摘要
Abstract
HVDC system may cause sub-synchronous oscillation （SSO） occurred in thermal power units near rectifier station. To ensure secure and stable operation of AC/DC power transmission system from Hulun Buir to Liaoning, the possibly occurred subsynchronous oscillation （SSO） of turbogenerating units in Hulun Buir League, which might be caused by HVDC power transmission system from Hulun Buir to Liaoning, is studied by digital-analog hybrid simulator, and the risk of occurring SSO under different operation modes of AC/DC power transmission system from Hulun Buir to Liaoning is analyzed in depth, besides, the impacts of operating conditions of HVDC power transmission system on SSO are studied. The effectivity of adopting SSO damping controller in control system of HVDC power transmission project is verified by results of hybrid digital-analog hybrid simulation, and corresponding suggestions are given.关键词
