Paralel Apk
Donald
I can't seem to understand why my glass is acting like a mirror when is paralel to camera axis. I have used the same settings in other situations and this usually won't happen - the only diference is the vray version: 1.5.RC4. I'm posting to images to illustrate the problem.
Possibly checking the 'affect shadows' option to allow light through the glass and illuminate the area on the other side will reduce this. Alternatively you can reduce the white swatch in your falloff map to a lower value. However I think it is the first option.
@Dani - after I was about to quit and use a standard material I remember to try with new geometry - I remove the planes and build new ones and checked the NORMALS! I couldn't believe that the normals where one of the sources of the problem (force 2 side should deal with it, shouldn't it?). The glass is looking like glass now and not like a chrome mirror. Still need a lot of tweaking, but it's getting somewhere now!
hi,
I have simple sfc without END. When a cancel condition of paralel seciton is true the sfc start from begining. But when it reach the paralel section again it stuck (no steps are active) even if the cancel condition wasnt true .
If I cancel whole SFC manualy it infinite stay in canceling status. Restart of SFC module helps to rid of the canceling SFCs.
any help pls?
I have an instalation where the daily peak loads cannot be served from the grid when power demand is higher than 600 Kw. So I was trying to configure a three phase quattro configuration + battery bank to serve the worst case150 Kw needed during 2 hours a day, to add the energy that loads demand during these hours. It is rather similar to peak shaving scenario.
My question is if there is possible to connect Inverter output in paralel to grid (provided 3 phase compensation). Reason is not to oversize inverters, just for the 2 hours where power assist should be needed
My idea was configuring Assistants with an AC current sensor, so keeping quattros inactive until load current demand achieves a certain value. When this current is present we start inverters in Power Assist mode, as that will sync to grid with frequency and voltage, so we can paralel output to grid safely. Power control through Ve-config can keep power from quattros below limits. A simplified view as follows (obvious lot of the details avoided)
The scenario is similar as we do when we connect several 3phase gensets in paralel to achieve load demands.
When adding ESS grid meter at grid side you need to connect only input of your inverters and they will give full capacity to cover your load (over set-point) if you configure grid set-point in example to 600kW.
No need to connect inverter output to anywhere if you are not needing back-up when grid fails. That size of system you definitely should have Victron specialist to do all calculations and make sure that system comply to local regulations.
Hi Janieronen, thank for your time
I need to setup configuration to "add" energy to grid , when loads demand more than 600 KW (no to replace grid by quattros or oversizing quattros that also is not feasible at that power load).
Load profile shows that need is below 150 Kw during less than 2 hours, so it is mandatory that grid and inverters work in paralel during that period of time. I emphasize that is not feasible at those powers to pass all Energy through quattros. That is the reason for paralel configuration
It is not feasible to size inverters to give themselves full load, or more than 600 KW, so paralel connection is needed (such as happens when you put gensets to work in paralel). So requirement is that when the demand request Grid will spouce 600 KW and Quattro outputs in paralel to Grid, will add the 150 Kw from batteries, sincronized with Grid (that is what Power Assist does)
Hi. When you link only input to network there is no load side energy flowing through inverter. You parallel inverter with loads (connect input side to your installation) and normally loads are powered from grid. When load exceeds grid set-point your inverters begin to transfer energy to grid connection and it flows to your loads.
There is mockup from my installation. In my on test system I have nothing connected to AC-OUT and inverters work only as energy storage to charge night&solar and push energy to my loads when Tarif is high or need peak shaving. I use node-RED to add more controlling options. In that example you need multiplusses capable of providing that extra 150kW and grid will provide rest. You do not need inverters capable of passthrough 750kW.
Question: where do you configure peak shaving Grid power limit to start adding power to loads from Inverters AC-IN ?
Seems easy when you use power assist to grid power using the inverter, channel, but I dont see how to trigger when loads are being sourced paralel to inverter.
Oh, Oh Janieronen.
It is quite simple and I didnt even considered the possibility to reverse energy to loads from AC-IN
So what you say is that not pushing energy to grid, but to source stored energy from battery bank , in paralel with grid, to serve loads, under configured conditions, using AC-IN.
Yes :) Multiplus and Quattro are bi-directional inverters and all you need is design rules for control system. Hand out these to your local Victron installation company so they can plan what needed for system to meet your requirements.
First to be able to feed-in even energy is not going to grid you need to use ESS. And to get ESS working your installation must comply with local feed-in regulations. That can be tricky as not all devices have compliant to all regulations. Also there are some new inverters which cannot yet to be connected in large installations. Be sure that talk with specialist before ordering anything.
I'm developing a healthcheck API that needs to call several endpoints. The idea is that, if any of those EPs fail, I have to capture the fault and incorporate that into the response. I thought about creating a main sequence that calls other leaf sequences, and each leaf sequence has it own fault sequence. This diagram should make things clearer:
If all the sequences process successfully, everything goes well and I'm able to process the response, however, if there's a fault within one of the leaf sequences, the corresponding faultsequence is executed, but I don't know how to return the flow of execution back to the main sequence. What I want is that, if a exception occurs in sequence B, fault sequence B is executed and then the execution flow goes back to the main sequence and then to sequence C.Even better it would be if I could execute all the leaf sequences in pararel, and just gather all the results in the end. I know that iterate mediator sort of do that, but from what I understand the semantics are not the same of what I want.Anyone has thoughts on this?
EDIT: so it seems the clone mediator is what I'm looking for, however I'm still not able to get it working the way I need to. Since I'll be connecting to different platforms, the response formats are distinct. Also, I need to treat situations such as timeouts, 500 response codes, etc. Therefore, I can't simply call an endpoint from each target - for each backend platform I've created a sequence that does all this logic, and populate some properties so that I can populate the final response ("platform A = up", etc). My expectation would be that all the target sequences would be processed in paralel
This is my main sequence. I use a clone mediator and target it to 2 different sequences, which do the actual invocation of the EP and treat the response (I'm using only 2 for now, but in the future will be many more). The sequences also update some variables to reflect the status of the backend platforms ("platform A = up", etc).
My expectation would be that the aggregate mediator would wait for all the target sequences to execute, by then all the properties would be properly populated and I could use the payloadFactory to properly format the response. However, from the logs I can see that, even though the aggregate does aggregate all the responses from the target sequences, the properties are not properly populated and therefore the response is not correct.
You should try an iterate mediator/clone & aggregate mediator (scatter-gather pattern) construction. The iterate allows you to execute multiple sequences in paralel while the aggregate will collect the responses. You can have the separate sequences deal with fault handling and return either the expected response or some fault. You can then check the aggregated result for any faults.
For Sinterklaas(sort of christmas but then in the netherlands and in beginning of december) i whanted to make a DIY Letter light with a arduino and rgb diodes.
I haven't used a arduino for 1 year and i never make electronic things.
So i whanted to know what resister i would need.
Look closely at the data sheet you linked from Sparkfun. Each of the RGB LEDs have 4 wires - a common ground and one each fro the red, green and blue LEDs housed on the same component. Each individual LED needs a resistor, and each resistor will need to be selected to provide 20ma or less current, using Ohm's law. The circuit you drew will not do what you describe.
The responders before me didn't mention this explicitly (they did tell, but not in these words), so i will do so:
You're mentioning that your RGB LEDs are supposed to be connected in series.
But each RGB LED consists of 3 LEDs in parallel.
This means you can't do what you proposed here.
Chris and Larry worked out a solution for this so you'll still be able to do your project in time on December 5th.
