A system and method for configuring an intelligent electronic device (IED) from a plurality of IEDs connected in a communication network of a substation with a computing system includes a computing system communicatively connected in the communication network of the substation for transmitting a configuration of at least one application function to the IED for operating an electrical equipment in the substation. The method for configuring the IED comprises using a virtual model of the IED to generate the IED configurations through a simulation that involves a sequence prediction technique. The sequence prediction technique facilitates generating a sequence of functions arranged in an order and sequentially determining connections between at least one input and at least one output of the one or more functions that comprises the application function. The generated sequence of functions and sequence of connections constitute the IED configuration corresponding to a given application function.

Method for configuring an intelligent electronic device

A method for detecting a fault in an intelligent electronic device that includes components uses a Bayesian network. The method includes detecting a failure event in the components, obtaining a first list of cause of failures in the component using a fault tree model, computing probability of the cause of failures to obtain a second list of probable causes of failure by monitoring of information about the elements identified in the first list, identifying a root cause of failure associated with the element comprised in the component using the Bayesian network based on the second list, and initiating a function. The function may be one of restarting the element having the root cause of failure, a filtering operation for input data provided to that element; and providing an alert in the human machine interface associated with the intelligent electronic device.

A method and a system for power management for a plant electrical network are provided. The power management system over a plant-wide communication network includes both concepts of hierarchical level and distributed level power management using multiple controllers. At least one controller in the power management system is configured for power management in a first local process area within the plant electrical network and is capable to communicate with at least a second controller configured for power management in a second local process area within the plant electrical network over the communication network.

Method and system for power management

A method and system for distributed power management with individual IEDs in a substation are disclosed. An exemplary technique can include providing multiple IEDs in a power network in the substation and integrating an intrinsic load shedding function in each IED. The technique can include identifying a power imbalance state at an individual IED and load shedding the individual IED using an intrinsic load shedding function when a power imbalance state is identified in a coordinated manner to achieve distributed power management in the substation.
