摘要

中国特高压交直流电网发展过渡期，电网特性持续发生重大变化，传统的安全稳定防御技术和措施难以适应，亟须对电网安全防控体系进行提升。在梳理电网大的特性变化基础上，分析了适应特高压交直流电网实践的“系统保护”的必要性及需求。提出了系统保护的体系设计，包括设计思路、总体构成、具体措施等。提出了系统保护关键技术，并着重介绍了全景状态感知、实时决策与协同控制、精准负荷控制技术的需求及框架。最后，简述了国家电网在系统保护建设上的实施方案，为特高压交直流大电网安全稳定运行控制提供了解决方案。

Abstract

During the development transition period of China's ultra-high voltage(UHV)power grid

the characteristics of power grid continue to change significantly. The traditional defense technologies and measures on security and stability are difficult to adapt

thus the security prevention and control system is needed to improve. The necessity and demand of “system protection” to adapt to construct UHV AC/DC power grid is put forward based on the characteristic-changes of power grid. The design of system protection is proposed

including design ideas

overall composition and specific measures. Then the key technologies of system protection are put forward

and the requirement and framework of panoramic state perception

real-time decision-making and coordinated control as well as precision load control technology are focused on. Finally

the implementation scheme of system protection construction for State Grid Corporation of China is briefly illustrated

which provides a solution for the safe and stable operation control of large-scale UHV AC/DC power grid.
