Research and Application for Remote Testing of UHV Digital Substation Without Power Cut
Aiming to solve the issues of remote testing during turning UHV digital substation,this paper presents a new approach for the remote testing without power cut.The circuit for remote testing is determined through associating the network structure of the digital substation with the field connection,which is analyzed in order to determine several feasible remote testing methods.Then improve the drawbacks of these methods,and the improved method is applied to the UHV project in the Huxi substation,which examples its superiority.Using improved uninterrupted remote testing method will not only simplify the construction,save a lot of checking workload,make work efficiently,speed up the progress of the project,but also make the remote testing safe and reliably in the technical to make normative standards for the future work.
