双碳背景下特高压电网安全防御系统设计

Design of Security Defense System for UHV Power Grids Under the Dual Carbon Background

在当前我国特高压交直流混联电网具有“强直弱交”和电力电子化特征的双碳背景下,为有效降低电网大面积停电风险,有必要构建安全可靠的电网安全综合防御系统,确保我国电力系统安全稳定运行。在我国已有的传统三道防线基础上,确定了适应我国电网在双碳背景下的特高压交直流电网安全防御系统应具有的目标和设计原则,设计了特高压交直流电网安全防御系统的总体架构、主要功能和具体的配置方案。

Under the dual carbon background of AC and DC hybrid power grids have the new feature of"strong HVDC and weak AC system"and power electronization,in order to effectively reduce the risk of large-scale power outages in power grid,it is necessary to build a secure and reliable comprehensive defense system to ensure the stable operation of the power system.Based on the traditional three defense lines in China,the objectives and design principles of the UHV AC and DC power grid security defense system that adapt to the dual carbon background of China's power grid were determined,and designed the overall structure of the UHV AC/DC power grid security defense system,main functions and specific configuration schemes.
