2005年3月8日 · Does ETAP model a UPS? I use SKM and it doesn't model a UPS, which is ok, because I get worst case results considering the bypass path. A UPS output is limited during a fault to about 300%, so it transfers to bypass to help clear the downstream OCPD.

2024年1月23日 · akhtar: Try the following YouTube video link which talks about including various protective devices in an ETAP model. All of the devices listed below require the appropriate data (which may be simple rating data, but may also be far more complex) included as part of the model. I believe that all are available in ETAP, with "blank" templates.

2022年8月23日 · ETAP seems more tailored/focussed on industrial power systems while PowerFactory seems to be used more for transmission power system modelling. As a result, the component models / libraries of each software package are more suited to their respective strengths / areas of focus but can also work perfectly fine for other modelling scenarios.

2017年4月10日 · Hello engineers! I'm looking for help with importing a CYME model into Etap. On Etap's official website it mentions the ability to do this but I was not able to figure out how. Below is the image from Etap's official website that shows this. Please help me figure out how to do this.

2018年6月19日 · As you may know, in ETAP there's no a "typical data" button available when modelling a three-winding transformer. I want to model a 23/0.4/4.16 kV of 3 MVA. Would it be ok to model three different two-winding transformer (23/0.4, 23/4.16 and 0.4/4.16 kV) in order to have typical values between...

2004年11月8日 · I was provided the data to model a 230/34.35 kV 3 winding transformer for a wind farm with the +/- 12.5 % regulation and +/- 8 taps. The primary-secondary impedance value for the transformer is 11.80% at nominal and 12.4% (8R tap position, 258.75 kV) and 11.81% (8L tap position, 201.25 kV) all...

2024年5月31日 · I've been using etap for a couple of months and recently I'm trying to model a 230/132/33kV YNa0d1 autotransformer in my project. The problem is, etap lets me choose between 2 winding and 3 winding transformer but no autotransformer can be inserted. For this reason I did the modeling with 3 winding transformer in YNynd1 configuration.

2009年11月7日 · I would like to request for some advice and experienc from power system and VFD folks. I am modeling a 4kV motor connected to a VFD in ETAP. The VFD is having a soft start feature. The program has options to either model the soft start as "Current Control" or "Voltage Control" or "Current Limit".

2009年3月26日 · In the dynamic motor start study in ETAP the exciters/governs aren't model (ref page 16-24 in manual). If you want to include the dynamic characteristics of your generators you have to run the motor start as a transient stability study.

2002年2月17日 · When I assign a fuse or relay from the ETAP library to the one-line diagram symbol of an existing ETAP model, ETAP plots the time-current curve offset to the right by a current factor of 1.17. When I assign the same fuse or relay from the ETAP library to the one-line diagram in a new ETAP...
