| Abstract: | In order to select reactance ratio of series reactors in reactive compensation capacitors bank properly to ensure safety of the capacitors, by methods of circuit analysis and ATP-EMTP simulation, the influences of reactance ratio on switching inrush current, high frequency harmonics over current, switching inrush voltage, and re-fire overvoltage etc. is calculated and analyzed The relevant curves between reactance ratio and the inrush currents/inrush voltages mentioned above are given. The optimum ratio is determined under various operation conditions. A proposal is made for application of adjustable reactors, therefore it is possible to regulate the reactance ratio in accordance with actual operation conditions. |
