With the rapid growth of power system, it is becoming increasingly difficult to realize reach and time coordination for conventional backup protection. To cope with those problems, wide-area protection is widely researched. In this paper, a novel dynamic cooperation mechanism of wide-area protection is proposed, which can operate better than distributed and centralized systems with respect to r...

MAHAJAN, NIKHIL RAVINDRA. System Protection for Power Electronic Building Block Based DC Distribution Systems. (Under the direction of Mesut E Baran) The purpose of this research has been to develop an agent based protection and reconfiguration scheme for power electronic building block based (PEBB) DC distribution systems. One of the foremost applications would be in the new zonal DC distribut...

Abstract: The risks of alternating current (AC) corrosion and overprotection increasingly demand new criteria forcathodically protected pipelines. To assess the risk of AC corrosion, new cathodic protection (CP) criteria have beenproposed based on DC/AC current densities measurements using coupons. The monitoring system designed for thisproject was based on the instant-off method, with steel co...

Power systems are extraordinary dynamic and complicated systems with various components and tools of generation, transmission, distribution, protection and control to guarantee the nation-wide interconnected grid's daily operation and safety. This paper reviews the latest Phasor Measurement Unit (PMU) technology development and applications in power system dynamic analysis and reduced model par...

internal turn-turn faults (ttf) are the most common failures in power transformers, which could seriously reduce their life expectancy. although common protection schemes such as current-baseddifferential protection are able to detect some of the internal faults, some other minor ones (such as ttfs andshort circuit near the neutral point) cannot be detected by such schemes. likewise, these rela...

Energizing of large power transformers is considered a critical event in the operation of an electric power system. When a transformer is energized by the grid or utility, it takes very high value current known as inrush current, the typical value of this current could be ten times. This inrush causes many problems like mechanical stress on transformer & harmonics injection to generator winding...

In power system protection, the need to know the load current together with the fault level detected by a relay is important. This is due to the fact that the relay is required to isolate the equipment being protected if a fault is present and keep the breaker associated with it closed if the current level is lower than the maximum load level. This is not an issue for a radial system. This is n...

The vision of the smart grid is predicated upon pervasive use of modern digital communication techniques in today's power system. As wide area measurements and control techniques are being developed and deployed for a more resilient power system, the role of communication networks is becoming prominent. Advanced communication infrastructure provides much wider system observability and enables g...

The growing concern about wide area power system disturbances and their impact on power systems have reinforced interest in the new generation of system protection tools. Their application depends on their reliability, which, in turn, depends on the reliability of the hardware infrastructure on which they rely. In this paper, we propose a modification of a Voltage Instability predictor (VIP) [1...
