Problems solved by technology
[0003] Existing security control failure simulations usually require the designation of security devices participating in the simulation in advance. The workload of manual setting and maintenance is extremely heavy, and it is impossible to automatically track changes in the power grid operation mode and security control strategy model, and it is difficult to objectively evaluate security control. Due to the impact of device refusal on the safe and stable operation of the power grid, it is urgent to propose a fault simulation method for safety control device refusal that can adapt to changes in power grid operation mode and security control strategy model

The invention discloses a safety control device refusal-operation fault simulation method and system and a storage medium, and belongs to the technical field of power systems and automation thereof. The method is based on a safety control strategy model and a safety control on-duty strategy. And generating a safety control refusal scene set through enumeration combination, generating a safety control device refusal fault set oriented to online safety and stability analysis according to set operation of the safety control refusal scene set and a safety control on-duty strategy, and realizing online safety and stability evaluation of the safety control device refusal fault set by utilizing cluster calculation. The method can adapt to the change of a power grid operation mode and a safety control strategy model, accurately simulates the impact on the safe and stable operation of the power grid from the operation refusal fault of the safety control device, finds and reduces the power gridoperation risk caused by the operation refusal of the safety control device in advance, and effectively improves the power grid accident risk prevention and control level.
Description
technical field [0001] The invention belongs to the technical field of electric power system automation, and in particular the invention relates to a method, system and storage medium for simulating failure of a security control device refusing to operate. Background technique [0002] With the construction of long-distance and large-capacity inter-regional AC and DC transmission projects in my country, the safety and stability characteristics of the power grid have become more and more complex. In order to ensure the safe and stable operation of the power grid, a large number of security control devices have been built in power grids at all levels. If the security control device refuses to operate due to abnormalities in the device channel, fault detection module, action execution module, and exit pressure plate abnormal exit, etc., the corresponding security control strategy will not be correctly implemented. When there are failures of security control devices at different...
