The paper discusses substation IED data integration and its importance for implementation of automated analysis solutions. Recorded data collected from various substation IEDs is stored into a substation data mart that utilizes standardized file formats and a database interface. The data mart provides a foundation for multiple uses of substation data. Utilities are faced with a challenge of how...

After briefly analyzing the structure of a photovoltaic power substation monitoring system, a positioning system roadway based on blue tooth was put forward to connect with already existing communication and monitoring networks. A separate monitoring system for the environment is integrated with the former comprehensive automation system to create a unique system. It is a new step of substation...

This paper describes how the new international standard series IEC 61850 is applied and extended to meet the requirements for almost the whole electrical energy supply chain, especially outside substations. Several activities are under way in the domains of power generation (wind power plants, hydro power plants, and decentralized energy resources), power transmission and distribution as well a...

Since a power supply substation of the magnetic levitation train system includes an inverter which is necessary to change the frequency of power, it has a different characteristic comparing to any other railway system. Nowadays, a study is undergoing to determine rating of facilities constituting a power supply system and modeling that system. This paper proposes an analysis model for the power...

Condition monitoring of power substations is a significant issue for the National Electric Power Authority (NEPA) of Nigeria. Current methods for monitoring the condition of high voltage equipment are time consuming and often inaccurate, therefore causing catastrophic damage to the substation equipment. Recent research has demonstrated the efficacy of employing optical fiber sensors in conditio...

The necessary electricity of the workshops and buildings (W&Bs;) located at the metro depot are provided by lighting power substation (LPS). To transmit electricity between LPS and W&Bs;, some trenches should be dig and the requisite cables should be located in the trenches. This paper presents a new mixed integer linear programming (MILP) long-term decision model to find ...

Power management is an important constraint in the design of various loads in industries for automation. So if power consumption increases then the substation monitoring is very important for the purpose of controlling the hardware and software optimization with the help of PLC ladder logic system and SCADA were used. This technique in order to reach strong conclusion about their actual impact ...

The paper discusses automated substation data integration and analysis. Recorded data collected from various substation IEDs is stored into a substation data warehouse that utilizes standardized file formats and database interface. The data warehouse allows different software agents to convert raw data to useful information and represents an interface for functional integration of different app...

The growth of a country is scaled by the amount of energy it consumes. In the developing India, with the rise of population, increasing number of cities and demanding villages, caused to set up transmission lines with higher capacity. Inter-ties were connected through the transmission lines to lighten every city and village, thus making the whole system complex. This complex system required a r...

In order to assure the uninterrupted power supply of high speed railway, the reliability assessment of traction substation is essential at the design stage. Based on the system reliability engineering theory, a new system reliability analysis method called the GO-FLOW methodology is applied in the reliability assessment of traction substation of high speed railway. Considering failure and dynam...
