FLISR software for automation of electricity distribution networks.
ActionWise is a SCADA/ADMS application software, including topological processor, state estimator, power flow and a set of advanced functions for the management of the distribution network, such as the FLISR function (Fault Location, Isolation and Restoration of Service).
Grid modeling with ActionWise
The information needed for modeling the electrical network can be appropriated in two different ways, through the ActionWise Toolkit, which is a topology editor for the electrical network, or through an importer that reads data from the utility’s planning module. Some systems such as Anarede, Anafas, BDGD Aneel, among others, already have the importer ready.
The SCADA module acquires data from the field and sends orders to the field, isolating the problem and restoring service. This module can communicate directly with circuit breakers, reclosers and switches, or it can talk to the SCADA utility, which acts as a gateway for the FLISR function.
The SCADA database and screens are automatically generated. Thus, the controlled loops are generated from the topological network generated by the Toolkit.

Highlights
Electric grid modeling allows for the integrated and complete representation of any topology, involving all system segments, making it ideal for the analysis of smart grids, where measurement, monitoring, control, automation and generation points are present in any voltage level.
The software runs both in stand-alone mode, communicating with the field, and in the extension mode of the existing SCADA. In either of these modes, the solution can be deployed either in the control center (COS) or in a substation or a regional office.
Possibility of manual configuration of the database or integration with geographic information systems (GIS or BDGD) to obtain topological and electrical data from the network
Obtaining real-time analogue and digital data from network equipment and sending commands to them. Possibility of obtaining data directly from the equipment or integration with the existing SCADA system at the utility.
Periodic execution of a state estimation algorithm, which allows the determination in near real time of several magnitudes of the electrical system. In addition, if a fault occurs in the network, the solution uses the estimation of the network state at an instant before and close to the moment of the fault, which increases the precision of the calculations performed.
Modified genetic algorithm to obtain the sequence of maneuvers to be performed to isolate the defect and restore the energy supply to healthy stretches of the network.
Graphical interface with simplified schematic diagrams for electrical system operation.
After system parameterization, ActionWise can operate in three different ways:
The software does not communicate with the field, and data are simulated from historical data of the modeled network. In this case, to verify the behavior of the FLISR function, it is possible to simulate faults through the SCADA HMI and check how the system will be reset.
The software starts to communicate with the field and implements the FLISR function, that is, from the data acquired from the field in real time it locates faults in opening switches or circuit breakers of feeders in the electrical network, and proposes/executes actions to isolate the fault and restore the system by maximizing quality indicators.
It is a special situation of the real-time mode where the software acquires real data from the field and informs you what it would do to recover occurrences, without actually doing it. This mode is used when commissioning the system, as the faults are real and the software only informs, through the HMI, which maneuvers would be performed.

New features
Overload and under/overvoltage problems detected in the electrical network:
Isolated blocks:
Detection of faults and interruptions in sections not monitored by the system:
Prevention of subsequent overload and voltage:
Intelligent management of distribution circuits:
Identification of cases of lack of coordination of protection settings in the network:
Overload and under/overvoltage problems detected in the electrical network:
To detect such situations in the electrical network, ActionWise periodically runs a state estimation algorithm. This algorithm uses current and voltage data sent by field equipment to estimate these electrical quantities at other points in the network. With this estimation in hand, the software compares the calculated values with the nominal capacities of each equipment and section, thus detecting cases of overload and under/overvoltage.
Isolated blocks:
Periodically, ActionWise checks if there are isolated load blocks in the network. If so, it suggests to the operator a sequence of maneuvers to restore the energy supply to that block.
Detection of faults and interruptions in sections not monitored by the system:
Example: actuation of a bus breaker in the substation not monitored by ActionWise.
Prevention of subsequent overload and voltage:
The sequence of maneuvers generated by ActionWise respects the operational current and voltage limits of the equipment and the network, ensuring that there are no subsequent overload and voltage problems.
Intelligent management of distribution circuits:
To obtain the sequence of operations, the algorithm does not consider only the circuits directly neighboring the circuit where the fault occurred, but all monitored circuits. In this way, it is possible to transfer load initially from a directly neighboring circuit to the “neighbor neighbor”, so that the directly neighboring circuit has greater capacity to receive load from the circuit where the fault occurred.
Identification of cases of lack of coordination of protection settings in the network:
If the fault is detected by two devices in series, but the action has occurred in the wrong way in the upstream equipment, ActionWise identifies this problem and performs the maneuvers considering the problem of lack of coordination.
