Accelerated Loss of Mains Change Programme (ALoMCP)

九州bet9备用网址following the investigation into 9 august 2019 power outage, approximately 550mw of embedded generation was disconnected. in some cases, due to the expected operation of the rate of change of frequency protection system but in other cases because some generators may be operating incorrect protection settings.

to avoid future outages, the alomcp was initiated to amend the loss of mains (lom) settings on generation in gb. in summary these are to remove vector shift (vs) as an allowable lom (loss of mains) technique, and to change any rate of frequency protection (rocof) settings to new, less sensitive values or even disable it.

the vast majority of the sma inverters do not rely on rocof or vs techniques. for that reason, only the following string inverters are on scope of the alomcp.

  • MLX / STP 60-10
  • SHP75-10
  • TLX+6K, TLX Pro+6K, TLX 8K, TLX Pro 8K, TLX+8K, TLX Pro+8K, TLX 10K, TLX Pro 10K, TLX+10K, TLX Pro+10K
  • FLX Pro 17, FLX Pro 15

for the mlx/stp 60-10 and shp75-10, we have defined three country settings for the uk. two of them contain rocof settings in accordance with the g59/3. similarly, for the inverters tlx and flx, the country setting contains rocof settings in accordance with the g59/3. for these inverters, the rocof settings need to be changed or set to disabled as specified in the alomcp.

please refer to the table below to see if you are affected by the alomcp and to see what action, if any is needed.

九州bet9备用网址further guidance will be given for the install base of central inverters in due course.
