Generation projects are generally located in areas nearer to availability of inputs required for power generation such as water, coal, approach roads and having rail transport facilities. The load centers are at different locations depending its own convenience load requirement. Hence there is necessity of transmission of bulk power from generation sites to load or consumer points. Hence the utility of power transmission through EHV/UHV transmission lines. Further for transmission of bulk power from one region of country to another region also warrants establishment of Transmission lines. The

The scientific evaluation of extra-high voltage (EHV) and ultra-high voltage (UHV) hybrid transmission lines presents essential research demands for power transmission systems’ efficiency. The high-capacity transmission lines need proper electric and magnetic field (EMF) management because public concerns about environmental and health risks keep rising. The relationship between power grid lines and surrounding areas needs thorough study to fulfill health-related requirements and earn public trust in power projects.

Abstract:

The infrared thermal image detection method has unique advantages in the field of low zero value diagnosis of porcelain insulators. However, since the length of the extra–ultra-high voltage (EHV–UHV) porcelain insulator string can reach more than 10 m, it is difficult for common industrial thermal imagers/airborne lenses to clearly capture the infrared spectrum of the full string of EHV–UHV porcelain insulators. In order to solve this problem, this paper proposes a two-segment temperature curve splicing method based on weighted data fusion. The method avoids the problem of missing targets exis

Abstract: Distance protection and differential protection schemes are the two primary types of protection schemes employed in gearbox line protection today. However, industrial practice has shown that commonly used gap prevention techniques are limited in tripping speed and selectivity. The timing of the samples in each of the two relays located at the gearbox line terminals also affects the differential protection mechanism. On the other hand, pilot safety schemes using only the communication link to exchange local decision-making about fault conditions are not affected. These method include

The most accurate and standard modeling of steady-state modes of an overhead line using long line equations (LLE) with distributed parameters in hyperbolic functions is accepted. When obtaining the LLE, an assumption was made about the quadratic dependence of active power losses to the corona on voltage. Numerous measurements of active power losses to corona in overhead lines of ultra-high voltage (UHV) and processing of experimental results have established that the dependences of active power losses to corona are a function of voltage of the 4–8th degree.
