Description
Technical field
The present invention relates to electric system Automatic Generation Control (Automatic Generation Control, AGC) technologies
Field being suitable for AGC field domain control deviation (Area Control Error, ACE) Discrete control in particular to one kind
AGC unit dynamic combined concocting methods and device.
Background technology
Production, transmission, supply and the consumption of electric energy must be completed in synchronization, therefore power dispatching station must be at any time
Load variations are tracked and timely responded to, by the Effective Regulation to generating set, meet power supply and demand balance, it is ensured that electric system
Safe and stable operation.
Since power system load is fast changing, no matter all it is difficult to from response speed or control accuracy by manual operation
Meet safe, high-quality, economical operation needs, it is necessary to which, using the control measures of automation, technology widely used at present is AGC.
To reflect that electric system active power equilibrium of supply and demand situation, AGC the relevant technologies define and be provided with a weight in real time
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 the relevant technologies provide is：
ACE=20BiΔf+ΔPc
Wherein：BiFor the coefficient of frequency (MW/0.1Hz) of power system control area i, Δ f is power system frequency deviation
(Hz), Δ PcInterconnection active power deviation (MW) between adjacent interconnected electric power system；Δ f=f-fs, f is electric system
Current frequency, fsFor electric system standard frequency；ΔPc=Pc-Ps, PcFor interconnection current active power, PsFor tie line plan
Active power.Supply exceed demand for positive ACE reflections, and supply falls short of demand for negative ACE reflections.
The basic function of AGC and effect are so that ACE is tended to 0 by the auto-control to generating set active power, are realized
Power supply and demand balance.Effectively to organize regulatable generation assets, power supply and demand imbalance deviation is smoothly and rapidly eliminated, is kept away
Exempt from occur toning or less stress during reducing ACE, the relevant technologies have divided control zone with the severity of ACE, including
Dead zone, normal regulating area, auxiliary adjustment area and cooperation regulatory region.According to each control zones of ACE to regulations speed and pondage
Demand, need a certain number of AGC Unit Combinations of tissue at normal regulating, auxiliary adjustment and cooperation adjust echelon, hold respectively
Carry on a shoulder pole the adjusting task of each control zones of ACE.
Corresponding to the load variations of electric system, power dispatching station is when working out generation schedule a few days ago, usually by control
The 2%~5% of region peak load estimate and reserved corresponding power generation capacity is as spare, includes the adjusting of AGC units
It is spare.Since the pondage and regulations speed of different units are not quite similar, the regulation performance difference bigger of different type unit,
Therefore the relevant technologies fail to adjust spare capacity for the regulatory demand arrangement of each control zones of ACE, not in power generation meter a few days ago
The AGC Unit Combinations or unit quantity that each control zones of ACE are specified in drawing, can only manually be adjusted by rule of thumb by Dispatchers on duty
Match, enforcement difficulty is big, labor intensity is high；In the process of running, with the variation of unit active power, increase, subtract the model of power
It encloses (i.e. upper and lower adjustable capacity) to change correspondingly, regulations speed may also change with the difference of operating condition, on duty
That dispatcher is difficult to is accurate, timely, grasps the current regulation performance of each unit comprehensively, carries out rational allocation at any time, thus exists
The problems such as Unit Combination is unreasonable, the coordination ability is not abundant, demand response mismatches or adjusts standby resources waste.
