Analysis of Sub-Synchronous Oscillation (SSO) Caused by HVDC Transmission System

Article Preview

Abstract:

Sub-synchronous oscillation (SSO) caused by highly non-linear HVDC devices can lead to shaft failure and electrical instability of a turbo-generator at oscillation frequency lower than power grid frequency. With increasing HVDC installed in power systems, analysis of SSO becomes a great concern of electrical engineers. In this paper, the reason and process of the SSO are presented by analyzing equations of the mass-springs model. Research methods of SSO are reviewed in HVDC system. And advantages of digital time-domain simulation are demonstrated through combining with algorithm of Prony.
