Network safety surveillance method for intelligent network equipment of digitalized transformer satiation

Abstract

The invention relates to a network safety surveillance method for intelligent network equipment of a digitalized transformer satiation. The method comprises the following steps that: a monitoring system of a digitalized transformer satiation is established; an operator station of a substation control layer, spacing layer intelligent equipment, process layer intelligent equipment, and network layer intelligent switch are respectively connected by a network, wherein the operator station includes a data acquisition module and an industrial control software platform; based on an SNMP of a standard network management protocol, network condition information and external access information of the spacing layer intelligent equipment, the process layer intelligent equipment and the network layer intelligent switch are sent to the operator station by the network; the operator station collects the network condition information that is issued to public in a standard format; and the collected network condition information is processed by the industrial control software platform and the processed network condition information is presented for an operator in charge. According to the invention, a network condition of each intelligent equipment can be real-time supervised. When that the network condition is abnormal or there is an unauthorized access to the network is detected, alarms of a plurality of types are triggered, so that network security and information safety of the automatic system of the digitalized transformer station can be ensured.

Description

technical field [0001] The invention belongs to the network information security monitoring technology of a digital substation system, and relates to a network security monitoring method for centralized monitoring and management of all intelligent network functional devices in a power system full digital substation. Background technique [0002] In the digital substation system, due to the use of electronic transformers and intelligent primary equipment, the digitization and optical fiber of information transmission are realized through the process layer network, the original large number of secondary cables are greatly reduced, and the investment in substation construction and countermeasure costs are reduced. At the same time, the realization of secondary protection and automation functions is more flexible and reliable. [0003] In the digital substation system, a large number of industrial switches have been added compared with the original integrated system to realize t...
