Static var compensator including series circuits of three phases that are delta-connected to three-phase AC buses

Three-phase thyristor switched capacitors are delta-connected to three-phase AC buses. Each thyristor switched capacitor includes a reactor, a capacitor, and a thyristor switch that are electrically connected in series. The thyristor switches of the three phases are arranged so that the terminal-to-...

Zusammenfassung:	Three-phase thyristor switched capacitors are delta-connected to three-phase AC buses. Each thyristor switched capacitor includes a reactor, a capacitor, and a thyristor switch that are electrically connected in series. The thyristor switches of the three phases are arranged so that the terminal-to-terminal distance between respective thyristor switches of respective phases are not uniform. The three-phase thyristor switched capacitors are configured so that the thyristor switched capacitors of two of the three phases having a shortest terminal-to-terminal distance therebetween are opposite to each other in terms of connection order in which the thyristor switch and the capacitor are electrically connected along a loop path made up of the delta-connected thyristor switched capacitors.
