Problems solved by technology

[0004] The power supply network is complicated, and there are a large number of circuit breakers, and some reclosing functions of circuit breakers on different lines need to be enabled, and some need to be disabled.
At present, dispatchers mainly use manual observation and recording on the spot to monitor and manage the switch-in and withdrawal status of the reclosing switch. First, the efficiency is low, and second, errors and omissions are prone to occur, and the overall effect is poor.

Abstract

The invention relates to the technical field of electric power monitoring, and specifically discloses a method for monitoring the throwing and withdrawing status of a reclosing switch, which is suitable for a power supply line with a circuit breaker, and the start and stop of the reclosing function of the circuit breaker is determined by the throwing and withdrawing of the corresponding reclosing switch State determination, which includes: graphing the power supply lines with circuit breakers to obtain a graphical interface; collecting the switching and withdrawing signals of the reclosing switch corresponding to each power supply line; The graphical identification of the device in the graphical interface is displayed differently. The invention provides a method for monitoring the throwing and withdrawing states of reclosing switches, which can realize automatic monitoring of the throwing and withdrawing states of each reclosing switch, improve scheduling efficiency and reduce error and leakage rates.

Description

technical field [0001] The invention relates to the technical field of electric power monitoring, in particular to a method for monitoring the throwing and withdrawing state of a reclosing switch. Background technique [0002] When the overhead line fault is cleared, closing the circuit breaker in a short time is called reclosing; since most overhead line faults are instantaneous or temporary, reclosing is one of the self-recovery power supply methods often used in operation. [0003] Generally, the reclosing function of the circuit breaker is performed by a reclosing control loop. A reclosing switch is provided in the reclosing control loop. When the reclosing switch is switched on, the reclosing control loop is turned on, and the reclosing function of the circuit breaker is activated. When the reclosing switch exits, the reclosing control circuit is open and the reclosing function of the circuit breaker is disabled. Therefore, the reclosing status of the reclosing switch d...
