Full factory's Automatic Generation Control optimization device (1) based on the received full factory's load from grid side always instruct and it is received respectively
The operational efficiency of a unit calculates the load value of each unit, and the sharing of load instruction for forming each unit is sent to accordingly
Generator set controller, so that generator set controller controls corresponding unit generation according to sharing of load instruction；
The load distribution strategy specifically:
After full factory's Automatic Generation Control optimization device (1) receives full factory's load instruction of grid side, according to the electricity received
Full factory's load instruction calculated load changing value of full factory's load instruction of net side and the last grid side received, and work as load
When changing value >=(operating unit number of units × 10) MW, then total rate of change of all units is that (operating unit number of units × single machine holds
Amount × 1%) MW/min, when distribution need to meet single unit rate >=(single-machine capacity × 1.5%) MW/min；
When full factory's Automatic Generation Control optimizes device (1) received load variations value < (operating unit number of units × 10) MW, then
Total rate of change is (operating unit number of units × single-machine capacity × 1.5%) MW/min, when distribution need to meet single unit rate >=
(single-machine capacity × 1.5%) MW/min；
The load distribution strategy be efficiency of generating unit allocation strategy, regulations speed allocation strategy, pondage allocation strategy,
Normalize any strategy in index allocation strategy and fixed point power allocation strategy；
The efficiency of generating unit allocation strategy specifically: by the generating efficiency of each unit in all unit generation gross efficiencys
Ratio always instruct and be multiplied with full factory's load, obtain the load value of each unit；
The regulations speed allocation strategy specifically: by the regulations speed of each unit in the total rate of adjusting of all units
Ratio is always instructed with full factory's load to be multiplied, and obtains the load value of each unit；
The pondage allocation strategy specifically: by the pondage of each unit in the adjusting total capacity of all units
Ratio is always instructed with full factory's load to be multiplied, and obtains the load value of each unit；
The normalization index allocation strategy specifically: always refer to the weight coefficient of preset each unit and full factory's load
It enables and being multiplied, obtain the load value of each unit；
The fixed point power allocation strategy specifically: the fixed point power difference of each unit is poor in the fixed point power of all units
Accounting in value is always instructed with full factory's load to be multiplied, and obtains the load value of each unit；The fixed point power difference is to set in advance
The difference of fixed unit load value and actually measured unit load value.
