Economic short-circuit current limiter optimal configuration method

The invention relates to an economic short-circuit current limiter optimal configuration method. The method comprises the following steps of: firstly, establishing an economic short-circuit current limiter mathematical model according to a basic idea that an economic short-circuit current limiter exerts the maximum short-circuit current limiting effect and enables the economic cost to be minimum on the premise of ensuring the effect; according to the model, minimum purchase cost of a current limiter is taken as an objective function; taking fault node short-circuit current limitation, non-fault node voltage constraint and maximum installation number constraint of the current limiter as constraint conditions, respectively carrying out power flow calculation and short-circuit calculation, selecting short-circuit current exceeding nodes and a current limiter starting branch, and using a calculation result for the next step of genetic algorithm solution; and finally, a traditional geneticalgorithm is utilized to
