Visual debugging method for electric power system looped network load flow calculation

The invention provides a visual debugging method for electric power system looped network load flow calculation. By means of searching for a power grid topology model and imaging the power grid topology model, the structure and the current running conditions of a power grid are reflected visually. The visual debugging method is applied to electric power system planning and design and real-time monitoring of the electric power system running state, so that complex looped network load flow calculation and debugging work is greatly simplified, the load flow maintenance work is simplified substantially, and the debugging efficiency is improved.
