The use of process-bus technology, designed in accordance with the IEC 61850 standard, introduces new opportunities for protection and control. However, before the technology can be deployed, adequate tests are required to prove use of the process bus does not have a detrimental impact on the operating performance of future protection, as expressed in terms of dependability, security and operating...
The technical characteristic of smart grid is the realization of Information, digitization, automation and interaction. The relay equipments of intelligent substation are important components of smart grid, under the “four basic requirements of qualities” (sensitivity, selectivity, speed and reliability), its configuration is divided into two layers: process level and substation level. The process...
Apart from the positive technical consequences, the increasing penetration of Distributed Generation (DG) units connected to the distribution network brings new requirements in the protection strategy. Grid disturbances at the transmission level can cause the unwanted disconnection of large amount of DG, leading to undesired power imbalances. This paper examines how transmission network faults can...
Measurements made on an electric utility timekeeping system using standard IRIG-B time code and commercially available equipment are discussed. An attempt is made to determine whether this technique can reliably transfer time accuracies of one millisecond and accuracies of 5 to 50 microseconds. A new method of propagation delay measurement using two synchronized time code generators is introduced...
