Feeder automation is one of the main functions of power distribution automation. For the implementation of domestic distribution automation, the present situation and development of feeder protection is discussed. A new scheme and new concept for optical communication based feeder system protection used in distribution network are proposed. Fully using the features of pilot protections in high voltage transmission lines and applying the fast communication among feeder protection devices, the functions, such as the feeder fault isolation, reclosing and restoration of power supply, are implemented in whole. In this way, the implementation of feeder automation is developed from concentrated supervisory control mode to distributed protection mode. Therefore, the integrated function of distribution automation is improved.

Located in Lanping County, Yunnan Province, the Jinding Pb_Zn deposit is the largest polymetallic deposit in China. The orebodies are hosted in Mesozoic_Cenozoic terrestrial clastic rocks. No igneous rocks have ever been found in the orefield. The deposit has some unique features, which can distinguish it from such sedimentary rock_hosted deposits as MVT_type and Sedex type Pb_Zn deposits. The tabular orebodies (with some veins) are hosted in the Eocene Yunlong Formation and Lower_Cretaceous Jingxing Formation, both of which consist mainly of terrestrial clastic rocks. This leads to the syngenetic model proposed by some authors. The mineralization, however, is not lithostratigraphically restricted. Instead, it is controlled by faulting and doming. The major feeder fault is F 2, a thrust that had been formed at an earlier stage but was modified during the later doming. The orebodies occur in both hanging wall and foot wall. This, together with the absence of hydrothermal sediments and the ore textures of replacement and space_filling, suggests an epigenetic, hydrothermal origin. The Pb isotope data show that the metal is mainly derived from the mantle, mixed with less amounts of crustal lead. The S isotope data show a trend of δ 34 S pyrite >δ 34 S sphalerite >δ 34 S galena , indicating an equilibrium between the min_erals, and the sulphur is mainly of crustal source. The study of fluid inclusions in sphalerite and in associated gangue minerals (quarts, celestine, calcite and gypsum) shows that the homogenization temperatures range from 52℃ to 309℃, clustered around 110~150℃, with salinities of 5.09%~19.63% wt NaCl equivalent. The pressure was 32.5~22.6 MPa, corresponding to an ore_forming depth of 0.9~1.5 km.
