Document Type and Number:
Japanese Patent JP7232936
Kind Code:
B2
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 parameter 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.
