| description | The invention provides a transient voltage rise suppression method, system and device for a sending-end alternating-current power grid and a medium. The method comprises the steps that voltage change parameters of all nodes of a sending-end alternating-current system are obtained, reactive voltage comprehensive sensitivity of all the nodes is calculated according to the voltage change parameters, and reactive compensation nodes are selected according to the sequence of the reactive voltage comprehensive sensitivity; when the sending end alternating current system is in the maximum load operation condition, the reactive power compensation capacity is optimized based on the particle swarm optimization, and the optimization result of the capacitive reactive power compensation capacity corresponding to the reactive power compensation node is output; under the condition that the sending-end alternating current system is in the minimum load operation condition, the inductive reactive power capacity is optimized bas |
