Please see Generator Reactive Power Capability Curve for details. The generator reactive capability can be defined using the table that appears at the bottom of the dialog. Otherwise, the fixed values given in the Min Mvar Output and Max Mvar Output fields are used. If checked, the generator's reactive power limits are specified using a reactive capability curve that prescribes the dependence of the generator's reactive power limits on its real power output. If a reactive limit is reached, the generator will no longer be able to maintain its voltage at the setpoint value, and its reactive power will then be held constant at the limit value. When the AVR field is checked, the generator will automatically change its reactive power output to maintain the desired terminal voltage within the specified reactive power range. Specify the minimum and maximum allowable reactive power output of the generator.ĭesignates whether or not the generator is available for automatic voltage regulation (AVR). You can manually change this value only if Available for AVR is not checked. The Voltage Control grouping is used to show/change values associated with controlling the voltage/reactive power output of the generator.Ĭurrent reactive power output of the generator. The implicit assumption in calculating this field's value is that the incremental change in generation will be absorbed by the system "slack bus." This field cannot be changed. This information is useful in determining the economic dispatch for the generation. Shows how the losses for an area will change for an incremental increase in the generation at the bus. When you open a case using the PTI Raw Data Format, this field is initialized to the per unit MVA rating of the generator, since participation factor information is not stored in the PTI format. The participation factor is used to determine how the real power output of the generator changes in response to demand when the generator is available for AGC and the area is on participation factor control. If this box is checked and a generator is violating a real power limit, the generator's MW output is immediately changed.
If checked, the minimum and maximum MW limits are enforced for the generator, provided the Enforce Generator MW Limits field is also checked on the Limits Tab of the Simulator Options Dialog. You could then place the generator back on AGC control by using this dialog. A generator is also placed on "manual" control any time you manually change its output. However, there are times when you would like to control the generator output manually (such as if you are using the generator to remove a line limit violation), in which case you should leave this box unchecked.
Simulator will not let the MW output go below its minimum value or above its maximum value if the Enforce MW Limits option is exercised.ĭetermines whether or not the generator is available for automatic generation control (AGC). Minimum and maximum real power output limits for the generator. If the generator either has a status of OPEN or if the bus is disconnected, then MW Output will show 0.00, but the MW Setpoint will show the value of MW that is stored with generator and if the generator does get reconnected that is the MW it will be at.
If a generator is presently online this will show the same value as the MW Output. The Power Control grouping fields are used to show/change the values associated with the real power output of the generator.Ĭurrent real power output of the generator. Generator Information: Power and Voltage Control
