Presentation at NORDIWA 2018: “Is your data correct?”
12. June 2018 @ 10:30 - 12:00
Is your data correct? Validating and improving data collected in smart water networks
Within recent years, drinking water utilities have increased the installation of data collecting devices throughout their water distribution networks. The purpose of this data collection is to improve systems operation and to help secure drinking water safety and reliability even further. The growing data-dependency requires maintenance of high data integrity and monitoring of data validity. However, data validity and integrity testing is a lesser-described process step in research and water systems operation. As the collected data can suffer from errors that can severely reduce its value, it is of importance to quality assure the data automatically and in real time to avoid long periods with erroneous data. Most applications and studies within distribution system modelling assume flawless data and conduct analyses based on simple filtering of outliers and blank spaces. But, what if filtered outliers represent true extremes? What if time settings change or drift for some meters in the collected data? Can anomalies easily and reliably be replaced with estimated data? To improve the reliability and usability of the collected time series data, we propose a method for quality assurance and emulation of raw data in real time.
