This paper presents performance evaluation of a new architecture for phasor estimation within IEC 61850 substation Process-Bus. To benefit from the raw IEC 61850-9-2 Sampled Measured Values streamed with high sampling rate from various Merging Units at substation bay level, Unsented Kalman Filter is proposed to be utilized in the computation of Phasor at substation process level to enhance the ...
Replacing hardwired connections with digital communications over Ethernet requires new engineering and testing practices. PPL Electric Utilities Corporation (PPL) recently designed, installed, and tested a new high-voltage substation using next-generation relay and control equipment. This next-generation substation (NGS) is based on networked Ethernet intelligent electronic devices (IEDs) commu...
Developments in computer and communication technologies have enabled unmatched integration of a wide range of substation functions within a computer control system. This new class of application has gone through a great deal of effort into achieveing cost-effective, efficient, secure and high performance of the utility power grid substation operations. The integrated Substation Control System (...
This paper presents the design of earthing system for 132 KV substation and simulation for calculation of required parameters. This paper is to provide information pertinent to safe earthing practices in ac substation design and to establish the safe limits of potential difference under normal and fault conditions. The grounding grid system of a practical 220 kV substation is calculated by MATL...
