Signal Flow Graph Analysis Method of Power Grid

A method of calculating grid voltage and power distribution by signal flow graph was proposed based on basic electro circuit theory. Signal flow graph was induced into power net grid calculation. The concept of generalized calculating resistance was proposed and phase flow graph was obtained. This method shows definitely physical significance and good vivacity. This method could not only visualized analysis voltage and current , but also analysis power flow, which offers a new method for net work flow tracing and network loss calculation in electric power market.
