3) partial status change explanation
Accidental shutdown：When accidental shutdown judges, no matter whether control is in collection control, as long as having accident resultant signal and machine
Group is in non-shutdown state, is regarded as accidental shutdown, it is to avoid originally control can not judge accidental shutdown problem at existing ground.
At full capacity：Do not repartition whether AGC has been put into, as long as control is controlled in collection and unit is reached under current head
Maximum technology exert oneself and be considered as having reached oepration at full load state.
Dispatch limited load：After collection control puts into operation, dispatch command is assigned generally by AGC, therefore scheduling limited load must
AGC input states must be considered.
Equipment limited load：During general device input collection control control, it should may be at full hair-like state, therefore as unit AGC
Exit, due to the influence of unit self reason, and the maximum technology that is not reaching under current head of unit can be sentenced when exerting oneself
It is set to equipment limited load.
