Detailed Description
The following detailed description of the embodiments of the disclosure refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
It should be noted that all actions of acquiring signals, information or data in the present disclosure are performed under the premise of complying with the corresponding data protection regulation policy of the country of the location and obtaining the authorization given by the owner of the corresponding device.
Firstly, an application scenario of the method is introduced, the method is applied to a scenario of estimating wake loss of a wind turbine generator, and in the early stage of building a wind farm, the wake effect of the wind turbine generator of the wind farm is estimated to be used for measuring and calculating the generated energy of the wind farm. In the prior art, a target wind turbine generator is selected from a target wind power plant, the target wind turbine generator comprises an upstream wind turbine generator and a downstream wind turbine generator, speed loss data of the target wind turbine generator is obtained through a cabin radar, and generating capacity loss, namely wake loss, is calculated according to the speed loss data.
However, the inventor finds that, because the evolution of the wake flow field is very complex and is influenced by the thermal stability and turbulence of the atmosphere, the accuracy of the obtained speed loss data is not high by measuring the speed of the air flow passing through the wind turbine generator by the nacelle radar, and the speed loss data needs to be converted into the wake loss data, so that a user cannot visually see the wake loss data.
Therefore, the present disclosure provides a method, an apparatus, a storage medium, and an electronic device for estimating wake loss, where the method obtains a wind direction and a wind angle of a target wind turbine; the target wind turbine generator set comprises an upstream wind turbine generator set and a downstream wind turbine generator set; under the condition that the wind direction is a preset wind direction and the wind angle of the target wind turbine generator is smaller than or equal to a preset angle, acquiring a plurality of first output powers corresponding to the upstream wind turbine generator at the current wind speed; acquiring a plurality of second output powers corresponding to the downstream wind turbine generator set at the current wind speed; and calculating the wake flow loss of the target wind turbine generator according to the plurality of first output powers and the plurality of second output powers. Therefore, the wake loss is obtained through calculation of the actual operation data of the target wind turbine generator, the stability of the actual operation data is good, the evaluation result is more accurate, and the evaluation efficiency of the wake loss is improved.
Fig. 1 is a flow chart illustrating a method of wake loss assessment, according to an exemplary embodiment, including the following steps.
Step 101, acquiring the wind direction and the wind angle of a target wind turbine generator.
The target wind turbine generator set comprises an upstream wind turbine generator set and a downstream wind turbine generator set.
For example, a target wind turbine is selected from a target wind farm, the target wind farm may be a large offshore wind farm or a large land wind farm, an upstream wind turbine is determined in the target wind farm, for example, the upstream wind turbine may be a first-row wind turbine of the target wind farm or a randomly selected wind turbine, and then a next-bit wind turbine behind the upstream wind turbine is selected as a downstream wind turbine.
It should be noted that the upstream and downstream wind turbines may be wind turbines of the same type and both in a normal operation state.
102, under the condition that the wind direction is a preset wind direction and the pair of wind angles of the target wind turbine are smaller than or equal to a preset angle, acquiring a plurality of first output powers corresponding to the upstream wind turbine at the current wind speed; and acquiring a plurality of second output powers corresponding to the downstream wind turbine generator set at the current wind speed.
The wind direction and the wind speed data of the target wind turbine can be acquired from the engine room radar, and the engine room radar is used for accurately detecting the wind direction and the wind speed information in the front of the hub of the wind turbine. Acquiring the wind angle and the output power of a target wind turbine generator from an SCADA system; the SCADA (supervisory control and data acquisition) system comprises a supervisory control computer, a Remote Terminal Unit (RTU), a Programmable Logic Controller (PLC), a communication infrastructure and a human-machine interface (HMI), and can be used for acquiring and monitoring wind angle and output power data of a target wind turbine.
In some embodiments, it may be determined that the wind direction is a preset wind direction through wind direction data output by the nacelle radar, and whether the target wind turbine is facing the wind is determined through a wind facing angle output by the SCADA system, where the wind facing angle refers to an angle between the target wind turbine and a free incoming wind, and in one possible implementation, the target wind turbine is determined to be facing the wind in a case that the wind facing angle is less than or equal to the preset angle, for example, the preset angle may be 5 degrees. In the case of the target wind turbine group facing the wind, the wind speed data at that time may be obtained from the nacelle radar as the current wind speed, and then, the first output powers of the upstream wind turbine and the second output powers of the downstream wind turbine at the current wind speed are obtained from the SCADA system.
For example, the preset wind direction is a main wind direction of the target wind farm, that is, a main wind direction of a wind farm where the target wind turbine is located, and due to different geographical locations of the wind farms, the main wind direction is also different under an environmental influence, for example, the main wind direction may be a north wind, a south-east wind, a north-west wind, and the like, and the disclosure is not limited herein. And the main wind direction is the wind direction at a preset distance in front of the target wind turbine, the preset distance is 2.5D in front of the target wind turbine, D is the diameter of an impeller of the wind turbine, for example, D may be 180 meters, and the preset distance is 2.5 × 180=450 meters.
And 103, calculating the wake flow loss of the target wind turbine generator according to the plurality of first output powers and the plurality of second output powers.
In some embodiments, a first average power at a preset time may be calculated from the plurality of first output powers; calculating a second average power at the preset time according to the plurality of second output powers; and calculating the wake flow loss of the target wind turbine generator according to the first average power and the second average power.
For example, under the current wind speed, a plurality of first output powers of an upstream wind turbine are obtained, and since the time interval of the output wind speed is greater than the time interval of the output power, the same wind speed corresponds to the plurality of output powers, and the first average power can be obtained by averaging the plurality of first output powers; for example, the preset time is 10min, the wind speed is 1m/s at this time, 10 first output powers are correspondingly obtained, and the first average power at the wind speed of 1m/s is an average value of the 10 first output powers within 10min, which is not limited in the present disclosure. Similarly, the calculation process of the second average power is the same as the above process, and is not described herein again.
For example, when calculating the wake loss of the upstream and downstream wind turbine generators according to the first average power and the second average power, a difference between the first average power and the second average power may be used as a power loss value, and the wake loss may be obtained according to the power loss value and the first average power.
The wake loss is obtained according to the power loss value and the first average power, and a ratio of the power loss value and the first average power may be used as the wake loss.
For example, the wake loss may be given by the formula
Figure BDA0003733349970000071
Calculating the obtained percentage value, wherein P 1 Is the first average power, P 2 Is the second average power.
Therefore, the wake loss is obtained through calculation of the actual operation data of the target wind turbine generator, the stability of the actual operation data is good, the evaluation result is more accurate, and the evaluation efficiency of the wake loss is improved.
Considering that the wind speed is a variable quantity and can be different values, after the wind speeds with different values are obtained, the output power of the wind speed is determined, and the wake loss is calculated according to the output power, so that the wake loss data of the wind speed can be obtained by the method.
Furthermore, the method can also be used for counting the wake loss data of each wind turbine generator in different wind power plants in different wind directions or different wind speeds, and establishing a database according to the counted wake loss data for evaluating the wake loss, so that the database can be conveniently used as a reference material for newly-built wind power plant wake evaluation.
