Through summarizing the methods and steps of making plan for 10kV medium-voltage distribution network of newly-built development zone

the crucial problems and solutions needing attention during making plan for newly-built development zones are emphasized.The principle is proposed that the planning for newly-built development zones should not only meet the requirements of urban power grid planning

but also realize the actual characteristics which are appropriate to the zone.Such issues as the load index of the zone

the site selection and capacity determination of the substation

the setting of switching station and the selection of power-supply pattern are described

so that the distribution network for newly-built zone can furthest satisfy the increasing power consumption demand.
