New Method of Selecting Location of Transformer Substation
Juan Chen · Gao dianya jishu · 2007
A fuzzy analysis hierarchy process was applied to select location of transformer substation to avoid the problem of disaccord of judgement matrix in analysis hierarchy process.Fuzzy analysis hierarchy process is as follows:firstly,to build the fuzzy consistent matrix by building hierarchy structure chart,then to synthesize all schemes to obtain the optimum location of transformer substation.The selection of the location of transformer substation must consider all factors,for example:closing the center of load,making the electric network more reasonable,entering line and eliciting line easily and being more economic,et al.The 220kV transformer substation location was evaluated to obtain the optimum location,where five factors must be considered such as:structure of electric network,outer condition of location,analysis of investment,construction of earth grid and special predominance.
