HYPERSIM
How to Set a Fault Block In HYPERSIM To set a fault in HYPERSIM follow the steps presented below. Additionally, it is strongly recommended to read the Fault Element Wiki page available at 3-Phase Fault Wiki Page. 1 – Run the
circuit in steady state, without the fault application and make sure
that it works properly. 2 – Place
the fault element.
In the HYPERSIM library, there are two options for a fault element: 1-Phase fault and 3-Phase
fault (which can be configured to be 1-phase, 2-phase or 3-phase). 3 – Open
the Configuration Parameter and set the parameters: General Operation: Enable The behavior can be set as a breaker or a switch. Breaker: operates at first current zero-crossing point after POW sync . Switch: operates at exactly the moment control defines. Check the enable boxes for the times that were set and choose the phases that will operate. Coloreds are the ones that will be activated in the fault, so it can be 1, 2 or 3 phases. In gray are the phases that are disabled. For the time definition, there are four different syntaxes that are possible: -
Fixed: inform just the time
value or f:value -
Incremental: i:
initial_time/final_time/time_increment -
Uniform: u: minimal_time/maximal_time - Uniform Gaussian: ug: minimal_time/maximal_time/dispersion There is also the Phase/Command information. The Command (C) will execute the fault for the phases defined at the set time. Phase (P) operate at the time referenced to the component informed (in this case it is needed to fill the Referenced operations Component and Time columns), being used when the fault operation is associated to other equipment behavior. In General Tab inside of the fault configurations, choose control type as internal, since an internal control will be used. 4 – Add fault
control Add a constant block and a gain. In this way it is possible to set a gain of 1 and use the
constant as the controllable unit. The values
of the control can change from 0 – no phase to 15 – ABCG (all possible
configurations are available on the Wiki Page) For a three phase fault, the control value should be 7. 5 – Define
the variables that you want to monitor
Open the
sensor form of the fault block (right click à Open Sensor Form) and choose the
variables that you want to monitor. 6 – Run
the simulation 7 – Open
ScopeView
Choose the signals that should be sampled. After that, press the start button. 8 – Setting
Scopeview In the first moment the fault will not be seen in the scopes. Some Adjustments are required. The time length should be adjusted in order to view the moment when the fault occurs (ex: in this example
our fault occurs between 0.25 to 0.5 s), hence, one possibility is to set the Time Length to 0.6 s. Also, select the trigger
option. After all
these adjustments press again the play button of Scopeview. 9 – Now it is possible to see the results |
