摘　　要：为了研究双馈式抽水蓄能机组功率调节控制器参数对系统控制性能的影响,基于功率调节控制策略,采用正交试验设计方法分析功率调节控制器参数的敏感性。针对功率调节控制器中的4个参数(每个参数分别选取4个水平)进行正交设计,选取ITAE作为优化目标,筛选出稳定工况,通过极差分析,量化参数的敏感程度,区分出对系统控制性能产生影响的主要参数和次要参数。计算结果表明,较小的ITAE指标值代表系统动态响应品质高,误差更小且收敛速度更快。电流调节模块的比例系数对系统控制性能影响较大,而功率调节模块的积分系数、电流调节模块的积分系数功以及电流调节模块的比例系数对系统控制性能影响较小。功率调节控制器参数的敏感性分析,为双馈式抽水蓄能机组在电力系统中的可靠运行提供了理论依据。This paper aims to investigate the impact of power regulation controller parameters on the system's control performance of doubly-fed pumped storage units.Based on the power regulation control strategy,the paper employs an orthogonal experimental design to analyze the sensitivity of power regulation controller parameters.Four parameters in the power regulation controller(each parameter selected at 4 different levels)are subjected to orthogonal design.Integral of time-weighted absolute error(ITAE)is chosen as the optimization objective.Stable operating conditions are identified through range analysis.The sensitivity of parameters is quantified by range analysis to distinguish the major and minor parameters affecting the control performance of the system.The computational results demonstrate that a smaller ITAE value indicates higher dynamic response quality of the system,smaller errors,and faster convergence speed.The proportional coefficient of the current regulation module significantly influences the control performance of the system.However,the integral coefficient of the power regulation module,the integral coefficient of the current regulation module,and the proportional coefficient of the current regulation module have a relatively minor effect.The sensitivity analysis of power regulation controller parameters provides a theoretical foundation for the reliable operation of doubly-fed pumped storage units in the power system.
