CERN is a major electricity consumer. In 2018 it consumed 1.25 TWh, 1/3 the consumption of Geneva. Monitoring of this consumption is crucial for operational reasons but also for raising awareness of the users regarding energy utilization. This monitoring is done via a system, developed internally and is quite popular within the CERN community therefore to accommodate the increasing requirements, a migration is underway that utilizes the latest technologies for data modeling and processing.

CERN is a major electricity consumer. In 2018 it consumed 1.25 TWh, 1/3 the consumption of Geneva. Monitoring of this consumption is crucial for operational reasons but also for raising awareness of the users regarding energy utilization. This monitoring is done via a system, developed internally and is quite popular within the CERN community therefore to accommodate the increasing requirements, a migration is underway that utilizes the latest technologies for data modeling and processing. We present the architecture of the new energy monitoring system with an emphasis on the data modeling, versioning and the use of graphs to store and process the model of the electrical network for the energy calculations Weniger anzeigen

The monitoring and control of the CERN electrical network consists of a great variety of devices and software: it spans from low level acquisition devices to high level data concentrators, supervision systems as well as power network simulation tools. The main issue faced nowadays for the engineering of such a large and heterogeneous system, including more than 20,000 devices and 200,000 tags, is that all devices and software have their own data engineering tool while a great part of the… Mehr anzeigen

The monitoring and control of the CERN electrical network consists of a great variety of devices and software: it spans from low level acquisition devices to high level data concentrators, supervision systems as well as power network simulation tools. The main issue faced nowadays for the engineering of such a large and heterogeneous system, including more than 20,000 devices and 200,000 tags, is that all devices and software have their own data engineering tool while a great part of the configuration data has to be shared between two or more devices: the same data needs to be entered manually to the different tools leading to duplication of effort and many inconsistencies. This paper presents a web-based application called ENSDM, mainly based on open technologies, aiming at centralizing all the data needed to engineer the monitoring and control infrastructure into a single database from which the configuration of the various devices is extracted automatically. Such approach allows the user to enter the information only once and guarantee the consistency of the data across the entire system. The paper also demonstrates the configuration workflow of different parts of the system, namely the remote terminal units, devices, the global supervision system (SCADA) and the power network simulation tools Weniger anzeigen
