Frequency regulation The frequency regulation shall not exceed   three   percent   with   the frequency    adjustment    constant Frequency regulation is the rated- load   frequency   divided   into   the difference   between   the   no-load frequency    and    the    rated-load frequency. Short-term, steady-state stability The governing system shall automatically  maintain  the  short- term,   steady-state   frequency   of the   set   within   a   band   width   of plus or minus ½   of  one  percent of the rated frequency at constant load  from  no  load  to  rated  load during  any  30  second  period  of operation.    Rated  load  is  rated KW at 0.8 power factor. Long-term, steady-state stability The  long-term,  steady-state  frequency deviation shall not exceed plus or minus  one  percent  of  the  rated frequency at constant loads from no load to rated load during any 4 hour period of continuous operation except that two frequency excursions beyond the specific.   band   width   for   any   4 hour period are permitted.    Long term,    steady-    state    frequency deviation is defined as the amount the frequency 1-17
