Risk Assessment Method for DC Operation in Converter Stations
To conduct a reasonable risk assessment of DC operations in converter stations,a scientific risk assessment system needs to be established.Firstly,by evaluating the five major risks of high-altitude falling,mechanical injury,electric shock,object impact,and fire and explosion in DC operations,focusing on the risk of personal injury,using the combination number based OWA operator to remove the influence of extreme values,and then applying the work condition hazard assessment method to construct a risk assessment system.Finally,based on practical work analysis,it was confirmed that the results of the risk assessment were consistent with the actual situation on site,and the feasibility of applying this method to the risk assessment of DC operations in converter stations was verified.
