Embodiment Construction

[0088] Such as figure 1 As shown, a method for power grid risk analysis and early warning includes risk type analysis, early warning model establishment, risk index analysis, and risk early warning management.

[0089] There is a strong correlation between power grid security risks. Specifically, the existence of one risk will cause changes in another risk. The main grid security risks include:

[0090] 1. Environmental risk, mainly refers to the safety risk caused by changes in the natural environment;

[0091] 2. Secondary system risk refers to the reliability of secondary system protection. The stronger the reliability, the lower the risk;

[0092] 3. Management system risk refers to the risk caused by whether the power grid management system is perfect or not;

[0093] 4. Collaboration risk in the network refers to the risk caused by the communication and collaboration status between organizations in the power grid;

[0094] 5. Human risks, including misoperation and violation of ...

Abstract

Analysis, prediction and warning are performed at first on power grid safety by analyzing a risk type, establishing an early warning model, analyzing a risk index and managing risk early warning, and then under the guidance of an early warning target, a safety risk early warning management organization structure is constructed, a necessary early warning function is set and exerted, and a targeted early warning scheme is formulated, organized and implemented.

Description

Technical field [0001] The present invention relates to the technical field of intelligent management of power systems, and specifically, a method for power grid risk analysis and early warning. Background technique [0002] With the emergence of large-scale combined power systems, the structure and operation of the system have become more and more complex and changeable, especially the emergence of long-distance high-power transmission lines and weak connections between systems, which have increased the occurrence of systemic accidents and caused large-scale blackouts The odds. Almost every systemic accident is related to the damage to the stability of the power system. Therefore, predictive control is needed to realize short-term and mid-long-term analysis, forecasting and early warning of power operation status, forecasting the power operation status, and taking preventive measures in time to achieve advancement. Control to ensure the safety of power supply. Summary of the i...
