SLOVALCO - aluminuim factory - filters for 120kV grid

 

Our company, in cooperation with slovakian company ALSTOM successfully in late 2014 commissioned a unique filter compensating equipment for one of Slovakia's largest energy consumer Slovalco Žiar nad Hronom. There are two passive filters tuned on 5th and 11th harmonic. Performance of both filters is equal 64Mvar at a voltage of 120kV and filters are fixed due to stabil consumption of electric power  - so without regulation.

Subject od contract were the following services:

1) design of main components of filter compensating equipment -  (capacitors, reactors )

2) supply and installation of individual elements (through subcontractors)

3) supply and installation of protections ARCTEQ - with the possibility of evaluating individual harmonic currents = overload protection filters

4) project documentation, technical supervision

5) measurement of total harmonic voltage distortion THDU and its evaluation

6) considering of switching transients of SF6 chambers 110kV circuit breakers - existing 110kV gas insulated substation GIS 

7) assessment - models impedance characteristics of the circuit (existing and new filters ) and network models for different operating modes and power consumption + power quality metering before / after refurbishment.
