Design and Implementation of HVDC System Power Automatic Control

摘要

With the increasing number of UHVDC transmission projects in China,the design,construction,operation management and equipment manufacturing level of China's HVDC transmission projects are also in the leading international level.But the equipment of converter station in our country is basically in operation state,and the dispatch adjusts power frequently according to various reasons.Manual power modification by operators is not only cumbersome and prone to make mistakes,but also easy to incur bad records for inquiring.In this paper,through an automatic power technology,the standard power curve of dispatching is imported into the operator control system,which runs automatically through the operator control system.The automatic power curve setting process realized by the method can reduce the manual operation,reduce the probability of misoperation,and improve the operation reliability.Operators are very satisfied with this automatic power curve,which greatly improves the efficiency of converter station.
