The invention discloses an intelligent lock control system for the electric power field and a control method, and belongs to the technical field of electric power field application systems. The intelligent lock control system comprises a main control terminal, a lock control terminal and a mobile terminal, and the lock control terminal and the mobile terminal are both in communication connection with the lock control terminal; the main control terminal is provided with a main control computer; the mobile terminal comprises a RFID label and communication equipment; and the lock control terminalcomprises a power supply module, a control module and an intelligent lock, wherein statistical information is recorded in the control module, the intelligent lock is electrically connected to the control module and is internally provided with a RFID code chip, the RFID code chip reads identification information recorded by the RFID label and sends the identification information to the control module, the control module makes a comparison to judge whether a holder has the unlock permission or not and sends the unlock request to the main control computer when the holder is judged to have the unlock permission, and the main control computer sends dynamic passwords to the communication equipment and the control module at the same time. By adopting a mode of identifying first and then authorizing unlocking to carry out progressive management, the intelligence, the safety and the effectiveness of power security and protection management are improved.
