Connection Information
| Option | Description |
|---|---|
| ID Name |
Uniquely identifies the equipment item. The program automatically assigns a name, but you can change it, if needed. The name can be up to 16 characters long. For batteries, the program automatically assigns the names BAT-1, BAT-2, BAT-3, and so on. |
| To Bus | This is the ID name of the bus to which the equipment is connected. The base kV of the bus is indicated on the right. |
Specifications Tab
| Option | Description |
|---|---|
| Total Rated kV | This is the total voltage rating of the battery string. |
| Charging Multiplier | This is multiplier for the battery voltage reflecting the charge condition. For example, a fully charged battery could have 1.05 and a slightly drained battery may have 0.95 as the charging multiplier. |
| Total R | This is the internal resistance of the battery string in ohms. |
| Rated Amps | The rated amperes of the battery or battery string. Most batteries typically have the ampere-hour rating on an 8-hour basis. The nominal amp rating is the ampere-hour divided by 8 for such batteries. If the battery rating in ampere-hours is given at a different discharge duration, then divide by the stated number. |
Note: Batteries are modeled as a straight Thevenin voltage source behind a resistance. They HOLD voltage behind an internal resistance like a swing bus. Batteries have the ability to be the single source that enables a system to enter power flow and solve the system.
