Abstract:The structure of power grid in China is complex with the lines widely distributed, while the abnormal climate changes in recent years have also been causing extensive and long-running galloping, which leads to frequent mechanical and electrical faults. Especially since 2007, weather conditions and processes that may induce galloping and thus have a great impact on the operation of tranmission lines have been occurring frequently, and the statistics show that the galloping of iced transmission lines has been the primary cause of line failure and outage. For most traditional anti-galloping techniques, the induction process of galloping is seen as the main target for prevention. So based on the basic principles of "galloping avoidance, galloping resistance, antigalloping, and galloping measurement", the technical response system is constructed for gallopinginduced failures in power grid, in which the prevention and control measures mainly includes the drawing of galloping distribution maps, the formulation of standards for antigalloping design, and the proposal of various schemes for device design, detection, application and evaluation, etc. With years of improvement, the current technical system has demonstrated good prevention and management effects but lacks practicability and operability during galloping. It is an attempt to review and summarize the advantages, weakness and targeted improvement measures in the existing technical response system to power grid galloping, as well as the recent research results in various related fields, such as nonlinear dynamic oscillation mitigation, galloping mechanism, artificial intelligence. Furthermore, the technical areas and research directions are put forward where better effects of galloping response may be achieved in the future, aiming to provide references for the prevention and mitigation of power grid failures and the operation and maintenance of lines.
