Substation security protection involves building a comprehensive network security defense system from multiple aspects and dimensions, including the construction of security zones for secondary protection protection of smart substation power monitoring systems, security zone boundaries, system equipment security hardening, system security trusted environment, and monitoring of the security status of monitoring system operation, to ensure the safe and stable operation of smart substation monitoring systems. Applicable to the security protection of monitoring systems in substations, converter stations, switching stations, and step-up stations or switching stations of power plants. The production control area of 220kV and above substations should be divided into control zone and non-control zone.
