Embodiment 1
[0065] Such as figure 1 , 3 As shown in and 4, the present embodiment provides a method for filtering wind power curve scattered points, including the following steps:
[0066] Step S001, acquire the SCADA data set M01 data packet of the target wind turbine by using the SCADA system.
[0067] Step S002, input the M01 data packet into the data filter, and set the power threshold h=0.1 through the filter, compare and screen all the power data in the M01 data packet, and obtain power less than or equal to 0.1 after screening The data packet M011 and the data packet M012 with a power greater than 0.1; here, it should be noted that the data is filtered according to this method, and it can be considered that the power critical value is set for different fans or due to different actual target data requirements. The specific value of the value h, and one or more can be set, and the M01 data packet is divided into a plurality of data packets M011, M012...M01n divided by the power thr...
Embodiment 2
[0072] In order to further accurately realize the processing of data, on the basis of embodiment 1, the data type in the SCADA data set M01 data packet in the step S001 corresponds to the initialization parameter type in the power curve tracker described in the step S003; The initialization parameters include wind speed upper boundary position value, wind speed lower boundary position value, power window size value, wind speed standard deviation threshold, upper and lower boundary width threshold, allowable upper and lower bounds of front and rear window tracking point difference, window tracking point offset value , rated power initial wind speed value and rated power floating value. It is worth noting that: since the SCADA system is a computer-based DCS and electric power automation monitoring system; Process control and many other fields. Therefore, the target data types that need to be collected in the data collection of corresponding fields or in different purposes are p...
Embodiment 3
[0074] In order to further refine the present invention, on the basis of any of the above-mentioned embodiments, further combine figure 2 As shown, in this embodiment, the process for the first filtering unit G1 to obtain the update data packet M011a through the data packet M011 in the above step S003 includes the following steps:
[0075] Step S0031, determining the starting point of the power curve: selecting the average value of all wind speed data in the power range 1-10;
[0076] Step S0032, filtering invalid data: select and delete all data whose power is less than 5 and whose wind speed is greater than the starting point of the power curve, to obtain an update data package M011a. The first filtering unit G1 is one of the computing modules in the power curve tracker, and the computing rules programmed in the computing module can be implemented by means including but not limited to custom logic operations. It is a prior art for those skilled in the art to realize the se...
