摘要
针对目前风电机组控制性能综合评估时缺乏量化标准与评估方法的问题,提出了一种基于子空间线性二次高斯(LQG)的控制性能量化评估方法,利用子空间矩阵法求解出评估权衡曲线,确立了风电机组 LQG 控制性能基准与评估指标.以增加塔架阻尼减载控制改造的机组作为评估算例,采用 2种数据处理策略进行改造前、后变桨控制性能的多变量综合量化评估.结果表明:2 种数据处理策略均可得到准确有效的量化评估结果,所提评估方法可以实现对控制策略优化效果的综合量化评价.
Abstract
Aiming at the lack of quantitative standards and assessment methods in the current comprehensive assessment of wind turbine control performance,a quantitative assessment method of control performance based on subspace linear quadratic Gaussian(LQG)is proposed.The subspace matrix method is used to solve the assessment trade-off curve,and the benchmark and assessment index of LQG control performance of wind turbines are established.By taking the turbine retrofitted by adding tower damping and load shedding control as an example of the assessment,the multivariate comprehensive quantitative assessment of pitch control performance before and after retrofitting is carried out by using two kinds of data processing strategies.The results show that,both data processing strategies can obtain accurate and effective quantitative evaluation results,and the proposed evaluation method can realize the comprehensive quantitative evaluation of the optimization effect of control strategies.
