| Abstract: | The continuity of chemical production demands for the reliability of electricity supply.Because of large number of intermediate relay and time relay etc.,applied in traditional automatic devices,the reliability of electricity supply is adversely affected.The solution is put forward that automatic stand-by power switching device for double circuit power supply in 6kV substation should be controlled by PLC(based on Siemens S7 series),to improve the reliability of electricity supply greatly. |
