Disclosed are a message sending method and apparatus. The method includes: a front-end device receiving a message preview instruction and sending the message preview instruction to a server; the server determining, on the basis of the message preview instruction, whether a message currently corresponding to a message type satisfies a sending rule, and if so, making an electronic message correspond to the message type, and sending the electronic message to the front-end device; the front-end device outputting and displaying the electronic message for a user to view; and the user triggering a message sending instruction after confirming same, so as to complete the sending of the electronic message.

The disclosure provides a method for monitoring a short-term voltage stability of a power system. The method includes: obtaining a topology and time series of a current power system; inputting the topology and the time series of the current power system into a trained spatial-temporal graph network model, the trained spatial-temporal graph network model being obtained by classification learning on a spatial-temporal graph network model based on a simulation sample dataset; outputting a status of the short-term voltage stability of the power system; and sending an alarm signal in response to outputting an unstable status of the short-term voltage stability of the power system.
