Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
It is worth noting that inventor during realizing the embodiment of the present invention, has found the tune in 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；To be completed in exhaust return water, and when ball valve standard-sized sheet, involution governor phase modulation mode.
And the prior art has the disadvantage that, that is, needs after ball valve standard-sized sheet, just opens guide vane.However due to ball valve
It opens to after 97.2% or so aperture, opening speed obviously slows down, and ball valve opening process waveform diagram is as shown in Figure 3.Ball valve from
97.2% to 100% aperture time-consuming about 26s fails the problem of opening in time to runner occur and make pressure completion rear guide vane.In this way,
After the completion of runner makes pressure, fail to open guide vane in time, causes unit to run in the state of larger vibration for a long time, this is to unit
Fatigue rupture effect can be generated.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 too long.
To overcome above-mentioned problem of the prior art, as shown in figure 4, the embodiment of the present invention provides a kind of pump-storage generator pumping
Water phase modulation turns the control method of pumping operation mode, comprising:
Whether step 101 judges pump-storage generator in working conditions of phrase modulation operation of drawing water respectively, and whether pump-storage generator is full
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 issues.
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 that draws water and turns
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 selects protection water pump side
To starting, involution is protected in phase modulation mode of drawing water.
Step 103 judges 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 return water sub-process is executed, ball is opened
Valve.
Step 105 judges to be vented whether return water sub-process is completed, and whether ball valve aperture is greater than pre-set percentage
Numerical value.
Specifically, the pre-set percentages are 97%.
Exhaust return water sub-process can determine whether to make whether pressure is completed herein, can specifically judge in the following way:
No leaf area pressure is greater than P1 and active power is less than N1 (unit MW), then makes pressure and complete.Wherein P1 and N1 is preparatory
The definite value of setting.
Therefore, when being vented return water completion, the necessary condition that guide vane is opened meets.
If step 106, exhaust return water sub-process complete, and ball valve aperture be greater than pre-set percentages, then into
Row timing.
Step 107, when timing time reaches pre-set time threshold, carry out involution governor phase modulation mode.
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 mode.
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 process, 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 be using a ball valve aperture node signal be increased, which corresponds to ball valve aperture
Adjusting is 97%.In this way, whether delay judgement exhaust return water is completed, and ball valve is opened after executing exhaust return water sub-process and opening ball valve
Whether degree reaches 97%, if the two phase be it is true, execute delay 2 seconds, then successively execute involution governor phase modulation mode, adjust
Leaf is convinced in fast device water pump direction by patient analysis, selection is protected in water pump mode.Judge again ball valve whether standard-sized sheet, if standard-sized sheet, unit enters pumping
Water stable state.After implementing the embodiment of the present invention, shown in the vertical line in the following Fig. 5 of wicket opening time point, 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 executing
Be vented return water sub-process, open ball valve when, can judge be vented return water sub-process whether complete, and ball valve aperture whether be greater than it is pre-
The percentages being first arranged；In this way, being completed in exhaust return water sub-process, and ball valve aperture is greater than pre-set percentage number
Value, can carry out timing；When timing time reaches pre-set time threshold, involution governor phase modulation mode is carried out；Into
And it controls governor water pump direction and opens guide vane；Selection is protected in water pump mode；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 process so that open ball valve instruction failure so that pump-storage generator enter draw 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, and the response speed to grid requirements can be improved
Degree.Also, the embodiment of the present invention can open guide vane after the completion of runner makes pressure in time, reduce unit under larger vibration
Runing time reduces the risk that fatigue rupture occurs for unit.
Corresponding to above-mentioned embodiment of the method shown in Fig. 4, draw water storage as shown in fig. 6, the embodiment of the present invention also provides one kind
