This paper presents a support vector machine (SVMs) approach for locating and diagnosing faults in electric power distribution feeders. The proposed approach is based on the measurements available at the substation and remote terminal units (RTUs). To illustrate the proposed methodology, a practical distribution feeder emanating from 132/11KV-grid substation in India with loads is considered. T...

Within the hierarchy of power system, distribution system automation plays a crucial role to provide reliable service to customers. Though initially computer aided automation started as substation monitoring system (SMS) just for monitoring some key parameters such as voltage and currents of different components in a substation, the technological advancement has enabled to have access to more f...

During this field survey, we measured and recorded a few quality parameters of wireless communication in a substation switchyard. A microprocessor-based measurement system was used for data collection and analysis. We investigated long-term noise variation in this specific environment. Based on our measurement and post-processing analysis we conclude that the so-called Classic/Bayesian assumpti...

The ISO/IEC 61850 protocol for substation automation is a key component for the safe and efficient operation of smart grids, whilst offering a substantial range of functions. While extension standards, particularly ISO/IEC 62351 provide further security controls, the baseline protocol offers the assurances of access control and availability. In this paper a systematic study of selected aspects ...

Original scientific paper As a synchronization method, IEEE1588 standard has been applied in substation, it should be tested and verified ensure synchronization accuracy and node interoperability. A comprehensive testing method for the IEEE1588 is proposed in this paper. Furthermore, IEEE1588 clock testing platform is built to support the proposed testing method. Based on the analysis of the cl...

superconductor fault current limiter (sfcl) is an effective device to suppress high fault currents. this paper presents a comparative study of resistive and inductive fault current limiters from transient stability point of view.  appropriate location and type of the limiters in a hv substation is selected by a qualitative approach based on the equal area criterion. study system is simulated by...
