Numerical Simulation of Electric Power Transmission and Distribution Equipment
Hajime Urai, Dr. Eng. Takahide Matsuo Hiroaki Hashimoto Tatsuro Kato, Dr. Eng. OVERVIEW: The market for electric power transmission systems is expected to grow strongly, driven by growing demand for electric power in emerging economies and the adoption of renewable energy. Transformers, circuit breakers, and switchgear are important components of these electric power transmission systems. The e...
متن کاملEquipment repaired is equipment gained
According to WHO, at any one time, around 50 per cent of medical equipment in lowand middle-income countries cannot be used because of lack of maintenance or spare parts.1 We have found that unwillingness or inability to repair equipment and put it back in use is also a major cause. New equipment is made available by different international non-government organisations (INGOs) competing with on...
متن کاملRisk-based Maintenance Allocation and Scheduling for Bulk Electric Power Transmission System Equipment
This paper describes a new maintenance selection and scheduling approach for bulk transmission equipment that is based on the cumulative long-term risk caused by each piece of equipment. This approach not only accounts for equipment failure probability and equipment damage, as do most state of the art reliability centered maintenance (RCM) approaches, but it also accounts for the outage consequ...
متن کاملFeature Extraction and Classification of Electric Power Equipment Images Based on Corner Invariant Moments
Feature extraction and accurate classification of electric power equipment, help to improve the automation and intelligent level of power system management. Aiming at the problems that applying Hu invariant moments to extract image feature computes large and applying corner vector to match has too dimensions, this paper presented Harris corner invariant moments algorithm. This algorithm only ca...
متن کاملThe influence of home nonlinear electric equipment operating modes on power quality
The proliferation of nonlinear electronic loads is increasing day by day, and it can anticipate an influx of newer technologies in this domain in the future. This article focuses on the impacts of various home nonlinear electric equipment on the power quality of electrical distribution system. It was studied the influence of operating mode on the harmonic pollution generated by nonlinear home a...
