摘要
梯级水电站群泄洪调度中,多源测控数据噪声大、异常识别不足,易引发误操作,亟需以闸门操作原则为核心的高精度稳定智能防误策略。因此,研究提出一种融合电子测量与改进滤波算法的方法,利用工业相机等仪器构建高精度监测体系,结合改进滤波算法实现非线性补偿与动态估计,并在冗余控制器与边缘计算终端上构建闭环控制平台,以保障调度指令与闸门操作规程的一致性。实验结果表明,该方法在水位预测中最大误差仅为1.2 cm。在噪声水平提升至20 dB时,信噪比仍保持12.1 dB。误操作率仅为7.52%,较基线方法下降16.32%,指令校核响应时间缩短至135.6 ms。在调度频率为每分钟10条时,故障检出率和安全闭锁触发率分别达到91.84%和95.64%。以上结果表明,该方法在精度、实时性与鲁棒性方面表现突出,为梯级水电站群泄洪闸门的安全高效运行提供了可靠技术支撑。
In flood discharge operations at cascade hydropower stations,multi-source measurement and control data suffers from high noise levels and insufficient anomaly recognition,which can easily lead to misoperations.Highly accurate and stable intelligent error prevention strategies are urgently needed.Therefore,this study proposes a method that integrates electronic measurement with an improved filtering algorithm.This method utilizes industrial cameras and other instruments to construct a high-precision monitoring system.The improved filtering algorithm is combined with nonlinear compensation and dynamic estimation,and closed-loop control is implemented across redundant controllers and edge computing terminals.Experimental results demonstrate that this method achieves a maximum error of only 1.2 cm in water level prediction.Even when the noise level rises to 20 dB,the signal-to-noise ratio remains at 12.1 dB.The misoperation rate is only 7.52%,a 16.32%decrease compared to the baseline method,and the command verification response time is shortened to 135.6 ms.At a dispatch frequency of 10 commands per minute,the fault detection rate and safety lockout triggering rate reach 91.84%and 95.64%,respectively.These results demonstrate that this method demonstrates outstanding accuracy,real-time performance,and robustness,providing reliable technical support for the safe and efficient operation of flood discharge gates at cascade hydropower stations.
