Number of buses limit for power world simulator 19
Multiple shunts at the same bus may have a control mode other than Fixed or Bus Shunt (Fixed). Information about these options can be found in the SVC Control Mode. SVC control mode is intended to simulate controlled VAR devices with one continuous or discrete element that can control up to 8 fixed shunts (these shunts do not have to have a control mode that is fixed but they are treated as fixed as long as they are being controlled by an SVC). The reason for the differentiation of the Bus Shunt versus normal Fixed control is that the Bus Shunt control type is intended to identify the difference between a bus shunt and a switched shunt that MAY have controllability, but is currently turned of off control by being set to a Fixed value. Bus shunts that are represented as switched shunt objects on Bus Shunt control, however, are mathematically exactly the same and can be turned on or off. The difference is that bus shunts stored directly with the bus cannot be turned on and off in the load flow rather they are always included in the load flow solution. This is analogous to the shunt MW and MVAR values that can also be stored at the bus level. Note the additional control mode called Bus Shunt (Fixed). Note: Automatic control of switched shunts is disabled if the regulation high value is not greater than the low value they should not be equal unless in continuous mode. The Auto Control option for the switched shunt must be true.

If the Control Mode is SVC, the case-wide option Disable SVC Control also found on the Power Flow Solution tab of the Simulator Options dialog must not be checked.

The Control Mode field must be set to either Discrete, Continuous, or SVC and the shunt must not be controlled by an SVC.However, for a switched shunt to be used for automatic control, the following fields must be set correctly: Parameters (page on the Switched Shunt Information dialog)ĭetermines whether the switched shunt has a fixed value, or whether the amount of reactive power supplied by the device changes either in discrete steps or continuously in order to maintain its regulated value within the regulation range specified in the Control Regulation Settings. They can also be set from the Switched Shunt Display. Switched shunt control parameters can be set from the Switched Shunt Information dialog in either Edit mode or Run mode.
