signal to the control electronics 40 which in response to receiving the generated signal may stop the operation of the wind power installation it is to be appreciated that in some embodiments the counter 38 is integrated in the computing device 36 fig6 is a flow chart illustrating a method 50 according to one embodiment the method 50 includes determining if ice accretion has been detected at step 52 if ice accretion has been detected an associated one or more wind power installations may be stopped from operating or stoppage may be maintained as shown by step 54 the method 50 may further include determining if ice accretion is still detected as indicated by step 56 if ice accretion is still detected then the method continues back to maintaining stoppage of the wind power installation at step 54 if however ice accretion is not detected then the method includes determining if ice accretion is expected to continue to occur as indicated by step 58 if ice accretion is expected to continue to occur the method continues back to maintaining stoppage of the wind power installation as step 54 alternatively if no ice accretion is expected to occur the wind power installation may be started after a time delay as indicated by step 60 if on the other hand ice accretion was not detected at step 52 the method includes determining if ice accretion is expected to occur at step 62 if it is determined that ice accretion is not expected to occur.
