Automation is “the application of machines to tasks once performed by human beings, or increasingly, to tasks that would otherwise be impossible”, Encyclopaedia Britannica [1]. The term automation itself was coined in the 1940s at the Ford Motor Company. The idea of automating processes and systems started many years earlier than this as part of the agricultural and industrial revolutions of th...

The last few years have seen considerable investment in the security of industrial control systems. In the power sector, there has been a focus on operational measures directed by NERC, while technical solutions have been proposed through the IEC and the ISA. Many of these proposals use cryptography to secure communications, so that some of the defensive effort can be moved from the perimeter t...

Substation optimization involves positioning a substation(s) at the most suitable point with minimum cost. In this study, multiple data were collected from Turkish Electric Distribution Incorporated Company (TEİAŞ) for substation in Eryaman region. The substations will be placed straight points. Using capacity of substations, power, voltage drops, and service interruptions calculated 10-year pl...

Abstract When lightning intrudes into the over-voltage in 500 kV substation, wave will be introduced substation along line, which seriously affect insulation level of equipment. In this paper, firstly, working principle, characteristics, and current simulation ZnO arrester are described. Then, electromagnetic transient program (EMTP-ATP) used a GIS carried out research to over-voltage, specific...

The noise in substations has become one of the most concerning problems field power grid. In this paper, principle substation layout optimization based on maximum acoustic ray shielding method is established premise sound wave propagation rule complicated air medium to meet requirements relevant national environmental standards for at boundary substation. By establishing simulation analysis mod...

Abstract The intelligent delivery robot for substation maintenance is a kind of equipment power system, which can assist or even replace the artificial to carry in substation. It has important theoretical significance and practical application value automation operation management Substation autonomous navigation motion control key promote its application, based on this, this paper proposes veh...

The article presents the transients analysis of the substation grounding systems and transmission line tower footing resistances which can affect to the back-flashover (BF) or overvoltage across insulator chain in an HV power systems by using EMTP-RV software. The related transient modeling of the grounding systems is based on a transmission line (TL) model with considering the soil ionization....

Aiming at the different sampling rates of multiple sensors for the real-time detection system of heat faults in high-voltage equipment in substation, the step by step prediction fusion algorithm based on synchronous sampling data was used to rapidly calibrate the location of thermal faults. And a new method that using infrared thermal imager together with CCD (Charge Coupled Device) camera and ...

Tap changing operations of multiple transformers at a substation is a complex problem due to issues in controlling the parallel operations of the transformers involved, differences in manufacturer’s design and inaccuracy of the measures. In earlier work Artificial Neural Network (ANN) based tap changer controller has been developed to overcome these difficulties and improved results have been s...

Digital substations are mostly important in the future of the electric power industry which makes their testing a critical process to ensure the required reliability and security of the grid. The paper introduces the definition of a digital substation and efficient testing, as well as the requirements for isolation during testing. It later describes testing related features in IEC 61850 Edition...
