Comprehensive single-line diagram for the 220kV Minsheng Substation power distribution system. The drawing illustrates a double-bus configuration at multiple voltage levels (220kV, 110kV, and 10kV) with two main transformers. Key components include:
Main Equipment
– Two main power transformers (1# and 2#)
– Two station service transformers
– Multiple capacitor banks for power factor correction
– Bus coupler arrangements at each voltage level
Transmission Lines: Multiple transmission circuits including Gengsheng lines (I, II, III), Shengsha lines (I, II), Zhangsheng line, Shengtuo line, Gaosheng II line, and several distribution feeders (Minsu, Minye, Minha, Minchai, Minji, Minxin, Mintu lines).
The diagram employs standard Chinese electrical notation with disconnectors, circuit breakers, transformers, and protective devices clearly marked using conventional symbols. Equipment identification numbers (e.g., 951, 952, 982) are provided for operational reference. Completed in March 2016, this technical drawing serves as the master reference document for substation operations, maintenance, and future modifications.
