- 摘要:
- 针对传统独立计量分区(DMA)小区漏损率异常检测方法依赖固定阈值或经验值的不足,提出了一种基于启发式高斯云变换(H-GCT)的漏损率阈值动态判定方法。通过高斯混合模型(GMM)拟合历史漏损率数据,结合高斯云模型量化概念含混度与交叠程度,实现正常与异常漏损率的划分,从而实现更科学的漏损率异常检测。选取L市30个DMA小区数据进行验证,结果表明,阈值漏损率范围为3.5%~9.0%,平均概念含混度为0.341 4,符合实际管网运行特征。该方法可为供水管网漏损监测与分区计量提供科学依据。
- Abstract:
- To address the shortcomings of traditional anomaly detection methods for leakage rates in district metered areas (DMA), which rely on fixed thresholds or empirical values, this paper proposes a dynamic threshold determination method based on heuristic Gaussian cloud transform (H-GCT). The method employs a Gaussian mixture model (GMM) to fit historical leakage rate data, and further combines it with a Gaussian cloud model to quantify the concept ambiguity and the degree of overlap, thereby enabling the classification of normal and abnormal leakage rates and achieving more scientific anomaly detection. Data from 30 DMA districts in city L were selected for validation. The results showed that the threshold leakage rates ranged from 3.5% to 9.0%, with an average concept ambiguity of 0.341 4, which was consistent with the actual operational characteristics of the water distribution network. The proposed method can provide a scientific basis for leakage monitoring and zonal metering in water supply pipeline networks.
