Adaptability Analysis of 110kV Power Grid Objective Architecture

Based on the current status and development trend of 110 kV power grid,some general designing concepts for the 110 kV power grid objective architecture in near future years are introduced as follows:every 110 kV power grid operates as a separated zone to provide power with a 220 kV substation at the center;the separated 110 kV zones are independent at normal conditions,while capable of supporting each other in faulted cases.
