| Abstract: |
| The 220 kV system of 500 kV Laoshan substation is the most complex substation amongthe 500 kV substations of Shandong,which adopts dual-bus dual-subsection wiring with BP-2B relays of Shenzhen NARI. A serious equipment trip incident of bus A caused by the glitch of its components in 2003 is analyzed. The exceptional phenomenon of the two trips is explained in detail and the precautionary measures from design,manufacture,operation and other aspects are discussed. |
