Design and Implementation of Real Time Coordinated Safety Control Technology for AC/DC Power Grid
The real-time coordinated safety control technology of AC/DC power grid is proposed to address the oper-ational risks of transient stability,weak damping oscillation and frequency stability in the AC/DC hybrid transmission end power grid.According to the characteristics of different stages after disturbance of the feeder grid at the sending end,the real-time coordinated safety control technology of the AC/DC power grid fully utilizes the control performance of power electronic devices,coordinates and optimizes various stable processes such as transient stability,frequency stability,and dynamic stability,and performs additional control.Using HCM3000 software and hardware platform of Xuji as the stability control execution unit,the research on the real-time coordinated safety additional control technolo-gy for AC and DC power grids is carried out,and the online optimization of control strategies is achieved.And the ef-fectiveness of the real-time coordinated safety control strategy for AC and DC power grids is verified under laboratory conditions.
