Protection systems must operate in a very short time range. Since fault detection should be very fast, local measurement based algorithms are mostly used; communication based algorithms lack the needed speed as a result of the communication time delay. This way, a ROCOV algorithm is proposed in this paper. This algorithm is analysed for different fault conditions. %K HVDC grid %K ROCOV %K Fault detection %K Protection system %K VSC doi 10.24084/repqj18.260 %U http://hdl.handle.net/11556/1004 %~ GOEDOC, SUB GOETTINGEN
