Description

Wind turbine generator set operation parameter control method, system, equipment and storage medium
Technical Field
The invention belongs to the field of wind power generation, and relates to a method, a system, equipment and a storage medium for controlling operating parameters of a wind turbine generator.
Background
The control strategy of the wind generating set is used as the core of the control system, and the wind generating set is determined to give different control instructions under different wind speeds and different working conditions. Because the wind speed change and the working condition change are not constant, the control parameters required by the control strategy under different conditions are difficult to represent by one unified control parameter, so that the control parameters are generally determined by adopting a two-dimensional table look-up mode in the conventional control strategy at present. In each actually occurring control period, the table is looked up to calculate the control parameter corresponding to the signal according to the measured signal in the set range. That is, there are two fixed endpoints in each segment interval, and linear interpolation is performed at the two fixed endpoint segments to obtain the corresponding control parameters. However, due to the different end point setting values between different segment intervals, the control parameters obtained by linear interpolation may have large changes when a large measurement signal changes, and the sudden control parameter change is not favorable for the smooth operation of the wind generating set due to the rapid and complicated pneumatic load change. Therefore, it is necessary to adjust the interpolation mode of the control parameters, so that the unit can stably interpolate the corresponding control parameters under different conditions.
The existing technical scheme aiming at the problem comprises the following steps: the control parameter setting of a one-dimensional array is replaced, and the corresponding control parameters are determined by linear interpolation in each control period according to different conditions in a two-dimensional table look-up mode. However, in the existing interpolation mode, the curve is not smooth enough, and the slope change at the connection point is too large, so that the control parameters interpolated in a continuous control period may change greatly to influence the control function effect.
Disclosure of Invention
The invention aims to overcome the defect that the control function effect is influenced by the fact that the interpolated control parameters change greatly in a continuous control period due to unsmooth curves and overlarge slope changes at connecting points in the interpolation mode in the prior art, and provides a wind turbine generator operation parameter control method, system, equipment and storage medium.
In order to achieve the purpose, the invention adopts the following technical scheme to realize the purpose:

and if the current pitch angle is larger than the termination pitch angle, calculating a pitch angle instruction by using a proportional gain parameter setting value, an integral time constant or a differential coefficient corresponding to the termination pitch angle.
Preferably, in the pitch angle instruction calculation process in step 2), firstly, a proportional gain parameter setting value, an integral time constant or a differential coefficient corresponding to the start pitch angle and the end pitch angle in the current control period is obtained according to the start pitch angle, the end pitch angle and the current pitch angle, and the proportional gain parameter setting value, the integral time constant or the differential coefficient is applied to a rotating speed-pitch loop PID control algorithm to calculate the pitch angle instruction.
Preferably, the specific calculation process of the proportional gain parameter setting value in step 2) is as follows:
based on the current pitch angle PA and the initial pitch angle PA0And ending pitch angle PA1The following monomials are obtained:
*PA^3*2 (1)
-3*PA^2*PA0 (2)
-3*PA^2*PA1 (3)
6*PA*PA0*PA1 (4)
PA0^3 (5)
-3*PA0^2*PA1 (6)
(PA0-PA1)^3 (7)
summing the formula (1) to the formula (6) to obtain the formula (8), wherein the formula (8) is
2*PA^3+3*(PA0+PA1)*PA^2+6*PA1*PA0*PA+(PA0-3*PA1)*PA0*PA0 (8)
Based on the equations (7) and (8), the proportional gain parameter setting value in the current control period is obtained.

Preferably, the data processing module comprises a judging unit and a monomial establishing unit;
the judgment unit is used for judging the relationship between the current pitch angle and the initial pitch angle and the ending pitch angle, and if the current pitch angle is smaller than the initial pitch angle, the proportional gain parameter setting value, the integral time constant or the differential coefficient corresponding to the initial pitch angle are used for calculating a pitch angle instruction; if the current pitch angle is larger than the termination pitch angle, calculating a pitch angle instruction by using a proportional gain parameter setting value, an integral time constant or a differential coefficient corresponding to the termination pitch angle;

Compared with the prior art, the invention has the following beneficial effects:
the invention discloses a spline interpolation-based wind turbine generator operating parameter control method, which adopts a cubic spline interpolation mode to carry out interpolation calculation on a current measurement signal and continuous control parameters in segmented interval endpoints thereof, thereby avoiding the influence of control parameter change on stable operation of a fan caused by the problem of the interpolation mode. In the mode of acquiring the control parameters by two-dimensional table lookup, the corresponding control parameters are calculated through the left end point and the right end point of each segmented interval, so that the smoothness of the curve is ensured, and the problem of control function stability caused by overlarge control parameter change at the end points of each segmented interval is avoided to the greatest extent. The invention adopts a cubic spline interpolation mode, and overcomes the defects that the curve is not smooth enough and the slope change at the connecting point is overlarge due to the adoption of linear interpolation in the traditional mode, so that the control function effect is influenced by the fact that the interpolated control parameters can be greatly changed in a continuous control period. Because the control parameters are obtained in a two-dimensional table look-up mode generally depending on the measurement signals of the fan, the measurement signals change along with the fluctuation of the wind speed, and the cubic spline interpolation is applied to the control of the operation parameters, so that the violent change of the control parameters of the interpolation caused by the irregular violent fluctuation of the wind speed can be avoided.
Furthermore, in each control parameter table look-up segmentation interval, the expression between two adjacent points is a cubic polynomial. At each point in each control parameter lookup table segment interval, its derivative and its second derivative are continuous within the segment interval fixed endpoints. And the left end point and the right end point in each control parameter table look-up segmented interval are in a natural boundary mode, namely the second derivative of the end points is 0, so that the stability of each segmented control parameter table look-up is ensured.
Furthermore, a cubic spline interpolation mode is adopted to calculate the Kp value in the rotating speed-variable pitch control PID parameter corresponding to the current pitch angle, but the Kp value is not limited, and other values such as an integral time constant Ti and a differential coefficient Kd are also applicable.
The invention discloses a spline interpolation-based wind turbine generator operation parameter control system, which comprises a data acquisition module, a data processing module and a pitch angle command calculation module, wherein the data acquisition module is used for acquiring a current pitch angle and a control parameter list, acquiring a control period based on the control parameter list, and acquiring an initial pitch angle and a final pitch angle in the control period, and the data processing module is used for calculating based on the initial pitch angle and the final pitch angle, respectively acquiring a proportional gain parameter setting value, an integral time constant or a differential coefficient corresponding to the initial pitch angle and the final pitch angle, and calculating the pitch angle command by using the proportional gain parameter setting value, the integral time constant or the differential coefficient. Compared with the higher-order spline interpolation, the cubic spline interpolation adopted by the system can be completed only by less calculation and storage.
