A Study on SSO Restraint and Coordination Control under Rapid Development of Clean Energy

Xiaoqing Yan and Xinting Huang
Abstract—The contrary distribution between Clean Energy Base and load center of China has pushed the rapid development of UHV transmission, and SSO (Subsynchronous Oscillation) caused by multiple HVDC (High Voltage Direct Current) power transmission system has been more and more concerned by experts and scholars. Subsynchronous damping controller (SSDC) has been one of the most common restraint measures. The coordination control of SSDC is investigated in this paper, in the background of the alternative-direct transmission power system of Guizhou province. Three conclusions are verified by theoretical analysis and numerical simulations. Firstly, the SSDC and subsynchronous excitation damping controller (SEDC) are decoupled and set separately in the SSO restrain. Secondly, the coordination control of SSDC in different converter stations is necessary. At the same time, the generator speed can be applied as input signal for an effective restrain with the rapid development of communication technology. The advices proposed in this research can be helpful to the rapid development of HVDC transmission system.

Index Terms—Subsynchronous oscillation, HVDC power transmission system, Subsynchronous damping controller, Subsynchronous excitation damping controller.
