Static capacitor bank (parallel connection)#

The Static capacitor bank (parallel connection) block simulates a three-phase battery of static capacitors (BSC) included in load nodes to compensate for reactivepower losses due to the load, as well as to control voltage in assemblies.Mathematically, this block is the negative reactance (capacitance) calculatedwhen the capacitors in the bank are connected as per the star circuit using the following formula: (1) :

(1)#\[ X_{\mathrm{с}}=\frac{U_{\mathrm{н}\mathrm{о}\mathrm{м}}^{2}}{Q_{\mathrm{н}\mathrm{о}\mathrm{м}}} \]

where:

\(U_{rat}\) - rated bank voltage, [kV];

\(Q_{rat}\) - bank rated reactive power, [Mvar].

When the capacitors in the bank are connected as per a triangularcircuit, the phase resistance is calculated as: (2) :

(2)#\[ X_{\mathrm{с}}=\frac{3\cdot \mathrm{}U_{\mathrm{н}\mathrm{о}\mathrm{м}}^{2}}{Q_{\mathrm{н}\mathrm{о}\mathrm{м}}} \]

The triangular circuit is used in BSC with rated voltage up to 1 [kV]. The block automatically calculates the resistance using the appropriate formulaunder rated voltages up to 1 [kV].
