Description

It is applicable to AGC unit dynamic combined concocting method and the device of ACE Discrete control

Technical field

The present invention relates to power system Automatic Generation Control (Automatic Generation Control, AGC) technology Field, is applicable to AGC field territory control deviation (Area Control Error, ACE) Discrete control in particular to one AGC unit dynamic combined concocting method and device.

Background technology

The production of electric energy, transmitting, supply and consume and must complete at synchronization, therefore power dispatching station must be at any time Follow the tracks of and timely respond to load variations, by the Effective Regulation to generating set, meeting power supply and demand balance, it is ensured that power system Safe and stable operation.

Owing to power system load is fast changing, manual operation is relied on all to be difficult to from response speed or control accuracy Meet safety, high-quality, economical operation needs, it is necessary to using the control measures of automatization, the most widely used technology is AGC.

For reflection power system active power equilibrium of supply and demand situation in real time, AGC correlation technique defines and is provided with a weight The calculating parameter wanted, referred to as district control deviation (Area Control Error, ACE).Based on control performance standard (Control Performance Standard, CPS), the expression formula that correlation technique is given is:

ACE=20B_iΔf+ΔP_c

Wherein: B_iFor the coefficient of frequency (MW/0.1Hz) of power system control area i, Δ f is power system frequency deviation (Hz), Δ P_cFor interconnection active power deviation (MW) between adjacent interconnected electric power system；Δ f=f-f_s, f is power system Ongoing frequency, f_sFor power system standard frequency；ΔP_c=P_c-P_s, P_cFor the current active power of interconnection, P_sFor interconnection plan Active power.Supply exceed demand in positive ACE reflection, and supply falls short of demand in negative ACE reflection.

The basic function of AGC and effect are by the auto-control to generating set active power, make ACE tend to 0, it is achieved Power supply and demand balance.For effectively organizing regulatable generation assets, smoothly and rapidly eliminate power supply and demand imbalance deviation, keep away Exempting from toning or less stress occur during reducing ACE, correlation technique has divided control section with the order of severity of ACE, including Dead band, normal regulating district, auxiliary adjustment district and cooperation regulatory region.Respectively control section according to ACE and exchange joint speed and pondage Demand, need to organize a number of AGC Unit Combination to become normal regulating, auxiliary adjustment and cooperation regulation echelon, hold respectively Load ACE respectively controls the regulation task of section.

Corresponding to the load variations of power system, power dispatching station is when working out generation schedule a few days ago, generally by controlling The 2% of region peak load～5% carries out estimating and reserve corresponding generating capacity as standby, including the regulation of AGC unit Standby.Owing to pondage and the regulations speed of different units are not quite similar, the regulation performance difference of dissimilar unit is bigger, Therefore correlation technique fails respectively to control the regulatory demand arrangement regulation spare capacity of section for ACE, and do not generate electricity meter a few days ago Specify ACE respectively to control AGC Unit Combination or the unit quantity of section in drawing, the most manually can only be adjusted by Dispatchers on duty Joining, difficulty is big, labor intensity is high in enforcement；In running, along with the change of unit active power, it increases, subtracts the model of power Enclosing (the most upper and lower adjustable capacity) to change therewith, regulations speed is likely to change along with the difference of operating condition, on duty The regulation performance that dispatcher is difficult to each unit of grasp accurate, timely, comprehensive is current, carries out rational allocation at any time, thus exists Unit Combination is unreasonable, the coordination ability is the most abundant, demand response does not mates or regulates the problems such as standby resources waste.

Summary of the invention

In view of this, it is an object of the invention to provide a kind of AGC unit dynamic combined being applicable to ACE Discrete control to adjust Method of completing the square and device, to solve above-mentioned problem.
