【Abstract】 This paper briefly describes the system transient stability of the Tian- Guang AC and DC parallel transmission system,including m ain control functions of the HVDC for system stability and emergency control m easures for the AC and DC parallel system. The study shows that Tian- Guang AC and DC system can be operated stably,safely and efficiently in heavy power flows. Emergency control measures arranged are reliable to im prove the transient stability and minim ize the im pact of loss of elements in Tian- Guang AC and DC parallel transm ission system .更多还原
