On-line reactive power optimization control method based on real-time simulation system

The invention relates to an on-line reactive power optimization control method based on a real-time simulation system. The real-time simulation system is utilized to construct a real-time grid simulation model; a program is written in the batch script file of the real-time simulation system, and running data are extracted from a running interface and outputted; a reactive power optimization program package reads needed data, executes optimizing computation, and outputs a computation result, the scripting language of the real-time simulation system is used for programming to set the position of a transformer tap and the switching of a capacitor-reactor bank, and finally, the setting is transmitted back into the real-time simulation system; the real-time simulation system is utilized to receive and execute the setting transmitted back by the reactive power optimization program package in batch, corresponding action is conducted on the running interface, and thereby the on-line reactive power optimization model
