The invention provides a
power grid operating risk recognition and prevention method and
system. According to the method, a
power grid model is extracted with the CIM as the standard, and operating measurement data of a
power grid are imported into the model at a fixed period to form a near-real-time
operating environment; the power grid operating risk grading standard, an electrical topology analysis
algorithm and an expert rule base are introduced under the
operating environment to set up a power grid operating risk recognition and prevention
bank, an auxiliary platform integrating active risk recognition, accident evaluation and restoration control is set up, the data under the power grid real-time operating mode are integrated through the CIM standard, the problem that
information system data set up by different manufactures can not be shared is solved, and the sound data support is provided for the power grid safety evaluation; on this basis, the evaluation standard for reasonably evaluating and grading operation risks is increased, and the power grid operating risk recognition and prevention
system is constructed; an operating
risk prevention and control work mode with the
system operation as the center and without participation of related departments together is achieved, and the operating
risk prevention and control work level of the power grid is improved.
