摘要

中国渝鄂背靠背柔性直流工程投运以后，异步运行的中国西南电网面临的主要问题变成了自身频率问题，而现有安控系统只能解决局部问题，因此需要构建西南电网交直流协调控制系统。在处理手段、协调方式和构建模式上，对设计西南电网交直流协调控制系统进行了解析。详细阐述了系统的总体架构，在站点配置和通信设计方面介绍了建设的原则。从西南电网交直流协调控制系统的设防原则和控制策略方面详细说明了交直流协调控制系统的功能和作用，并且将构建的交直流协调控制系统应用于实际西南电网中，同时进行了详细的试验验证。

Abstract

After the operation of Chongqing-Hubei back-to-back flexible DC project in China

the main problem in the asynchronous operation of southwest power grid has become its own frequency problem

and the existing stability control system can only solve local problems

so it is necessary to construct AC/DC coordinated control system of southwest power grid. The design of AC/DC coordinated control system for southwest power grid is analyzed in terms of processing means

coordination modes and construction modes. The overall architecture of the system is described in detail

and the principles of construction are introduced in the aspects of site configuration and communication design. The function of AC/DC coordinated control system is described in detail from the aspects of fortification principle and control strategy of AC/DC coordinated control system. Moreover

the AC/DC coordinated control system is applied to the actual southwest power grid of China

and the detailed test verification is carried out at the same time.
