Example Embodiment

[0029] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0030] The basic idea of ​​the present invention is to carry out logical analysis and judgment on the data information fed back by the ring-closing circuit breaker and the data information fed back by the de-looping circuit breaker, so as to adjust the operation mode of the power grid in a short time and complete Transfer load operation, and can analyze the current command issued during the transfer load adjustment process, whether it conforms to the current grid operation status, and can make corresponding remedial measures for the failure of the grid when the transfer load adjustment occurs, and can be in After the operation, monitor the operating circuit breaker to ensure that the time interval for closing and unblocking the main operating circuit breaker group is within a contr...

Abstract

The invention relates to the technical field of power, in particular to a control method for intelligent loop opening and closing operation. The method comprises the following steps: receiving a loadpower-supply transfer dispatching instruction to select a preset mode of load power-supply transfer, selecting a system mode of load power-supply transfer according to acquired data information, and issuing a loop closing instruction of a loop closing circuit breaker through a switching value output logic unit when the received preset mode is consistent with the selected system mode; performing logic analysis and judgment on the data information fed back by the loop closing circuit breaker to confirm whether the loop closing operation is successfully completed or not; if the loop closing operation is successfully completed, issuing a loop opening instruction of the loop opening circuit breaker through a switching value output logic unit; and performing logic analysis and judgment on the data information fed back by the loop opening circuit breaker to confirm whether the loop opening operation is successfully completed or not; and if the loop opening operation is successful, completingload power-supply transfer operation. Loop closing and loop opening actions of the circuit breaker are quickly completed through logic judgment, and the problem of power failure during operation modeadjustment is prevented.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a control method for intelligent unclosing loop operation. Background technique [0002] At the current stage, all kinds of substations, switching stations, ring substations, and distribution stations, according to the adjustment of the operation mode of the substations, switching stations, ring substations, and distribution stations from the main power supply line to the backup power supply line, have been The power outage method is adopted, that is, the main power supply line is cut off, and then the backup power supply line is connected to complete the transfer, which seriously affects the quality of power supply to users, resulting in power outages for users. [0003] With the construction of the higher-level voltage grid, the lower-level voltage grid should gradually realize partition operation, and the adjacent partitions should maintain mutual backup. The transfer...
