Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention In attached drawing, technical solution in the embodiment of the present invention is explicitly described, it is clear that described embodiment is the present invention A part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not having Every other embodiment obtained under the premise of creative work is made, shall fall within the protection scope of the present invention.
In the prior art, although to the Hydropower Unit in receiving end power grid for compensate sending end power grid power swing it is feasible Property, wind-powered electricity generation-water power management and running studied, but new energy engineering method extensive for trans-regional compensation of hydropower lack Further investigation and discussion.Based on this, the embodiment of the present invention provides a kind of Hydropower Unit regulation performance test method, and this method is applicable in In the system in the operation of sending end new energy-receiving end power grid Hydropower Unit cogeneration, in the feelings of sending end new energy power swing Under condition, the regulation performance of receiving end Hydropower Unit compensation new energy power swing is tested, to obtain the adjusting of Hydropower Unit Performance.Referring to Fig. 1, this method comprises:
101, target power is adjusted according to joint and sets the new energy power swing curve of period, calculate every hydroelectric machine Organize power given value within the set period.
Specifically, referring to fig. 2, it is the new energy power of sending end and the Hydropower Unit of receiving end that joint, which adjusts target power Ps, The sum of power.Due to needing to obtain regulation performance of Hydropower Unit compensation sending end new energy in the case where fluctuation.It therefore, can be with Steady state value is set by Ps, i.e., within the setting period, the value of Ps is remained unchanged.And the power of new energy can be actual power It (is illustrated so that new energy power is wind-powered electricity generation realtime power Pw as an example in Fig. 2 and Fig. 5, the embodiment of the present invention does not limit this It is fixed), during the test, new energy actual power can be simulated using new energy power swing curve.New energy function The rate curve of cyclical fluctuations can indicate the fluctuation situation of the new energy power in the setting period, can specifically include each in the setting period The new energy performance number at moment.Can have certain time interval, such as 1 minute between the two neighboring moment, the present invention is implemented Example is not construed as limiting this.Target power and new energy power swing curve are adjusted based on joint, every water power can be calculated The power given value at each moment within the setting period of unit.It should be noted that the quantity of Hydropower Unit can be one Or more, the embodiment of the present invention is not construed as limiting this.Power given value is the performance number it is expected Hydropower Unit and capable of exporting.
102, it is adjusted according to power of the power given value to Hydropower Unit, record Hydropower Unit is within the set period Power measured value.
Specifically, it after obtaining power given value, can be adjusted based on power of the power given value to every Hydropower Unit Section.The embodiment of the present invention is not construed as limiting specific power regulation mode, specifically can working principle and type based on Hydropower Unit Number etc. be adjusted.After adjusting, the exportable corresponding power measured value of Hydropower Unit, the i.e. power of Hydropower Unit reality output Value.In addition, other than recording power measured value, adjustment speed, the amplitude of accommodation and the time-lag effect of also recordable Hydropower Unit The data such as parameter.
103, by the way that power given value and power measured value to be compared, the regulation performance test knot of Hydropower Unit is obtained Fruit.
Specifically, since the power of Hydropower Unit reality output may not be able to track the power waves of new energy completely It is dynamic, i.e., it can not necessarily fully achieve joint adjusting target power and remain unchanged.Therefore, the function of the synchronization in the period is set Rate given value and power measured value certainly exist certain deviation.It therefore, can be by the power given value and power at each moment Measured value is compared, if the two difference it is smaller, show regulation performance of the Hydropower Unit in new energy power swing compared with By force, Hydropower Unit can preferably compensate the power swing of new energy.On the contrary, showing that Hydropower Unit exists if the two difference is larger Regulation performance in the case of new energy power swing is weaker, and Hydropower Unit cannot compensate well for the power swing of new energy.Cause This can obtain the regulation performance test result of Hydropower Unit by comparing power given value and power measured value.
Method provided in an embodiment of the present invention, by being adjusted according to power of the power given value to Hydropower Unit, and Power given value is compared with the power measured value of physical record, obtains the regulation performance test result of Hydropower Unit, from And regulation performance of Hydropower Unit in the case where new energy power swing is experimentally obtained, and further demonstrate Receiving end Hydropower Unit dissolves the effect of new energy, for trans-regional new energy-Hydropower Unit joint is adjusted and mentioned in real time in engineering practice Reference is supplied.
Content based on the above embodiment provides a kind of according to joint adjusting target power as a kind of alternative embodiment And the new energy power swing curve of setting period, calculate the side of every Hydropower Unit power given value within the set period Method, including but not limited to:
