Leakage detection and leakage location in supply networks

Abstract

The invention relates to a method and device for leakage detection and leakage location in an area of a supply network (e.g. water supply, gas supply or district heating network), wherein measurement values of sensors of the supply network are statistically analysed for the presence of leakages using robust regression methods. The false alarm rate (type 2 error) is in particular minimised.

Description

technical field [0001] The invention relates to a method, a use and a device for detecting and locating leaks in the region of a supply network. Background technique [0002] In the 21st century, drinking water is among the most important items during this period. However, there are sometimes significant water losses in the water distribution network. [0003] The custody of such items places great demands on leak identification and leak location in water networks. The method of identifying water loss by means of a mass balance, in which all injections and especially water losses of all individual water consumers are measured, exceeds feasible limits in terms of inputs. In addition, time-accurate consumption measurements and consumption logging of all user data are legally required. [0004] Leaks in water networks are traditionally detected only by measuring the overall water flow into the network at certain times, for example, during the time period between 2 and 4 o'cl...
