We verified that a large selective breaking capacity could be ensured without using high-performance breakers by conducting breaking tests as a distribution board rather than making the selection based on the catalog specifications of the breaker manufacturer when selecting a breaker for distribution boards in data centers.
This paper presents a real-time monitoring system for PV power plants based on a microcontroller Atmega328P-PU. The proposed system, whose performances can be relatively close to those achieved with commercial monitoring systems, is simple, low-cost and open source technology-based. In addition, a user interface, capable to communicate through a wireless network by using a standard communication protocol...
Demand for reliable, efficient mobile network services is increasing, as customers seek for more value-added services (VAS) from telecom operators. However, many operators still suffer from network outages as they do not have solutions in place that will detect and alert them of a problem even before it escalates. Network outages can be prevented through a comprehensive, intelligent monitoring system...
Site infrastructure sharing is the trend of future base station construction. Telecom infrastructure operators require for smooth upgrading and low TCO when sharing sites power supply, spaces and operation management. This paper introduces a new integrated hybrid power supply system suitable for the site sharing requirements. It perfectly combines many functions together, such as energy generation,...
Smart grid encompasses a variety of tools, techniques and technologies that will allow energy suppliers to more accurately measure electricity flows and remotely control each point of the transmission and distribution network using two way digital technology. In this paper, determine the optimal level of automation in distribution networks with local remote control switches and VIT switches automation...
The European Commission is supporting many projects in the field of energy saving, with the aim to improve user behavior and to help Europe to meet emission targets. In October 2012, the European Union adopted the Energy Efficiency Directive with the aim to reduce the primary energy consumption by 20% by 2020. One key point in the reduction of energy consumption energy is the awareness of final users...
