| Abstract: | Dynamic compensation of power factor is a nearly ideal compensationmethod and also the direction of its development.The paper analyzes andcompares the dynamic and static modes of compensation and gives out apractical main circuit for dynamic compensation.The circuit can effectivelysuppress switching overvoltage and surge current,and it can also carry outfully automatic operation.A general structure of the control circuit fordynamic compensation,and the method of rapid measurement of active andreactive power factor are also given.The state-setting circuit for numberof condenser banks and the suppressing circuit for operation interferenceare designed that can effectively solve the main problems encountered inthe application of dynamic power factor compensation.Practical operationproves the effectiveness of the methods given. |
