Design of reactive power compensation panel is much different and not that simple like standard distribution panel. When dealing with such panels, there are dozen of parameters to specify and other things to take care of.
This article is the part of Mr. Jakub Kępka’s excellent thesis work on subject ‘Reactive Power Compensation‘. I haven’t read such a good work for a long time. Excellent.
The aim of project called „Reactive power compensation panel” was to design capacitor bank with rated power of 200kVar and rated voltage of 400V adapted for operation with mains, where higher order harmonics are present. The capacitor bank was to be power capacitor based with automatic control by power factor regulator.
Bearing above in mind, first thing to do is to investigate basic requirements for capacitor banks according to the polish standards. The most important standards, that were used during design process was:
EN 61921:2005
EN 60439-1:1999
IEC 60831-2
EN 61921:2005 describes the general requirements for the capacitor bank. The most important of them are listed below:
Access to the particular elements within the capacitor bank should be easy, so that there is no problem to replace an element in case of failure
Index of protection depends of the place of the installation of a capacitor bank. If the capacitor bank is to be placed in the same place as the main switchgear or utility room next to it, IP 20 is enough.
Section construction – in a device for reactive power compensation particular sections can be determined, placing them in separate partitions or within the same cubicle.
Marking – each capacitor bank has to have nameplate, which contains information about: manufacturer, identification number, date of manufacture, rated power in [kVar], rated voltage in [V], min and max ambient temperature, index of protection, short circuit strength in [A]
