风电功率斜坡事件是指风电功率在短时间间隔内发生大幅度波动，将严重影响电网系统的安全稳定运行。为了维持电网系统的稳定运行，风电场功率斜坡检测是极其必要的。因此，如何提高风电场功率斜坡检测的准确性是一个值得研究的问题。现有的风电场斜坡检测算法没有考虑斜坡端点的准确性。针对风电爬坡段的端点准确性问题，提出了一种基于斜坡点校正的风电爬坡检测算法RPCRD（ramp point correct climbing detection），首次考虑了风电爬坡点的检测准确性。该算法提出了爬坡段合并方法解决断裂问题，提出了爬坡点选择评分机制，寻找最符合爬坡特性的两个极值点，并对风电爬坡段两端的爬坡点进行了修正。
Wind power ramp event refers to the large fluctuation of wind power in a short time interval, which will seriously affect the safe and stable operation of power grid system. In order to maintain the stable operation of power grid system, wind power ramp detection is extremely necessary. Therefore, how to improve the accuracy of wind power ramp detection is a problem worthy of study. In the existing wind power ramp detection algorithms, the accuracy of the ramp endpoint is not considered. Aiming at the problem of end-point accuracy in climbing section, this work proposes a wind power climbing detection algorithm RPCRD (ramp point correct climbing detection) based on ramp point correction, which considers the detection accuracy of wind power climbing point for the first time. In this algorithm, a merging method of climbing sections is proposed to solve the fracture problem, and a scoring mechanism for selecting climbing points is proposed to find the two extreme points that most conform to the climbing characteristics, and the climbing points at both ends of the climbing section of wind power are modified.
