I. Requirements Analysis

The rapid advancement of quantum computing poses a serious threat to existing cryptographic technologies. Guided by the strategic requirements of the global energy internet, the power industry adheres to the principles of "security zoning, dedicated networks, horizontal isolation, and vertical authentication." It has issued the "Notice on Matters Decided for Research and Application of Quantum Communication Technology," committing to explore the application of quantum communication technology to achieve technological upgrades and ensure network information security.

The Quantum Network Management System centralizes and unifies monitoring and management of quantum infrastructure resources within enterprises. By adopting automated operations, it progressively transforms traditional decentralized, isolated, reactive, and inefficient management approaches into centralized, comprehensive, proactive, and efficient ones. This enhances system fault response speed, reduces risks associated with manual operations and management, thereby achieving simultaneous improvements in both management efficiency and quality of information systems.

II. Working Principle

The Quantum Network Management System is a network management device capable of presenting an overview of quantum cryptographic networks. Serving as the "nerve center" of the power system's quantum security protection framework, it unifies the management of quantum communication equipment, quantum key resources, and network topology. This enables the construction of a "quantum-classical hybrid" security protection architecture, providing comprehensive, multi-layered security safeguards for the entire power system chain.

The system displays real-time network relationships between quantum devices and the operational status of quantum links within the quantum cryptography network through a visual interface. This enables users to conveniently and efficiently view quantum device network configurations, monitor device operations, understand device conditions, identify alerted devices/links, and analyze fault causes.

V. Typical Applications

1. Security Management of Power Dispatch Command Systems

① Secure Transmission of Dispatch Instructions: Establish quantum-secure tunnels across the five-tier dispatch system (National Dispatch Center → Regional Dispatch Center → Provincial Dispatch Center → Municipal Dispatch Center → County Dispatch Center), implementing dynamic "one-time-one-key" encryption. This reduces the bit error rate from the conventional 1e-6 to 1e-18.

② Provide quantum-level protection for SCADA system "four remote" data (remote measurement, remote signaling, remote control, remote adjustment), preventing command hijacking and data tampering;

③ Establish a "quantum-secure envelope" for dispatch commands, integrating specialized power-sector encryption algorithms to ensure command transmission integrity and non-repudiation;

④ Real-time visualization of quantum communication link status, with automatic identification and early warning of interference factors such as wind vibration and jitter in overhead power cables.

⑤ By analyzing quantum signal characteristics, network fault locations are pinpointed, reducing repair time by over 40%.

⑥ Combining the power dispatch data network traffic prediction model with intelligent quantum key resource allocation to achieve bandwidth optimization.

2. Substation Security Protection and Intelligent Operation and Maintenance

① On-site automated system protection: Encrypts IEC 61850 protocol communications to prevent tampering with smart substation control commands; implements quantum-level identity authentication for relay protection devices to ensure protection action accuracy;

② Intelligent Inspection Security Management: Provides quantum-encrypted communication channels for drone inspections and quadruped robots at substations to prevent inspection data theft; delivers quantum-secure access for mobile maintenance terminals to ensure secure exchange of maintenance instructions and equipment parameters.

3. Security Upgrade for Distribution Network Automation: Quantum Protection for Distribution Network Terminals

① Provide quantum CPE encryption devices for distribution terminals such as FTUs, DTUs, and TTUs, establishing secure channels via the 5G public network and reducing construction costs by 70%;

② Innovate a "quantum + 5G" distribution network service platform, establish an ultra-low latency virtual private network, and enhance fault detection and handling capabilities in distribution grids;

③ Establish a dual-closed-loop system integrating quantum security and self-healing control, automatically switching to quantum communication mode during isolated network operation to ensure secure transmission of dispatch commands.

4. Grid Integration Safety Assurance for New Energy: Secure Aggregation of Distributed Energy

① Innovative two-stage quantum encryption solution featuring aggregation and access: First, dispersed renewable energy data is aggregated via wireless quantum encryption, then transmitted to the dispatch system through fiber-optic quantum encryption.

② Provide quantum protection for AGC/AVC commands in wind farms and photovoltaic power stations to prevent "pseudo-grid connection" and tampering with power generation data.
