به بررسی رفتار جواب های رده ای از معادلات دیفرانسیل با مشتقات جزیی در دامنه های کراندار می پردازیم . این معادلات به فرم نیم-خطی و غیر خطی برای مسایل مستقیم و معکوس مورد مطالعه قرار می گیرند . به ویژه، تاثیر شرایط مختلف فیزیکی را در مساله، نظیر وجود موانع و منابع، پراکندگی و چسبندگی در معادلات موج و گرما بررسی می کنیم و به دنبال شرایطی می گردیم که متضمن وجود سراسری یا عدم وجود سراسر...
A New Multiterminal Fault Location Algorithm Embedded in Line Current Differential Relays
Accurate fault location on transmission lines becomes increasingly beneficial by reducing outage times and allowing faster restoration of scarce power system assets back into service. Having natural access to synchronized remote current data, line current differential protection schemes can incorporate multiterminal fault location algorithms, allowing for more accurate fault location compared w...
متن کاملTutorial on Operating Characteristics of Microprocessor-Based Multiterminal Line Current Differential Relays
Line current differential (87L) protection schemes face extra challenges compared with other forms of differential protection, in addition to the traditional requirements of sensitivity, speed, and immunity to current transformer saturation. Some of these challenges include data communication, alignment, and security; line charging current; and limited communications bandwidth. To address these...
متن کاملCurrent Directional Protection of Series Compensated Line Using Intelligent Classifier
Current inversion condition leads to incorrect operation of current based directional relay in power system with series compensated device. Application of the intelligent system for fault direction classification has been suggested in this paper. A new current directional protection scheme based on intelligent classifier is proposed for the series compensated line. The proposed classifier uses ...
متن کاملA Centralised Interlocking System for Low-density Line Signalling with a Predictive Monitoring System
The methods adopted to provide cost effective signalling systems for the low-density lines have evolved over many years. In Japan, a typical conventional signalling system for single lines consists of three kind of equipment: centralised traffic control (CTC) equipment at the control centre and each station where an interlocking equipment is also located with a single line signalling equipment....
