Contingency Options: Switched Shunt Response
The Switched Shunt Post-Contingency Response display can be opened from the Modeling group of the Contingency Analysis dialog Options page. This display provicccccbgtflgdes a specialized switched shunt display with specific fields used for setting the post-contingency response of individual switched shunts. These fields allow you to general change three things in the post-contingency power flow solution: control mode, Regulation Values, and Max/Min Mvar outputs. Details of these fields are as follows.
Field |
Description |
CTGShuntMode |
Specify a value to which ShuntMode should be changed during the post contingency power flow solution. Options are the same as for ShuntMode field (Fixed, Discrete, Continuous, Bus Shunt, or SVC) but the value may also be set to Default indicating that it should not change the ShuntMode. |
CTGRegUse |
If this value is set to YES, then during the post contingency power flow solution the RegHigh and RegLow of the switched shunt will be changed to match CTGRegHigh and CTGRegLow. If the existing shunt is set to use the RegTargetHigh value then the target values will be changed such that RegTarget = CTGRegLow RegTargetHigh = CTGRegHigh Otherwise, the target value will be changed to the middle of the new range with a value of RegTarget = (CTGRegLow + CTGRegHigh)/2 |
CTGRegLow |
Use as described in CTGRegUse above |
CTGRegHigh |
Use as described in CTGRegUse above |
CTGMvarUse |
This is only used for switched shunts that are one of the following
If this value is set to YES, then during the post-contingency power flow solution, fields associated with the shunt blocks and use of continuous element of the switched shunt will be modified to achieve the CTGMvarMin and CTGMvarMax values specified. |
CTGMvarMin |
Used as described in CTGMvarUse above |
CTGMvarMax |
Used as described in CTGMvarUse above |
