Abstract: Aiming at the major problem of Zhoushan network structural change after 220 kV AC interconnection lines put into operation, the method of operation was detailed analyzed. The necessity of install the security control system was explained. The logic of control system was studied. The security and stability of control system was checked.The results indicate that Zhoushan safety control system putting into operation is able to effectively increase the interconnection line power flow.
