Description

Decoupling method for rotating speed of floating type double-impeller wind turbine generator and floating platform motion control
Technical Field
The invention relates to the technical field of floating type bilobed wheel wind turbine generator set decoupling control, in particular to a floating type bilobed wheel wind turbine generator set rotating speed and floating platform motion control decoupling method.
Background
At present, wind turbine generators gradually develop to deep open sea, and offshore floating wind turbine generators are the key research and development direction. For the floating wind turbine generator, the requirement on the running state of the generator is higher than that of a fixed generator, the control is more accurate, and the degree of freedom required to be controlled is more, such as the motion control of a floating platform. The floating platform of the floating wind turbine generator has six-direction motion freedom degrees, and in order to restrain the motion of the floating platform or not to excite the negative damping motion of the floating platform (the pitching direction of the floating platform), a generally adopted simpler method is that the design bandwidth of a variable pitch controller is smaller than the motion frequency of the floating platform, so that the variable pitch motion cannot respond to the motion frequency of the floating platform and cannot excite the negative damping motion of the floating platform; but at the same time this brings new problems, namely: the adoption of such a control strategy for pitch systems above rated wind speed can result in high fluctuations in impeller speed and power, extreme over-speeding or over-powering and increased loading of components driven by the impeller speed. Therefore, a set of control logic needs to be designed to switch the floating platform motion control and the rotating speed control, and for the floating type double-impeller wind turbine generator, the strategy is particularly important, namely, the negative damping motion of the floating platform is not stimulated, and the rotating speed can be well inhibited through variable pitch when the rotating speed fluctuation is overlarge.
Disclosure of Invention

In order to achieve the purpose, the technical scheme provided by the invention is as follows: the floating double-impeller wind turbine generator set is a floating platform shared by two fans through a Y-shaped tower, the two fans are respectively arranged on two end parts of the Y-shaped tower through respective yaw driving systems, the bottom of the Y-shaped tower is fixed on the floating platform, and the rotating directions of impellers of the two fans are opposite to offset the centrifugal force of the two fans; in order to coordinate the actions of blades of two impellers to jointly inhibit the motion of a floating platform, the method sets thetaaveIs the mean value theta of blade angles of the impeller 1mean1And mean value theta of blade angle of impeller 2mean2Is characterized by a weighted average of the wind speeds at the centers of the respective hubs of the two impellers, and W is setaveFor the impeller 1 generator speed W1And impeller 2 generator speed W2And configuring two sets of PID control parameters for a variable pitch controller of the unit, wherein the two sets of PID control parameters are respectively PIDfastParameter and PIDslowParameter, wherein PIDfastThe parameter being for controlling speed fluctuations, PIDslowThe parameters are used for inhibiting the floating platform to enable the bandwidth of the variable pitch controller to be smaller than the moving frequency of the floating platform, and the two sets of PID control parameter switching logics are as follows: when theta isaveThe value after filtering by a first-order low-pass filter is greater than 20 DEG or the value after filtering is greater than 10 DEG and WaveAfter the speed is more than 9% of the rated rotating speed, the variable pitch parameter is formed by PIDslowSwitch to PIDfastI.e. the pitch parameters are switched from floating platform motion control to rotational speed control and from PIDfastSwitch back to PIDslowThe condition is that when the requirement is not met and the preset time is delayed, the rotating speed control is switched back to the floating platform motion control, and the stable transition of the rotating speed control and the floating platform motion control is realized through the switching of two sets of PID control parameters, so that the negative damping motion of the floating platform can be ensured not to be excited, and the fluctuation of the rotating speed of the impeller can be effectively controlled.
Further, the control logic of the pitch controller is that the difference value between the measured rotating speed and the rotating speed set value is sent to the PID controller after a series of filtering and a pitch instruction value is output.
Further, the thetaaveThe mean value theta of the blade angles of the impellers 1 and 2 is collected by a main control system of the unitmean1、θmean2And carrying out weighted average processing to obtain the average value of the variable pitch angles of the two impellers.
Further, the WaveThe method is a speed average value obtained by carrying out weighted average processing on the measured rotating speed values of the generators of the impellers 1 and 2 collected by a main control system of the unit.
Further, the first order transfer function of the first order low pass filter is:

where T is the filter time constant and s is the Laplace operator.
Compared with the prior art, the invention has the following advantages and beneficial effects:
1. the decoupling method is applied to the floating double-impeller wind turbine generator, so that the control of the rotating speed of the impeller under high wind speed and large turbulence working condition is ensured, and the floating platform is not excited and moves stably.
2. Due to PIDfastThe method is mainly used for inhibiting the floating platform from moving, and the low-frequency load of the tower is reduced on the contrary to the stable pitch variation for the rotating speed control.
3. The decoupling method of the invention gives consideration to both rotating speed control and floating platform motion control, and obviously attenuates low-frequency fatigue load of the mooring system.

Detailed Description
The present invention will be further described with reference to the following specific examples.
When the floating wind turbine generator set operates above the rated wind speed, particularly near the rated wind speed, the thrust of an impeller of the floating wind turbine generator set reaches a peak value, the thrust is reduced along with the increase of the wind speed, and the partial derivative of the thrust to the wind speed is negative, namely the aerodynamic damping is negative; the absolute value of the negative damping is the largest near the rated wind speed, and the absolute value of the negative damping is reduced along with the increase of the wind speed, so that the floating platform is easy to be unstable near the rated wind speed, and if the pitch variation action is coupled with the movement of the floating platform at the moment, the fluctuation of the pitching direction of the floating platform is intensified. When the wind speed is increased to be close to the cut-out wind speed, the pneumatic damping is close to a zero value or a positive value, the floating platform moves to be stable, and the variable pitch controller can be mainly used for controlling the fluctuation of the rotating speed of the impeller.
The first-order asymmetric wind speed field can be linearized, the blade angle is closely related to the wind speed change, namely the corresponding blade angle can be found in the pitch action field at any instantaneous wind speed, so the change of the pitch angle can also approximately describe the change of the wind speed.
In this embodiment, the application object is a floating type double-impeller wind turbine generator, as shown in fig. 1, the generator specifically includes two fans sharing a floating platform through a Y-shaped tower, the two fans are respectively installed on two end portions of the Y-shaped tower through respective yaw driving systems, the bottom of the Y-shaped tower is fixed on the floating platform, and the rotating directions of the impellers of the two fans are opposite to each other, so as to offset the centrifugal force of the two fans.
For two fans sharing one floating platform, the decoupling method for controlling the rotating speed of the floating type double-impeller wind turbine generator and the motion of the floating platform provided by the embodiment sets theta for coordinating the actions of the blades of the two impellers to jointly inhibit the motion of the floating platformaveIs the mean value theta of blade angles of the impeller 1mean1And mean value theta of blade angle of impeller 2mean2Is characterized by a weighted average of the wind speeds at the centers of the respective hubs of the two impellers, and W is setaveFor the impeller 1 generator speed W1And impeller 2 generator speed W2And configuring two sets of PID control parameters for a variable pitch controller of the unit, wherein the two sets of PID control parameters are respectively PIDfastParameters and PIDslowParameter, wherein PIDfastThe parameter being for controlling speed fluctuations, PIDslowThe parameters are used for inhibiting the floating platform to enable the bandwidth of the variable pitch controller to be smaller than the moving frequency of the floating platform, and the two sets of PID control parameter switching logics are as follows: when theta isaveThe value after filtering by a first-order low-pass filter is greater than 20 DEG or the value after filtering is greater than 10 DEG and WaveAfter the speed is more than 9% of the rated rotating speed, the variable pitch parameter is formed by PIDslowSwitch to PIDfastI.e. the pitch parameters are switched from floating platform motion control to rotational speed control and from PIDfastSwitch back to PIDslowIf the above requirement is not satisfied and the delay is 5s, the control of the rotation speed is switched back to the control of the floating platform movement. Wherein, the first order transfer function of the first order low-pass filter is:
Figure BDA0002665011830000041
where T is the filter time constant and s is the Laplace operator.
The decoupling method realizes the stable transition of the rotating speed control and the floating platform motion control by switching two sets of PID control parameters, ensures that the negative damping motion of the floating platform can not be excited, and can effectively control the fluctuation of the rotating speed of the impeller.
FIG. 2 shows a logic block diagram of decoupling of rotational speed control (also called pitch control) and floating platform motion control.
