Abstract

There is provided mechanisms for monitoring substation equipment. A method is performed by a SCADA system. The method comprises obtaining data / signal values of parameters monitored in the substation equipment. The method comprises associating each data / signal value with at least one attention indicator. The method comprises determining one attention indicator value for each of the attention indicators by processing those data / signal values that are associated with the respective attention indicators. All attention indicators for all monitored parameters have one and the same nominal attention indicator value acting as a threshold for abnormal behavior of the substation equipment. The method comprises providing an alert indication to a human machine interface (HMI) when at least one of the attention indicator values is above the nominal attention indicator value.

Description

technical field [0001] Embodiments presented herein relate to a method, supervisory control and data acquisition (SCADA) system, computer program, and computer program product for monitoring substation equipment. Background technique [0002] Substation equipment (eg, transformers, circuit breakers, etc.) is traditionally monitored by dedicated hardware, software, and its own interfaces to provide results, warnings, and alarms to users. The general understanding is that data processing and analysis should be performed locally in the monitoring hardware, and results should be provided locally on a human-machine interface (HMI) or remotely via a web interface. This leaves substation owners, operators, or those responsible for asset health with no choice but to integrate all monitoring results into one common interface or work with many different interfaces, which in practice leads to inefficiencies for such monitoring equipment Not even available. [0003] Since there may be...
