Special Session: Protection and Fault Location Principles of Offshore Clean Energy Power Generation System and Transmission System
Organizer: Dong Wang, Qingdao University of Science & Technology, China
The offshore clean energy generation, represented by wind power and photovoltaics, is rapidly developing, which contains complex control system and delivery system. For the power generation system, it could include wind turbines, photovoltaic panels, transformers, collection systems, converter stations, et. al.. For the transmission system, it could adopt hybrid transmission forms including submarine cables, offshore overhead cables, overhead cables, underground cables, and overhead lines, et al.. The environment and medium along the transmission corridor are complex and variable, making it difficult to quickly clear or accurately locate faults. Therefore, it is necessary to enhance the protection and fault location performances by: (a) aiming at the issue that the existing mathematical models of overhead/cable lines are only applicable to limited frequency bands or rely on external data, taking the line structure and dielectric environment into account, a full frequency band electromagnetic transient model should be proposed; (b) aiming at the amplitude attenuation and spectrum distortion issues of faulty generated information, novel simulation models and transducer methods require to be researched; (c) aiming at the applicability issue and accuracy issue, taking the entire faulty process into account, novel protection principle and fault location principle should be studied.
Topics:
Advanced control strategies of offshore wind farm and photovoltaic field
High-precision fault location principle
Ultra-high-speed main protection principle
High-reliability backup protection principle
Electromagnetic transient simulation modelling of power system
