110 kV substation relay protection

Design of 132 / 33 KV Substation

The Protection of Substation Communications

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...

Solid insulation drying of 110 kV paper-oil instrument transformers

Influence of moisture on the instrument transformers’ paper-oil insulation and its further maintenance is described in this paper. Improved insulation drying method using vacuum and temperature regulation with definite regulation algorithm of parameters is proposed and analyzed by comparing it with conventional drying method.

Smart Local Backup Protection for Smart Substation

Received Apr 11, 2017 Revised Apr 28, 2017 Accepted Jun 17, 2017 This paper presents a novel smart local backup protection SLBP used for the support and backup of the protective relays in a smart substation. The proposed SLBP is based on the IEC61850 standards and the concept consists of the acquisition of Generic Object Oriented Substation Event GOOSE used for tripping and interlocks exchange ...

Electric and Magnetic Field Computation of 35 Kv Voltage Level of Transformer Substation 35/10 Kv Using the Cdegs Software

Paper presents electric and magnetic field computation of 35 kV voltage level of transformer substation 35/10 kV using CDEGS software. Based on well known theoretical considerations of electric and magnetic fields, a realistic simulation model of transformer station 35/10 kV was develop. All calculations are made for horizontal plane with height of 1,5 m above the soil changing coordinates alon...
