Successive disturbance universal model for real-time simulation and control method thereof

Abstract

The invention discloses a successive disturbance universal model for real-time simulation and a control method thereof. The successive disturbance universal model is divided into a three layer structures, wherein a first layer is used for dividing a plurality of disturbance scenes into multi-stage successive trigger so as to achieve that different disturbance scenes are successively happened according to a special time sequence, a second layer is used for setting which disturbance is triggered by each stage, different stages of disturbance scenes are independently controlled and are not disturbed, and a third layer is used for triggering a special component to generate designated type of disturbance within designated time. The successive disturbance universal model proposed by the invention is clear in structure and high in expansibility, the complicated disturbance scenes in wide types and successively generated can be flexibly handled, and the problem of poor flexibility and universality of a traditional disturbance scene one-by-one construction method is effectively prevented.

Description

technical field [0001] The invention relates to a real-time simulation-oriented sequential disturbance general model and a control method thereof, belonging to the technical field of power system simulation modeling. Background technique [0002] Modern power grid catastrophic accidents are mostly caused by chain disturbance events. These power outages generally start from the failure of a certain component in the system. Due to multiple factors such as improper or untimely control measures, unreasonable power grid structure, and relay protection device misoperation or refusal to operate, a series of subsequent disturbances or components are triggered. Under the impact of cascading disturbances in the power grid, it will eventually lead to large-scale power outages in the power grid. In the real-time simulation environment, constructing and simulating successive disturbance scenarios, and testing the impact of each level of disturbance impact on the safe and stable operatio...

AI Technical Summary

Problems solved by technology

When simulating multiple complex disturbance scenarios, there are problems such as complex logic functions, nesting of multiple levels of disturbance scenarios, and poor scalability and flexibility of scenario types.

For complex safety and stability control systems, there are many disturbance scenarios to be verified and there are couplings, and the workload of modeling and debugging successive disturbance scenarios often increases geometrically.
