Reactive power compensator |
摘要 |
A first SVC is connected to a first bus. A first SVC control unit controls the first SVC. A first fluctuation-component-voltage generating unit includes a voltage reference circuit that outputs a voltage reference value. A second SVC is connected to a second bus. A second SVC control unit controls the second SVC. A second fluctuation-component-voltage generating unit includes a first-order-lag control block with limiter that generates a comparative voltage that follows a bus voltage of the second bus with a predetermined time lag characteristic and is limited within a predetermined range. An impedance value XS1 of slope reactance of the first SVC is set smaller than impedance value XS2 of slope reactance of the second SVC. |
