Abstract The traditional risk assessment methods do not adequately consider the specific operating environment and characteristics of a power transmission line. Therefore, new method considering information comprehensive conditions is proposed in this paper. First, model designed via statistical based on preceding failures defects Then, quantization processes state parameters components line ar...

With the expansion of the power grid, transmission lines across forests are increasing. Once forest fire occurs, it could threaten the transmission lines around or even cause them trip out. Therefore, studying the spread of forest fire is important. This paper presents a method based on Rothermel model and Huygens principle to analyze forest fire spread trend surrounding transmission line. Firs...

Electric power consumption, has been increasing uninterruptedly, being this increase specially accelerated in the last years. New power generators are been built, the installed power increases each year, thus it is necessary a way to transmit the bulk energy. Nowadays electric lines are saturated, they are reaching critical values of ampacity and sag. Therefore building new lines is necessary t...

The reliability of the power plants and transmission lines in the electricity industry is crucial for meeting demand. Consequently, timely maintenance plays a major role reducing breakdowns and avoiding expensive production shutdowns. By now, the literature contains a sound body of work focused on improving decision making in generation unit and transmission line maintenance scheduling. The pur...

Accurate analog models of power system components are required in order to realize an analog computation engine for power systems. Analog computation is an area of continued interest. Among the advantages over traditional digital methods are physically realizable solutions and faster computation times. This paper focuses on the design, simulation, and hardware verification of a static transmiss...

The physical infrastructure of the power systems, including the high-voltage transmission towers and lines as well as the poles and wires for power distribution at a lower voltage level, is critical for the resilience of the community to avoid power outages under the extreme weather related loads. In the current engineering practices, single circuit lattice steel towers linked by transmission l...

This article presents a phased array antenna employing MEMS phase shifter. The proposed phased array antenna consists of eight square patch antennas operating at 10.4 GHz with a bandwidth of 400 MHz. Feed line for each patch passes through a MEMS phase shifter realized by a series of bridges above the transmission line. The distance between the bridge and the transmission line underneath it is ...
