State estimation ( SE) is one of the basic functional modules for power dispatching control center. Making a summary of the technologies and application of SE in the preceding decades, this paper proposes practical techniques with parameter management, system debug and indicator analysis to further improve the practicality of SE. A case study on the 220 kV and above power grids of CSG demonstrates the effectiveness and feasibility of the proposed method.
