Support System for Operation Status Awareness and Troubleshooting of UHVDC Transmission System
The transmission capacity of ultra-high voltage direct current(UHVDC)transmission system is huge.Once a fault occurs,it will bring tremendous impact on the operation of the power grid,bring about a number of problems such as power flow overload,insufficient reserve,and frequency drop,and induce chain failure.Therefore,it is necessary to adopt a comprehensive Precautions.This article describes the specific ideas and implementation methods of solving problems from the overall solutions to the handling of UHVDC faults,the risk assessment and prevention in advance,the real-time monitoring of events,and the assistance in emergency recovery afterwards.The method mentioned above has been operated in some regional and provincial power companies for demo purpose,and has played an important role in the handling of DC blocking events many times.
