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 failure simulation method, system and storage medium, belonging to the technical field of electric power systems and automation thereof. The method of the present invention is based on the security control strategy model and the security control on-duty strategy, and generates a security control refusal scene set through enumeration and combination, and generates an online security and stability analysis oriented method according to the set operation of the security control refusal scene set and the security control on-duty strategy The security control device refuses to operate the fault set, and uses cluster computing to realize the online safety and stability assessment of the security control device's refused to operate the fault set. This method can adapt to changes in the power grid operation mode and security control strategy model, accurately simulate the impact of security control device refusal failures on the safe and stable operation of the power grid, discover and reduce the risk of power grid operation caused by security control device refusal in advance, and effectively improve power grid accidents. 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...
