Column Name | Description |
---|---|
Island Name | The name of the island as determined by one of the energization sources and the corresponding entry in the data model FEEDERS table. |
Status | The status of the power flow solution. These match the values reported in FLM. Typically, this can be one of: Solved, Suspect SCADA, Model error, Failed. |
Updated | The time the last information was written for this island. |
Solve Time | The time take to perform the state estimation, power flow solution, and SCADA load allocation. |
Supply Connections | Report how many energization source nodes feeder the island. |
Feeders | How many FID or MID nodes are present in the model. This is broadly related to the number of distribution feeders plus power transformers. The exact location of each of these nodes is determined during model design and project implementation. |
Buses | Number of connection points in the island. Each device (Transformer, switch, conductor, and so on) has a connection point at each end. |
Powerflow Iterations | Number of iterations of the power flow engine to converge on a solution. |
State Estimator Iterations | Number of iterations of the state estimator (capacitor status, network protector status, and/or regulating DERs) to converge on a solution. |
SCADA Iterations | Number of iterations of the SCADA load allocation engine to converge on a solution. |
Total Iterations | Sum of the previous three columns. |
Voltage Violations | Number of voltage violations (Low or High) detected by the power flow. |
Flow Violations | Number of thermal violations detected by the power flow. |
Transformers | Number of transformers in the islands. This figure typically excludes service transformers as they tend to be modeled as load points for the power flow. If, however, the load and DER behind the xfmr is dis-aggregated then the service transformers do get included in this count. This is implementation dependent and typically depends on the level of behind the meter DER penetration there is in a service territory. |
Shunts | Number of shunted devices (capacitors, SVCs, or reactors) in the island. |
Switches | Number of switchable devices (typically breakers, reclosers, load-break switches, non-load break switches, and fuses). |
Distributed Generators | Number of DER units (primary and behind the meter) that are in the island. |

SRC Index | The index handle of one of the energization sources feeding the island. |
