Abstract

The invention discloses a monitoring method and a dispatching monitoring system for substation equipment. The monitoring method comprises the steps of blocking alarm signals sent by abnormal substation equipment when a blocking instruction for the abnormal substation equipment is received, starting timing to obtain a first timing value, and automatically releasing blocking the alarm signals sent by the abnormal substation equipment when the first timing value reaches a first preset threshold value. According to the monitoring method and the scheduling monitoring system for the substation equipment, disclosed by the embodiment of the invention, the blocking of the alarm signal sent by the abnormal substation equipment is automatically released when the first timing value reaches the first preset threshold value, so that the problem of risk caused by the failure of timely unlocking the alarm signal after the abnormal elimination of the substation equipment is solved, and the monitoring efficiency of the scheduling monitoring end is improved, and meanwhile, the monitoring omission risk is reduced.

Description

Monitoring method and scheduling monitoring system for substation equipment Technical Field The invention relates to the technical field of power grid equipment monitoring, in particular to a monitoring method and a dispatching monitoring system for substation equipment. Background In the current technical field of power grid equipment monitoring, a signal centralized monitoring mode is widely adopted. When the dispatching monitoring end monitors the alarm signal, a dispatcher informs the substation personnel to check and process the substation equipment, and the substation personnel eliminates the abnormality of the substation equipment so as to enable the alarm signal to be recovered to be normal and eliminate the alarm signal. However, in some cases, the abnormal elimination of the transformer substation equipment needs to be processed in combination with a working plan, and there is a situation that the abnormal situation cannot be eliminated temporarily, at this time, the alarm signal cannot be recovered to be normal, and the alarm signal may frequently appear, eliminate and appear, so as to affect the monitoring of other transformer substation equipment by the dispatcher, at this time, the dispatcher can block the alarm signal, so that the alarm signal is not displayed any more, and the monitoring authority of the abnormal transformer substation equipment is handed over to the transformer substation personnel, so that the transformer substation personnel takes certain risk control measures for the abnormal transformer substation equipment according to the regulations, such as regular maintenance or inspection of the transformer substation equipment, so as to control the risk. However, there may be a case that the substation personnel eliminates the abnormality of the substation equipment, forgets to notify the dispatcher to release the alarm signal blocking so as to resume the monitoring of the abnormality of the substation equipment by the dispatching monitoring end, and the substation equipment is on site because the substation personnel eliminates the abnormality, does not take the risk control measures such as inspection and the like, so that when the abnormality occurs again in the substation equipment, neither the dispatching monitoring end nor the substation personnel knows nor takes the risk control measures, so that the abnormality of the substation equipment is deteriorated, and serious influence is caused.
