Monitoring Systems for Secondary Substations | TD World

Project PlanningMonitoring SystemsSystem InstallationCommunication and SecurityContinuous Monitoring and DataSystem OutlookAcknowledgementSystem planning started in 2011 with the objective to collect all data. As many relevant signals and measurements as possible were collected, although it remained unclear how exactly all the data could be used to benefit the customer and Ellevio. Therefore, Ellevio decided to divide the monitoring of medium-voltage/low-voltage (MV/LV) substations into different functional levels. The basic level describes the situation today in Stockholm. Most equipment is operated locally with only a basic remote communications link that is a combined sum alarm function for the secondary substations. A sum alarm consists of five to 15 unique alarms that can be caused by, for example, a high transformer temperature or a tripped circuit breaker. Any of these alarms triggers a sum alarm through the underground control cable network to the source primary substation and, from there, through the supervisory control and data acquisition (SCADA) system to the network operations center. The high monitoring...Get price
