Summary: | The invention discloses a control method of an AVC (Automatic Voltage Control) system. The control method comprises the following steps of carrying out initial variation on adjustable control variables to obtain a control variable set; selecting a variable horizontal number with maximum adjustable horizontal numbers in discrete variables as a problem horizontal number N; carrying out corresponding variation treatment on other discrete variables to obtain values serving as N horizontal data; obtaining values corresponding to the control variables of the system under N operation states according to an uniform designing method according to the control variable set after the initial variation; gradually calculating objective functions under each state and outputting the control variable parameter corresponding to an optimal solution; sending control commands to sub-stations by a main station according to the obtained control variable parameters to implement automatic voltage control. The control method has a premise of ensuring the optimality of an overall reactive voltage optimization result of the system; the optimization calculation frequency and scale are greatly reduced; the calculation efficiency is improved, so that the control requirement of timely response between the main station and the sub-stations can be met. |
