Timing Parameters
Name | Description | Unit | Variable = {Possible Values} | |
---|---|---|---|---|
Time units | Units applied to the programmed state transition operations | Ut = {s, ms, c} | ||
Second {s} | All operations Tn are in seconds | |||
Millisecond {ms} | All operations Tn are in milliseconds | |||
Cycle {c} | All operations Tn are in electrical cycles (setting the frequency is mandatory) | |||
General operation | Master switch that determines whether the programmed operations will occur upon triggering an acquisition | EnaGen = {0, 1} | ||
Disable {0} | Programmed operations are disabled | |||
Enable {1} | Programmed operations are enabled | |||
Steady-state condition | State of phase and ground breakers in steady-state; “colored” if the breaker is open and “grey” if the breaker is closed | EtatIniA = {0, 1} EtatIniB = {0, 1} EtatIniC = {0, 1} EtatIniN = {0, 1} | ||
Network frequency | Legacy. Should be set using the parameter "Base frequency". | Hz | Freq = { [45, 70] } | |
Model type | For each phase, determine whether the component acts as a switch or as a breaker | TypeA = {0, 1} TypeB = {0, 1} TypeC = {0, 1} TypeN = {0, 1} | ||
Breaker {0} | Once the time condition is met, the breaker waits for the current to cross the breaking capacity before changing its state | |||
Switch {1} | The state of the switch changes as soon as the time condition is met | |||
Enable | Enable/disable the state transition operation on the same line. | EnaT1 = {0, 1} EnaT2 = {0, 1} ... | ||
Disable {0} | Disable the state transition operation on the same line | |||
Enable {1} | Enable the state transition operation on the same line. If the line is enabled but no information is filled, the state transition operation is ignored. | |||
Time | Relative time (with respect to POW synchronization) when the command is sent to the breaker (or switch) to change state. There are four ways to input this time. Important notes:
| Refer to "Time units" parameter | T1 = {'string'} T2 = {'string'} ... | |
Fixed | (f: fixed time) At each acquisition, Tn command is sent at the same time for all phases (and ground) selected in "Phase operated". | |||
Incremental | (i: initial time/final time/time increment) For the first acquisition, Tn command is sent at the set initial time for all phases (and ground) selected in "Phase operated". Then at each acquisition, Tn command is sent a time increment later than the previous acquisition. Once the final time is reached, the next acquisition will be done using the initial time again. | |||
Uniform | (u: minimal time/maximal time) At each acquisition, Tn command is sent at a random time. The probability is uniform over the specified range. All phases (and ground) selected in "Phase operated" DO NOT receive the command at the same time, it is also random. | |||
Uniform gaussian | (ug: minimal time/maximal time/ dispersion) At each acquisition, Tn command is sent at a random time. The probability follows a gaussian distribution over the specified range. All phases (and ground) selected in "Phase operated" DO NOT receive the command at the same time, it is also random. | |||
Referenced operations | Use to refer the triggering of Tn to another breaker programmed state transition. See the Referenced Operations section for more information. NB: all columns must be filled for the referenced operation to work. | |||
Component | Name (or path) of the breaker to which the timing is referenced | Eref1 = {'path.name'} Eref2 = {'path.name'} ... | ||
Time | Time Tn ID of the referenced breaker's step to which the timing is referenced | Tref1 = {Tn} Tref2 = {Tn} ... | ||
Phase/Command | Activate (Phase) or deactivate (Command) the reference dependency | T1RPh = {0, 1} T2RPh = {0, 1} ... | ||
Phase operated | The list of all phases (or ground) that will change state when this step is triggered. So if after Tn-1 the A and C phases are OFF and Tn triggers B and C, after Tn phases A and B will be OFF, and C will be ON. | T1Pa, T1Pb, T1Pc, T1Pg = {0, 1} T2Pa, T2,Pb, T2Pc, T2Pg = {0, 1} | ||
ON {1} | "Colored" when a state transition shall occur | |||
OFF {0} | "Grayed out" when no state transition shall occur |
