Hello, Im looking for some STATCOM devices with active harmonic filter capability and their papers. I made a small research and got few devices(links below) but would like to compare more of them. Do you know others STATCOMs with mentioned functionality? Will be great if you share some...

In last days i found idea called "PV-STATCOM". This solution uses rest of inventer's available power. For example: if inventers works on 30% of nominal we can use 70% of his nominal as a statcom. I tried found some more information about it, mostly about how connections with grid looks like, but...

Thank you for your answer. I have supplemetary question - what will happen when we use "P" class instead of CT with a different class(more recommended). Will it negative affect on work of protection devices hardly?

Check your TSO or DSO literature, if it is. It should be freely available to make desiners job easier.

What are the advantages of use CTs with class other than "P"? I mean PR, PX, TPS, TPX, TPY, TPZ classes. I know the difference between them but couldn't find any info about pluses of using it. Have any of you had the opportunity to work with CTs with these classes?

What kind of controller unit do you mean? - controlling the whole bay; - dedicated only for controlling the synchronisation.

Hello everyone, Today i have some question about synchronisation in network. I would like to know the solutions applied by TSOs in your countries. 1. What devices you use to synchronise your network? - terminals that realise protection functions? - devices dedicated to synchronisation? 2. Do...

Hello everyone, I was searching for some practical information about PV farms but didnt get it. So I got few questions: 1. As we know inverter adjusts voltage to grid level (or transformer does it). What happen when voltage in the grid is lower or higher? Is grid sending signal about voltage...
