Automatic graphic generation of external network circuit diagrams based on CIM

Abstract

To make external network power station drawing circuit diagrams more expediently, an automatic graphic generation based on CIM standard is developed. First, with the screen centre as basic point, the screen is divided into 4 areas, and various equipment lay aside separately according to certain rule. Next, voltage level structure table, bus bar structure table, transformer structure table and switch structure table are introduced to record power station topology model and equipment element location, and the element specific formula has been given. Last, the concrete steps of external network power station circuit diagrams automation generation are established. The example shows the feasibility of the proposed approach.
