| Abstract: | New functions are added to remote control circuit,such as manual handle,synchronous switch-on enabling,synchronous switch-on disabling,error-prevention electronic lock and remote control enabling,and their operating principles and features are analyzed.The checkout scheme for synchronous switch-on function/accuracy,voltage blocking,differential voltage blocking,differential frequency blocking and diffe-rential phase-angle blocking is proposed.The statistics of remote control operations in four 220 kV substa... |
