A method for generating style based substation main wiring graph and sub-graph is studied. Based on the promulgated automatic graphical standard of the substation

a three-layer style of layout

container and graphics is proposed from high to low. As a collection of identical pixels

the container style is the key element of graphics generation for achieving automatic type-setting of pixels within the container in different scenarios. On this basis

a kind of automatic generation method of substation main wiring graph and sub-graph is put forward according to style. A set of substation graphics auxiliary generation system is then developed through instantiation and layout of style with work efficiency effectively improved.
