| Abstract: | In view of problem of higher running voltage in 750 kV power transmission and transformation system of an Area,the paper proposed a design scheme of applying SCSR of high-leakage inductance transformer into the 750 kV system.It analyzed working principle of SCSR,used electromagnetic transient simulation software to build simulation model of the 750 kV system,and respectively simulated effects of inhibiting of power frequency over-voltage and secondary arc current and capacity adjustment of SCSR under normal state and fault state of the 750 kV system.The simulation results showed that SCSR can effectively reduce steady running voltage and improve stability of the 750 kV system. |
