Computer Program for Automatic Transmission Planning

The manual development and economic evaluation of many alternate, long-range transmission system expansions represents a tedious and difficult task. To speed this planning process, a computer program has been developed to plan automatically the new transmission facilities needed to meet a particular generator addition schedule. The program uses an economic dispatch to allocate generation, and a d-c power flow to discover circuit overloads. The program checks the ability of the transmission system to meet both normal and emergency situations. When an overload is detected, the program checks a logical sequence of methods of alleviating the overload. Suggestions are made for further developments in the area of automatic transmission planning.
