[0002] along with increasingly sophisticatedization of electric network composition, in the past in the manual identification of security risk, drawbacks such as big, the narrow range of the workload that gathers, expose in the flow processs such as assessment, control, cycle length, operability difference are more outstanding, have had a strong impact on the efficient and the quality of safety risk management work.And objective, efficient, dynamic risk management system be unable to do without effective support of network system for managing.
Summary of the invention
The object of the present invention is to provide a kind of power grid risk assessment management method.Method of the present invention can reduce the probability of maloperation, can effectively carry out the risk class assessment to the abnormal running mode under electrical network normal operating mode and the maintenance mode, prevents the generation of accident, really accomplishes safety in production.
In order to reach above-mentioned purpose, solution of the present invention is:
A kind of power grid risk assessment management method, comprise the steps: 1, at first from the PI database of DF8600 integrated data platform, obtain data, this data owner will comprise two parts, a part is a real time data, comprise remote measurement amount and remote signalling amount, another part is a historical data, is the historical load of system; The risk assessment server has independent database, the result of calculation information stores of risk assessment is in the server of oneself, system server is positioned at safety three districts, system will adopt the pattern of server/customer end, system's figure all adopts the SVG figure, support the WEB browsing mode simultaneously, check The results of running for the MIS user on the network; 2, the importing of electric network model and coupling in the dispatching of power netwoks real-time system, established complete electric network model in the dispatching of power netwoks real-time system, utilize interface routine that electric network model is imported the risk assessment server system, to reach the purpose of coincideing with the electrical network true altitude; 3, set up the security risk integrated network database that is fit to safety risk management system standard; According to operation of power networks risk assessment relevant criterion, teams and groups of basic unit carry out identification and assessment to the risk of administrative area, according to the height of risk class, set up the power grid security vulnerability database in the risk assessment server system, form a power grid risk evaluation criteria; 4, normally reach the assessment of risk class under the abnormal running mode in system, utilize network topology analysis, state estimation, static security analysis and the trend computing technique of dispatching automation SCADA system, under real-time type and research pattern, abnormal running mode under electrical network normal operating mode or accident and the maintenance mode is carried out the risk class assessment, and carry out correspondingly with the risk storehouse, provide risk rating.
Beneficial effect of the present invention is: a kind of power grid risk assessment management method of the present invention is to carry out the function expansion in existing SCADA/EMS system, increase a small amount of hardware equipment, exploitation, realize operation of power networks risk evaluating system, guarantee that equipment (comprising equipment such as main transformer, circuit, bus) provides the risk situation that system may occur and provides corresponding control measures at risk situation when normal operation of electrical network and maintenance based on DF8600.Reduce the probability of maloperation to the full extent, can effectively carry out the risk class assessment, prevent the generation of accident, really accomplish safety in production the abnormal running mode under electrical network normal operating mode and the maintenance mode; Improved the security of grid equipment operation, the understanding of the potential risk that intensification operations staff and maintainer may exist electrical network when overhaul of the equipments.The present invention is from user perspective, and function is simple and practical, and picture is succinct, and is easy and simple to handle, and the user can operate by simple mouse action.
