The application discloses a short-circuit current fast calculation and inhibition method and
system based on day-ahead production
simulation, and the method comprises the following steps: based on load prediction data, power generation prediction data and various production plan curves, a
scenario set covering multiple time sections is generated by using a
probabilistic method, and
power flow distribution is calculated as a multi-
scenario production
simulation result; through a preset
data mapping and conversion rule
library, the production
simulation result is converted into simulation data files suitable for electromechanical transient
simulation software; by using a
parallel computing framework, a short-circuit current calculation module of the electromechanical transient
simulation software is called in batches, the maximum short-circuit current of each
bus and the corresponding time section and
scenario are identified; a suppression measure
knowledge base is constructed, a candidate suppression measure combination is generated, a multi-objective optimization
algorithm is used to optimize, screen and simulate and check the candidate suppression measures under the condition of safety and
stability constraints, and an optimal suppression measure scheme is output. The application couples production simulation and transient simulation, and realizes
intelligent decision-making.
