The invention relates to an information security protection method and apparatus, and a computer-readable storage medium. The information security protection method comprises the steps of: allocating a train control and monitoring system to an intranet region, and performing region boundary security protection on the train control and monitoring system; performing communication network security protection on the train control and monitoring system; and performing terminal device security protection on the train control and monitoring system. The invention deeply integrates an application service of a train control and monitoring system, and defence-in-depth is performed on the train control and monitoring system from a plurality of dimensions such as region boundary security, communication network security and terminal device security, such that attacks initiated from an intranet and an extranet of the system can be effectively handled, and thus, the information security protection capability of the train control and monitoring system is improved.

Information security protection method and apparatus

Provided are a method and system for controlling a voltage. The method includes: acquiring a current output voltage of an inverter; calculating a current voltage error of the current output voltage relative to a given output voltage; inputting the current voltage error into a fuzzy controller to determine a target output voltage of the inverter; determining an amplitude adjustment command based on a difference between an amplitude of the target output voltage and an amplitude of the current output voltage; determining a phase adjustment command based on a difference between a phase of the target output voltage and a phase of the current output voltage; and adjusting an amplitude and a phase of an output voltage of the inverter according to the amplitude adjustment command and the phase adjustment command respectively, to maintain the output voltage of the inverter within a preset range.
