I was reading the mLife manual and came across the DEL frequency term as shown below. Can you help me understand what does that term mean and its importance.

Dear @Karthik,

A short-term DEL is the fixed load range (twice amplitude) at a fixed frequency that results in the same damage (in a Minerās rule sense) as the stochastic signal. f^eq in the documentation you reference is this fixed (user-defined) frequency. Often f^eq is set to 1 Hz in wind energy applications.

Thanks Jason. This helps.

Dear @Jason.Jonkman

I have one more query, can you help me understand the concept of āelapsed timeā

Tl: total elapsed time for all power production time series

Tj: total elapsed time of time series j

Dear @Karthik.Prakash,

āElasped timeā simply refers to how long the oscillation lasts for. T_j is the length of simulation j (in seconds). T_l is the total length of all simulations in bin l (in seconds).

Best regards,
