One kind is provided in this embodiment of the present invention send receiving end power grid wind/luminous energy to combine adjusting analogue system and method with Hydropower Unit.
It is specifically described below.
Receiving end power grid wind/luminous energy is sent to combine adjusting with Hydropower Unit as shown in Figure 1, one embodiment of the invention provides one kind
Analogue system, comprising: the Hydropower Unit model 2 of the wind of sending end power grid/luminous energy model 1 and receiving end power grid, wind/light of sending end power grid
The Hydropower Unit model 2 of energy model 1 and receiving end power grid is electrically connected, wind/luminous energy model 1 and receiving end power grid water power of sending end power grid
2 combined operating of unit model is exported by wind/luminous energy model 1 that the Hydropower Unit model 2 of receiving end power grid compensates sending end power grid
The fluctuation of target power.
Wherein, the Hydropower Unit model 2 of receiving end power grid includes hydraulic turbine model 21, conduit models 22, hydraulic generator

Governor in quasi- Adaptive System of Water-Turbine Engine, 242 model of mechanical hydraulic follower system is for simulating in Adaptive System of Water-Turbine Engine
Mechanical hydraulic follower system.
Specifically, it is constructed in the embodiment of the present invention and receiving end power grid wind/luminous energy is sent to combine adjusting emulation system with Hydropower Unit
System, 2 combined operating of wind/luminous energy model 1 and Hydropower Unit model compensate wind/luminous energy model 1 by Hydropower Unit model 2 and export
Target power fluctuation.Wherein, wind/luminous energy model refers to wind-powered electricity generation/photovoltaic energy power output model in sending end power grid, mainly
Using wind-powered electricity generation/photovoltaic energy power curve in sending end power grid.
Under normal circumstances, conventional hydropower unit model can be used directly to the mesh of the new energy output such as compensation wind-powered electricity generation/photovoltaic
The fluctuation of power is marked, however there is still a need for think over existing limiting factor in engineering practice.In the embodiment of the present invention
In to making following hypothesis:
1) ignore the limitation in conventional hydropower unit vibration area
There are one or more vibrating areas in practical Hydropower Unit, Hydropower Unit is run in vibrating area in the process of running
When, the vibration of different parts, throw, pressure pulsation amplitude are larger, this will seriously affect the safe and stable operation of Hydropower Unit.Cause
This, Hydropower Unit in engineering practice can divide vibrating area according to different heads, unit output according to certain standard, and
Vibrating area is avoided in setting in Automatic Generation Control (Automatic Generation Control, AGC) system control strategy, is prevented
Only during Hydropower Unit on-load long-play in vibrating area.Although vibrating area brings one to the regulating power of Hydropower Unit
Fixing is rung, but is available with the start and stop combination of the vibrating area complementarity of different Hydropower Units, Hydropower Unit, reduces single water power
The influence of the vibrating area of unit, the regulating power for improving hydroelectric power plant or Hydropower Plant Group.In view of vibrating area is to more Hydropower Units
Or the combined effect of Hydropower Plant Group is more significant, it is not intended that the influence of the factor in the embodiment of the present invention.
2) ignoring is influenced by DC power transmission line in sending end power grid
It should theoretically consider safe and stable operation, the DC power transmission line active power of extra high voltage direct current transmission line
The fluctuation of the target power of electrical/optical energy model output with the wind, but consider most extra high voltage direct current transmission lines often basis
" one-part form " or " three-stage " firm power Plan Curve adjusts direct current transmission power, so not considering in the embodiment of the present invention
The influence of DC power transmission line directly utilizes sending end power grid wind/photovoltaic energy power curve and receiving end in Hydropower Unit side
Hydropower Unit combined operating, the maximal regulated ability that analysis receiving end power grid Hydropower Unit has, and then provide receiving end power grid water
The degree of fluctuation of the target power for the sending end power grid output that motor group can allow for.
3) ignore power swing/oscillation problem in hydroelectric generating set load adjustment process
Theoretically Hydropower Unit is adjusted rapidly, can compensate for power swing, the intermittence of the new energy such as wind-powered electricity generation/photovoltaic.
But it is likely to occur following two different situations.
Situation one: due to hydroelectric generating set load adjusting starts/ending phase adjustment speed is slow, load compensation it is initial/
Ending phase be likely to occur hydroelectric generating set load control lag in wind-powered electricity generation/Photovoltaic new energy power swing, to fluctuation new energy
Power swing compensation not in time the phenomenon that, the new energy power such as power swing and wind-powered electricity generation/photovoltaic of Hydropower Unit under extreme condition
It differs greatly on wave time, then may aggravate the power swing for sending receiving end power grid.It, may if the phenomenon periodically occurs
It triggers entire electric system and carries out power low-frequency oscillation alarm.
Situation two: due to the acute variation of the new energy such as wind-powered electricity generation/photovoltaic, hydroelectric generating set load adjustment speed is difficult to adapt to newly
Energy source power quickly changes, i.e. the acute variation relative to new energy power, Hydropower Unit power swing lag；Although hydroelectric machine
Group is adjusted in all one's effort, but the result is that the fluctuation of the fluctuation and Hydropower Unit power regulation of new energy is overlapped mutually, more plus
The acute power swing for sending receiving end power grid.
Therefore, Hydropower Unit is related only in the embodiment of the present invention to the tracking performance of the new energy such as wind-powered electricity generation/photovoltaic, is ignored
Influence of the performance of hydroelectric generating set load itself to simulation result.
4) ignore hydroelectric units primary frequency modulation and AGC pulls problem repeatedly
In engineering practice, different hydroelectric power plants are using different primary frequency modulation and AGC system frequency modulation coordination plan between the two
Slightly or primary frequency modulation is preferential or primary frequency modulation acts shielding AGC system frequency modulation or the primary tune of AGC system frequency modulation movement shielding
Frequently or primary frequency modulation is superimposed with the frequency modulation target of AGC system frequency modulation.Repeatedly occur primary frequency modulation and AGC system in engineering practice
Frequency modulation mutual switching between the two, the phenomenon that will lead to power swing, therefore different coordinations are not considered in the embodiment of the present invention
One of coordination strategy is only chosen in influence of the strategy to sending receiving end grid power to fluctuate.Preferably, the present invention is implemented
Adaptive System of Water-Turbine Engine model is superimposed realization with the frequency modulation target of Automation generation control system frequency modulation by primary frequency modulation in example
The frequency of the Hydropower Unit model is adjusted.
5) ignore the factors bring power swing problem such as pressure pulsation, vibrating area, water hammer
In engineering practice, governor is incorporated into the power networks under aperture regulation mode, due to pressure pulsation, vibrating area, water hammer etc.
The influence of factor, Hydropower Unit the phenomenon that there are power swings during Load Regulation, trigger entire electric power under serious conditions
Low frequency oscillations alarm.The power swing under aperture regulation mode in add drop load process is not considered in the embodiment of the present invention,
Governor model is incorporated into the power networks in power mode.
6) ignore influence of the Hydropower Unit difference head to Load Regulation speed, Load Regulation depth
The maximum power of Hydropower Unit is influenced by head in engineering practice, and the maximum of Hydropower Unit goes out under different heads
The corresponding guide vane servomotor stroke of power, maximum output is different, and guide vane servomotor stroke changes not during corresponding Load Regulation
Together, i.e., there is influence to the speed of governor model in head difference.But this is not the emphasis studied in the embodiment of the present invention, because
Influence of the head to Hydropower Unit regulating power is not considered in this embodiment of the present invention.
7) ignore and frequently adjust caused structural fatigue and destruction for consumption new energy Hydropower Unit
There are certain service lifes for the metal structure of Hydropower Unit, frequently quickly adjust and frequently adjust unit gold at a slow speed
Belong to the dynamic stress different from that structure is born in Dynamic Regulating Process, the abrasion speed of Hydropower Unit key metallic components
Also can be different, Hydropower Unit from the aspect of theoretically should be from configuration aspects, material property in water power-wind-powered electricity generation combined operating
Ability to bear, but this is not the emphasis studied in the embodiment of the present invention, therefore above-mentioned factor is not considered in the embodiment of the present invention
Influence to Hydropower Unit regulating power.
On the basis of above-mentioned hypothesis, Hydropower Unit model includes hydraulic turbine model, diversion system in the embodiment of the present invention
Unite model, hydrogenerator model and Adaptive System of Water-Turbine Engine model, Adaptive System of Water-Turbine Engine model include governor model and
Mechanical hydraulic follower system model.Hydropower Unit model is simulated by above-mentioned concrete model, it is electric to receiving end is sent to realize
