Connecting process for a reactive power compensator

摘要

The electrical power supply (U) may produce three- phase current at 36 kV. The current may be passed to a distribution conductor (DL) via one or both of two switches (S1,S5) in parallel. A resistor (R) is connected in series with the first switch. Compensation components (K1-K3) are connected to the distribution conductor via individual switches (S2-S4). A control program (CP) is passed to a control circuit (CU) via a data carrier (DC). When the control circuit receives an ON command the switches are closed in order and a control signal is sent to a thyristor (T) in the first compensation component. Switching intervals may be 100 to 150 milliseconds.
