| Abstract: | Aiming at the existing problems of power grid state estimation in the actual operation of system, this paper analyzed the characteristics of power grid operation and studied the debugging method which improved the state estimation correct rate, raising the corresponding, actual debugging method. Especially for loop lines, multi-circuit lines, ultra-short lines, a kind of method to estimate parameters was raised to lift the state estimate correctness, which pushes forward the practicality development of D5000 online analy-sis module application in intelligent power grid dispatching automation system. |
