About the session
Rate of change of frequency (ROCOF) is a highly discussed topic in several areas of protection. International standards like IEC 60255-181 also deal with this issue. On the one hand this protective function is very important for detecting unwanted islanding in a distribution grid, on the other hand this function is used to protect the system against loss of stability.
During the round table we will address common hurdles for proper measurement of frequency and their approaches to solve these issues. We will discuss how to measure frequency even in dynamic swinging systems with increasing decentralised generation. Furthermore we will talk about the newest developments in IEC 60255-181.
