Description
Technical field
The present invention relates to a kind of coal unit source network regulation frequency method, especially relate to the two frequency modulation method that is full of of a kind of coal unit source based on UCPS net.
Background technology
The power of generation current unit controls assistant service, generally with the accuracy of generator output trace scheduling instruction for primary evaluation foundation.No matter whether favourable or harmful to electric power netting safe running, all to punish the controlling behavior departing from dispatch command.
In order to meet the requirement of power grid frequency modulation and AGC assistant service, generally adopt " stove is with machine " control mode, ensure the AGC power trace performance that unit has had, because boiler hot power has larger operating lag to fire coal, be difficult to the timely balance of accomplishing unit energy, cause unit vapour pressure, steam temperature significantly changes, reduce stability and the economy of unit operation.
1996, NERC proposed the CPS evaluation criterion for controlled area, it with generator output to correcting the contribution degree of mains frequency and ACE for primary evaluation foundation.Take electric power netting safe running as the starting point, the controlling behavior that depart from dispatch command favourable or harmless to electric power netting safe running is not all punished.
Calendar year 2001 starts to carry out control performance evaluation to provincial power network CPS standard.Facts have proved, the Theories and methods of CPS standard has stronger vitality.Also the control performance assessment criteria compatible mutually with provincial power network should be adopted in power plant.
2008 start, and Fujian Electric Power Network starts on probation for generator set control performance UCPS evaluation criterion.Compare with the evaluation method in past, UCPS standard encourages power plant to be power grid security and frequency quality contributes, and decontrols constraint to the generating set of making contributions, and is conducive to improving the economy that generating set runs.
The evaluation method of UCPS:
1) control performance of long-term (as month), should meet: AVG (UCE) ≈ 0
2) UCPS1 weighs the contribution of unit to grid power and FREQUENCY CONTROL, and the larger contribution of its value is larger, and computational methods are as follows.
UCPS1=(2-UCF)
3) UCPS2 weighs the control deviation of unit.Require that the mean value of unit UCE controls within the limits prescribed.That is:
|UCE|≤K
t×L
10
UCE=P
a-P
s(1)
Wherein: UCE is power of the assembling unit deviation (UCE=P
a-P
s), P
afor unit actual measurement active power, P
sfor the target power (or instruction) that control centre sends.Δ f is mains frequency deviation (Δ f=f-50), and f is mains frequency.ACE is district control deviation.
Although had some generating sets UCPS evaluation method at present, also do not adapt to UCPS standard generator set control system.
