3) it calculates and retains regulation power
Retain the summation that regulation power is equal to the target power and real-time output deviation of the PLC for being currently executing adjusting.
4) the practical total regulation power in zoning
The practical total regulation power in region is calculated using following strategy：
A) be zero when calculating regulation power, i.e. AGC is in when adjusting dead zone, and the practical total regulation power in region is zero, not into
Row is adjusted；
B) it is adjusted when the absolute value for calculating regulation power and reservation regulation power jack per line, and calculating regulation power is more than to retain
The absolute value of power, then the practical total regulation power in region is equal to the difference for calculating regulation power with retaining regulation power；
C) it is adjusted when the absolute value for calculating regulation power and reservation regulation power jack per line, and calculating regulation power is less than to retain
The absolute value of power, then the practical total regulation power in region is equal to zero；
D) when calculating regulation power and retaining regulation power contrary sign, then the practical total regulation power in region, which is equal to calculate, adjusts work(
Rate and the difference for retaining regulation power.
2, power plant's controller PLC Packet Selection Strategies
According to the maximal regulated work(of the total regulation power of current region and each PLC grouping adjustings sequence, raising and lowering direction
Rate can be a PLC grouping to determine the PLC for needing to participate in adjusting groupings, can also be multiple PLC groupings.
When PLC grouping selections, determine that PLC is grouped order of preference according to grouping adjusting sequence.PLC grouping adjusting sequences are got over
It is small, then it is higher to be selected the priority controlled.
PLC grouping strategies are as follows：
1) setting residual accommodation power=practical adjustments power；
2) it is ranked up according to the unchecked PLC adjusting serial numbers being grouped, selection adjusts that PLC of serial number minimum
Grouping is grouped as current PLC；
If 3) residual accommodation power absolute value is less than rising (decline) direction minimal adjustment power of current PLC groupings,
Then current PLC groupings are selected carries out sequential adjustment, and residual accommodation power is zero；
If 4) residual accommodation power absolute value is more than rising (decline) direction minimal adjustment power of current PLC groupings,
And less than rising (decline) direction maximal regulated power of current PLC groupings, then current PLC groupings are selected is allocated tune
Section, residual accommodation power is zero；
If 5) residual accommodation power absolute value is more than rising (decline) direction maximal regulated power of current PLC groupings,
Then current PLC groupings are selected is allocated adjusting, and residual accommodation power subtracts rising (decline) direction of current PLC groupings most
2) big regulation power turns；
6) it repeats the above process, until residual accommodation power is zero or all PLC groupings are selected.
3, regulation power allocation strategy
When the total regulation power in region is allocated in PLC is grouped between each PLC, if the total regulation power in unappropriated region
Less than the PLC groupings currently chosen minimal adjustment power when, be allocated using sequential adjustment strategy, otherwise using ratio point
It is allocated with strategy is adjusted.
1) sequential adjustment strategy
All PLC for participating in adjusting carry out smallest allocation amount distribution according to serial number, by platform, and carry out sendout and add up, when
Sendout is cumulative to be more than the total regulation power in region, then stops continuing to distribute.
2) pro rate adjusts strategy
The PLC of all adjustings of participating in the distribution is allocated according to regulation power allocation proportion coefficient, is carrying out last time life
The PLC of order is not involved in distribution.In assigning process, detect whether that there are following situations：1. if certain PLC regulation power sendout is small
In minimal adjustment sendout, then the regulated quantity of the PLC is directly distributed by smallest allocation amount, deduct the distribution summation of situation PLC
Afterwards, by dump power, coefficient distributes to other PLC in proportion.2. if certain PLC sendout is more than maximal regulated amount, directly press
Maximum allocated amount distributes the regulated quantity of the PLC, and by dump power, coefficient distributes to other PLC in proportion.It repeats the above process, directly
It is assigned to regulation power.
4, power plant's controller PLC readjustments strategy
To undertaking the power plant controller PLC of plan basic point pattern or artificial basic point pattern, if PLC contributes in real time and plan
The deviation of output has been more than readjustment base band, then when AGC, which is in, adjusts dead zone, refers to if current 10 minutes ACE average values are less than
Set threshold value, then PLC, which is executed, adjusts back strategy, and it is that current planning is contributed that target, which is contributed, and power plant controller PLC is made to return to plan basic point
Or artificial basic point.Meanwhile once PLC plans are changed, readjustment strategy will be also executed, readjustment arrives current planning value.
