Embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment, belongs to the scope of protection of the invention.
What deserves to be explained is inventor during the embodiment of the present invention is realized, has found the tune of the prior art that draws water
The overall procedure that phase turns pumping operation mode can be as shown in Figure 2.Wherein, it is notable that the prior art needs to judge to be vented back
Water whether complete and ball valve whether standard-sized sheet；So as to be completed in exhaust backwater, and during ball valve standard-sized sheet, involution governor phase modulation pattern.
And the prior art has the disadvantage that, that is, need after waiting until ball valve standard-sized sheet, just open guide vane.Yet with ball valve
Open to after 97.2% or so aperture, its opening speed substantially slows down, and ball valve opening process oscillogram is as shown in Figure 3.Ball valve from
97.2% to 100% aperture takes about 26s, and the problem of rear guide vane fails to open in time is completed so as to runner occur and make pressure.In this way,
After the completion of runner makes pressure, fail to open guide vane in time, cause unit to be run for a long time in the state of larger vibration, this is to unit
Fatigue rupture effect can be produced.Also, after the completion of runner makes pressure, fail to open guide vane in time, the phase modulation that causes to draw water is to work of drawing water
The conversion time of condition is long.
To overcome above-mentioned problem of the prior art, taken out as shown in figure 4, the embodiment of the present invention provides a kind of pump-storage generator
Water phase modulation turns the control method of pumping operation mode, including：
Step 101, judge whether pump-storage generator full in working conditions of phrase modulation operation of drawing water, pump-storage generator respectively
The phase modulation that draws water enough turns pumping operation mode condition, and the phase modulation that draws water of pump-storage generator turns whether pumping operation mode instruction sends.
If step 102, pump-storage generator are in working conditions of phrase modulation operation of drawing water, and pump-storage generator meets the phase modulation turn that draws water
Pumping operation mode condition, and the phase modulation that draws water of pump-storage generator turns pumping operation mode instruction and has been sent from, then water pump side is protected in selection
To startup, involution is protected in phase modulation pattern of drawing water.
Step 103, judge whether the oil pressure of governor and ball valve oil gear is normal.
If step 104, governor and the oil pressure of ball valve oil gear are normal, exhaust backwater sub-process is performed, opens ball
Valve.
Step 105, judge to be vented whether backwater sub-process is completed, and whether ball valve aperture is more than pre-set percentage
Numerical value.
Specifically, the pre-set percentages are 97%.
Exhaust backwater sub-process can determine whether to make whether pressure is completed herein, it can specifically judge in the following way：
No leaf area pressure is more than P1 and active power is less than N1 (unit MW), then makes pressure and complete.Wherein P1 and N1 is advance
The definite value of setting.
Therefore, when being vented backwater completion, the necessary condition that guide vane is opened meets.
If step 106, exhaust backwater sub-process are completed, and ball valve aperture is more than pre-set percentages, then into
Row timing.
Step 107, when timing time reaches pre-set time threshold, carry out involution governor phase modulation pattern.
Specifically, the pre-set time threshold is 2 seconds.
Guide vane is opened in step 108, control governor water pump direction.
Step 109, selection are protected in water pump pattern.
Step 110, judge ball valve whether standard-sized sheet.
If step 111, ball valve standard-sized sheet, the involution phase modulation that draws water turns pumping operation mode flow so that ball valve instruction failure is opened,
So that pump-storage generator enters stable state of drawing water.
As it can be seen that the embodiment of the present invention can use one ball valve aperture node signal of increase, which corresponds to ball valve aperture
Adjust as 97%.In this way, after performing exhaust backwater sub-process and opening ball valve, whether delay judgement exhaust backwater is completed, and ball valve is opened
Whether degree reaches 97%, if both mutually with to be true, performing delay 2 seconds, then perform involution governor phase modulation pattern, adjust successively
Leaf is convinced in fast device water pump direction by patient analysis, selection is protected in water pump pattern.Judge again ball valve whether standard-sized sheet, if standard-sized sheet, unit enter take out
Water stable state.After implementing the embodiment of the present invention, shown in the vertical line in wicket opening time point below figure 5, this compares prior art
Wicket opening time point is advanced by 14.5s.
A kind of pump-storage generator provided in an embodiment of the present invention phase modulation that draws water turns the control method of pumping operation mode, is performing
Backwater sub-process is vented, when opening ball valve, can interpolate that whether exhaust backwater sub-process is completed, and whether ball valve aperture is more than in advance
The percentages first set；In this way, completed in exhaust backwater sub-process, and ball valve aperture is more than pre-set percentage number
Value, can carry out timing；When timing time reaches pre-set time threshold, involution governor phase modulation pattern is carried out；Into
And governor water pump direction is controlled to open guide vane；Selection is protected in water pump pattern；Judge ball valve whether standard-sized sheet；And in ball valve standard-sized sheet
When, the involution phase modulation that draws water turns pumping operation mode flow so that opens ball valve instruction failure so that pump-storage generator enter draws water it is steady
State.The embodiment of the present invention can shorten the conversion duration that the phase modulation that draws water turns pumping operation mode, can improve the response speed to grid requirements
Degree.Also, the embodiment of the present invention can open guide vane in time after the completion of runner makes pressure, reduce unit under larger vibration
Run time, reduces the risk that fatigue rupture occurs for unit.
