The rapid increase in the demand for electricity necessitates the power quality improvement for achieving better reliability in smart grids. Wireless Sensor Networks (WSN) is the proven technology for reliable monitoring. This paper proposes a system model for the development and implementation of WSN based communication system for the monitoring of distributed generation, loads and transmissio...

Utilities invest signi cant time and nances into substation maintenance in order to anticipate failures or accelerated aging in power equipment. Current practices include regular insulation condition tests for switching devices, reactors, power transformers, and so on. Many of the indicators of equipment condition are imprecise, unreliable and costly to obtain on a regular basis. To achieve use...

<span lang="EN-US">Twelve-pulse rectification system had been widely integrated in today’s DC traction power sub-station (DC-TPSS). This configuration successfully mitigated low order harmonic distortion. As some research findings confirmed that the dc voltage and current ripple factors may further minimize by increasing number of pulses to 18, 24, or 36. paper presented a simulation stud...

Several recent studies have provided evidence that individual lighting control results in occupant satisfaction benefits. As part of a larger series of pilot studies, we examined the use of individual controls under various lighting power constraints. The studies took place in a mock-up open-plan office space, in which participants spent around two hours doing typical office tasks and answering...

IEC61850 communication standard for digital substation automation creates a new way to think about conventional protection scheme and configuration of substation. The presence of communication link in process bus makes a revolutionary change for future digital substation. This paper discusses briefly about process bus architecture and presents a new approach of thinking in busbar structure to m...
