Problems solved by technology

[0003] At present, when the multi-interval sequential control operation (such as main transformer and busbar, etc.) is interrupted abnormally, after the monitor reports to the dispatcher, the dispatcher will order to switch to remote control or local operation according to the equipment status, and the operator needs to draw up a new ticket , ticket review, and operation seriously affect operational efficiency

Embodiment Construction

[0028] In order to better explain the present invention and facilitate understanding, the present invention will be described in detail below with reference to the accompanying drawings and through specific embodiments.

[0029] The present invention provides a method for processing abnormal interruption of sequence control. During the execution of sequence control, after the execution of each operation command is completed, it is judged whether the execution of the operation command is abnormally interrupted. The next operation command; if an abnormal interruption occurs, the interrupt re-control is executed. If the operation command is executed again, the next operation command is continued. If the operation command is not completed again, it is determined that the operated device is abnormal. Terminate the sequence control operation, then repair the equipment and confirm that there is no abnormality in the equipment, and then execute the interrupted relay control. In the pr...

Abstract

The invention relates to a method for processing abnormal interruption of sequence control. By deeply analyzing the business logic of sequence control operation ticket, taking safety and speed as the starting point, and on the basis of ensuring safety, a method is proposed that uses the original method after abnormal interruption processing. The sequence control operation ticket continues to execute the sequence control operation method, so as to improve the sequence control execution efficiency and the sequence control completion rate.

Description

technical field [0001] The invention relates to the field of automatic control of electric power systems, and more particularly, to a method for processing abnormal interruption of sequence control. Background technique [0002] The sequence control function is also called programmed operation. According to the pre-specified operation logic and five-proof locking rules, it automatically completes a series of circuit breaker and disconnector operations according to the rules, and finally changes the process of the system operating state, so as to realize the process of electrical equipment from running, Automatic conversion of various states such as hot standby and cold standby. [0003] At present, when the multi-interval sequential control operation (such as main transformer and bus, etc.) is abnormally interrupted, after the supervisor reports to the dispatcher, the dispatcher will re-order the remote control or local operation according to the equipment status, and the op...
