# 溪洛渡送电广东直流输电工程双回直流协调控制策略分析Analysis the Strategies of Double DC Coordinated Control for Xiluodu-Guangdong HVDC Project

The project of Xiluodu right station-Guangdong ±500 kV double HVDC systems erected on the same tower is the first project that double HVDC systems erected on the same tower at home, its function of control and protection increased the double DC coordination control function in addition to all function of conventional DC project. This paper was written with the background of Xiluodu-Guangdong HVDC project, introduces the differences in control system layered structural between Xiluodu-Guangdong HVDC project and conventional DC engineering, from power modulation, double DC power control and reactive power control three field analyzes the double DC coordinated control strategy, the control strategy in the control host abnormal are given, and compared with the control strategy of conventional DC system.
