Design Analysis Of The TCMZ110KV Transmission Project

With the rapid economic and social development of Tangshan City,and the development of the high-tech industry in the CaoPorts,the grid in Tang shan which has substantial growth in ecectricity load has become receive power from others. Based on the master plan which development by Tangshan, the speed of the electricity consumption and load will maintain a rapid growth, and all the electricity comsumption of Tangshan will reach 56 billion kWh until 2010, increased of 10.59% in a year.according to the design guidelines of the substation construction in state grid corporation, we first analyse and design 110kv substation with the actura situation of the TCMZ110KV substation based on the key issuse in the design process of the 110KV substation, and decide a feasible technical program.the second, compared the program with 110-A-2 and 110-B-4 progarm of state grid corporation,the paper propose and demonstrate the estiamed investment of TCMZ110KV substation project.
