The following describes the options available when creating a contingency element of type Phase Shifter. Contingency elements are created from the Contingency Element Dialog, and additional details of how to create contingency elements can be found here.

 

Action Settings

Set To

The Set To action will set the middle of the regulation range of the selected phase shifter to the specified Amount. The middle of the regulation range is calculated by taking the average of the Regulation Minimum MW Flow and Regulation Maximum MW Flow. The middle of the regulation can be set in Percent or MW. If the middle of the regulation range is set in Percent, the middle of the range is set to the specified percent of the contingency reference state middle of the regulation range. If the middle of the regulation range is set in MW, then the middle of the regulation range is set to the specified amount. Regardless of the method used to set the middle of the regulation range, the regulation range will remain the same, but the Regulation Minimum MW Flow and Regulation Maximum MW Flow will be adjusted so that the specified middle of the regulation range is met.

Added in version 20

By selecting the Degrees option the phase angle of the phase shifter can be set to the specified Amount. Automatic control for this phase shifter will be disabled so that it will not be adjusted by any automatic control schemes.

Change By

The Change By action will change the middle of the regulation range of the selected phase shifter by the specified Amount. The middle of the regulation range is calculated by taking the average of the Regulation Minimum MW Flow and the Regulation Maximum MW Flow. The middle of the regulation range can be changed in Percent or MW. When the middle of the regulation range is changed in Percent, the change is based on the specified percent of the contingency reference state middle of the regulation range. When the middle of the regulation range is changed in MW, the middle of the present regulation range is changed by the specified amount. Regardless of the method used to change the middle of the regulation range, the regulation range will remain the same, but the Regulation Minimum MW Flow and Regulation Maximum MW Flow will be adjusted so that the specified middle of the regulation range is met.

Added in version 20

By selecting the Degrees option the phase angle of the phase shifter will be changed from its present value by the specified Amount. Automatic control for this phase shifter will be disabled so that it will not be adjusted by any automatic control schemes.
