Distribution automation features / functionality | Function enabled | Description |
---|---|---|
Fault location, isolation and service restoration (FLISR) | Yes | Avista is implementing an Application that is called Fault Detection Isolation & Restoration (FDIR). FDIR is initiated once a breaker recloser locks open. Once the device is opened up, the application begins an upstream isolation, trying to restore energy from the opened device out to the location of the fault. Once that is complete, the system will attempt to restore energy to the customers downstream from the fault utilizing adjacent feeders. This process is automated and will not require intervention from a dispatcher. |
Voltage optimization | Yes | The system will manage the power factor keeping it within a specified range, and ensure that measured line voltages and calculated end of line voltages are within in the allowable range. The system will use a combination of switchable capacitor banks along the distribution line as well as a voltage regulator in the substation. The DA switching devices installed have voltage and current sensing capabilities and will provide the feedback to the system to monitor performance. |
Feeder peak load management | Yes | This application does not have a specific Peak Load Management application. However, the realtime power flows will allow operators and engineers to better manage peak demands and transfer loads to adjacent sources. |
Microgrids | No | |
Other functions | No | The DA system will include a distributed generation application that will allow the simulation calculation engine to take in the impacts of customer generation as well as other distributed energy resources. |
* In some circumstances, costs are incurred before devices are installed resulting in a reported cost where the quantity is zero.
* All dollar figures are the total cost, which is the sum of the federal investment and cost share of the recipient (the recipient cost share must be at least 50% of the total overall project cost).
** In some cases the number of entities reporting is greater than the total number of projects funded by the Recovery Act because some projects have multiple sub-projects that report data. View list of sub-projects.
