Session Abstract
One of the most fundamental characteristics of the new power system is the widespread adoption of the power electronic equipment. The millisecond-level rapid response and sequential switching control characteristics of the power electronic equipment cause the power system to exhibit highly time-varying and nonlinear dynamic behavior. Under system fault conditions, the control functions of power electronic equipment overlap with the timing sequence of relay protection decision-making. This leads to frequent failures to maloperate or misoperation in traditional relay protection technologies, making it difficult to meet the operation requirements of the new power system.
At the same time, the flexible and rapid control capabilities of power electronic equipment have also provided a new breakthrough for innovation in relay protection technology. By reshaping the control characteristics of the power electronic equipment, it is possible to effectively address challenges of traditional protection and even overcome the inherent limitations of its algorithms. This session focuses on core technologies for coordinated control and protection in power systems, including control-characteristic-enabled novel fault identification methods, the research and development of coordinated control and protection equipment, and the practical engineering application, with the aim of providing new insights and technical support for fault identification technologies in new power systems.
