Utilization of a mixture of CTs and current sensors in line differential protection applications
(CIRED, 2019-06-03)
- conferenceObject
The popularity of Rogowski sensors is increasing due to their advantages over conventional CTs. Consequently, network utilities may sometimes end up facing a question whether it would be possible to use line differential ...
Voltage and current THD in microgrid with different DG unit and load configurations
(CIRED, 2008-06-23)
- conferenceObject
After microgrid transition from the normal operation to the islanded operation the system impedance changes considerably and it affects on the harmonic voltages of the microgrid. In this paper the voltage ...
Novel protection approach for MV microgrid
(CIRED, 2011-06-06)
- conferenceObject
The amount of distributed generation (DG) connected to medium voltage (MV) networks is expected to increase continuously. This trend creates a good opportunity to use MV feeders as microgrids. Normally ...
Active network management scheme for reactive power control
(CIRED, 2018-06-07)
- conferenceObject
In the future new options to provide needed technical ancillary services locally and system-wide by distributed energy resources (DER) are needed. One ancillary service which DER could provide is the reactive power management ...
