This means systemreliabilitydegraded quickly in that period and needs to be investigated. After that, systemreliabilityimproves in the period from 150 days to 240 days, which is reflected by a decreasing ROCOF. Systemreliabilitydegraded again from 240 days to 310 days and finally improved thereafter
