The invention discloses an intelligent substation remote control system and a data processing method thereof, and the system comprises a remote control terminal which is used for transmitting an operation instruction, an instruction receiving module which is used for receiving the operation instruction from the remote control terminal, and an instruction analysis module which is used for analyzing the operation instruction to determine a corresponding operation parameter, the command generation module is used for generating a substation control command based on the operation parameters, and the control command sending module is used for sending the control command to the intelligent substation and executing corresponding operation; according to the intelligent substation remote control system and the data processing method thereof, accurate synchronization of equipment state information is guaranteed, and the asynchronous phenomenon is avoided, so that the overall operation efficiency and stability of the system are improved, the adaptability and expansion capability of the system are improved, and the requirement for efficient operation of a modern intelligent substation is met.

The invention relates to a motor control technology, and provides a variable-speed pumped storage unit starting method and device and power equipment, a crowbar device is connected into a variable-speed unit rotor, so that a unit works in an asynchronous motor mode, the situation that the unit is out of step due to the fact that acceleration is too fast during back-to-back starting and SFC starting is avoided, and the starting success rate is increased.

This invention provides a claw-type electrochemical fusing separation mechanism, belonging to the technical field of fusing separation mechanisms. The claw-type electrochemical fusing separation mechanism includes: a separation load housing, a base, a pressure plate, claws, a reversing rod, a fuse, a fuse mounting post, a spring, and cathode material. This invention utilizes the relative positions of the separation load housing, claws, and reversing rod to achieve locking and separation of the housing. A spring is installed between the pressure plate and the base; the pressure plate compresses the spring, and the fuse load achieves locking of the separation mechanism. The fuse, cathode material, and seawater form an electrochemical reaction circuit. The fuse melts due to seawater corrosion, and the spring, freed from external force constraint, springs open the pressure plate. The movement of the pressure plate is converted into the contraction of the claws via the reversing rod, achieving fusing separation. This invention solves the problems of insufficient locking reliability, low fusing time control accuracy, and weak adaptability to deep-sea environments in existing claw-type electrochemical fusing separation mechanisms.
