• 3, Implementation requirements for secondary security

What should be classified as control areas in the power monitoring system safety protection scheme

Production control is divided into control areas (safety zone I) and non-control areas (safety zone II).Information management is divided into production management area (safety zone III) and management information area (safety zone IV). Safety Zone I Typical System: Scheduling Automation System, Sutation Automation System, Relay Protection, Safety Automatic Control System, Etc.

The production control area can be divided into control area (safety zone I) and non-control area (safety zone II); the management information area can be divided according to the different safety requirements of each enterprise without affecting the safety of the production control area.

Article 5 The State Energy Administration and its dispatched agencies shall supervise and manage the safety protection of the power monitoring system in accordance with the law. Chapter II Technical Management Article 6 The business systems based on computer and network technology within power generation enterprises and power grid enterprises shall be divided into production control areas and management information areas.

Power monitoring system safety protection evaluation work several years one Chapter

Chapter III Safety Management Article 14 The safety protection of the power monitoring system is an integral part of the power safety production management system.

The monitoring equipment that works for a long time is regularly maintained once a month. For example, the hard disk recorder will generate more heat when it works for a long time. Once the electric fan fails, it will affect the heat dissipation to avoid the abnormal operation of the hard disk recorder. Monitor the operation of the monitoring system and equipment, analyze the operation, and find and troubleshoot in time.

Article 3 The basic principle of power system safety protection is that in the power system, systems with higher safety levels are not affected by systems with lower safety levels.

Electrical fire safety inspection should be the behavior agreed and accepted by the testing party and the inspected party. Before national laws and regulations are clearly stipulated, electrical fire safety inspection should not become a hard allocation work.

Article 2 The safety protection of the secondary power system shallAdhere to the principles of security zoning, network dedicated, horizontal isolation and vertical authentication to ensure the security of the power monitoring system and the power scheduling data network.

This measure shall not apply to networks involving state secrets. Networks involving state secrets shall be managed in accordance with the management regulations and technical standards of the national confidentiality department on the graded protection of classified information systems, and combined with the actual situation of the network.

Implementation requirements for secondary security

The basic principles of the general policy of safety protection of power monitoring systems in new energy power plants are "security zoning, dedicated network, horizontal isolation, vertical authentication".

The general requirements of security protection are: security partition, network dedicated, horizontal isolation, vertical authentication. Specifically refers to: 1) Security partition.

Carry out secondary system security protection in strict accordance with the principle of "security partitioning, network dedicated, horizontal isolation and vertical authentication" to ensure the security of the company's secondary system and power scheduling data network.

The development units, users and suppliers of special safety products for power secondary systems shall do a good job of confidentiality in accordance with the relevant national requirements and prohibit the proliferation of key technologies and equipment.

x0dx0a2 project entrustment x0dx0a The construction unit submits an entrustment to the engineering design (construction) unit according to the requirements of the design task letter. The engineering design (construction) unit submits a project proposal or project implementation plan according to the requirements of the power of attorney and the design task letter, and after the review of the construction unit After approval, the contract can be signed when the entrustment takes effect.

Article 48 The electric welding machine shall be equipped with a separate switch, and its secondary side wiring shall be equipped with a protective cover.The length of the primary power cord of the welding machine should not exceed 3 meters, and the length of the welding cable should not exceed 30 meters. The outer skin of the electric welding machine should be grounded, and the loop ground wire is strictly forbidden to be connected to buildings, machinery and equipment, various pipes, metal frames or tracks.
