The superconducting RF system has been operated successfully in the storage ring of SSRF since July, 2008. The Superconducting RF modules integrated with 310 kW transmitters and digital Low Level Radio Frequency (LLRF) control systems are used to provide about 4.5 MV cavity voltages for 3.5GeV electron beam. The operation status of SRF systems are mainly reported here, the problems we met are analyzed, and also the operation with normal conducting cavity systems is introduced briefly. The challenge for us is to improve the system reliability and machine performance.
