Circuit Breaker, 1-Phase
Mask and Parameters
General Parameters
Name | Description | Unit | Variable = {Possible Values} | |
---|---|---|---|---|
Description | Use this field to add all kinds of information about the component | Description = {'string'} | ||
Control type | The breakers' state can be controlled from any of the following sources | CmdBlockSelect = {0, 1, 3} | ||
Internal {0} | Internal control defined in the the Timing tab | |||
External (input sensors) {1} | Target digital input on CMD sensor | |||
External (input pins) {3} | Schematic control signal; binary | |||
Ropen | Open state resistance of phase breakers | Ω | ROpen = { [0, 1e12] } | |
Rclosed | Closed state resistance of phase breakers | Ω | RClose = { [0, 1e12] } | |
Breaking capacity | Current absolute value below which phase breakers are allowed to open; applies only when the selected model type is Breaker | A | Imargin = { [0, 1e64] } | |
Base power | Base value pour PU conversion | MVA total | pBase = { [1, 1e64] } | |
Base voltage | Base value pour PU conversion | kV rms LN | vBase = { [1, 1e64] } | |
Base frequency | Base value pour PU conversion | Hz | fBase = { [1, 1e64] } |
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 breaker in steady-state; “colored” if the breaker is open and “grey” if the breaker is closed | EtatIniA = {0, 1} | ||
Network frequency | Legacy. Should be set using the parameter "Base frequency". | Hz | Freq = { [45, 70] } | |
Model type | Determine whether the component acts as a switch or as a breaker | TypeA = {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. | |||
Incremental | (i: initial time/final time/time increment) For the first acquisition, Tn command is sent at the set initial time. 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. | |||
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. | |||
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} ... |
