Method for preventing misinformation of signals of switch device of transformer substation in power dispatching system

Abstract

The invention relates to a method for preventing the misinformation of the signals of a switch device of a transformer substation in a power dispatching system, and the method solves the technical problems in the prior art that the switch device in the transformer substation always misinforms or omits in informing so that serious accidents occur, and unnecessary casualties or economic losses are caused; the following technical scheme is adopted: the method is realized based on that a monitoring circuit on a transformer substation end acquires the switch state signals of the switch device and uploads the switch state signals to a registered of a remote dispatch center to be stored; an image acquisition device for acquiring the state image information of the switch is added on the transformer substation end; and a controller with image identification management software, a special memory for storing video images and a middle memory are added in the remote dispatch center. Because the image acquisition equipment is added on the transformer substation end, the state images of the switch device are monitored in real time, detection results and the monitoring results of the monitoring circuit are compared, and the monitoring effect is enhanced.

Description

technical field [0001] The invention relates to a method for preventing false alarms of switchgear signals of substations in a power dispatching system, belonging to the fields of electric power, petroleum, coal, water conservancy, railways, etc., and is used for dispatching centers to monitor the status of circuit breakers or switchgears of sub-substations, especially It is a double-judgment-based method to prevent false alarms of switchgear signals in substations in power dispatching systems. Background technique [0002] In the fields of electric power, petroleum, coal, water conservancy, railway, etc., the dispatching center is the center of each substation, which is used to control and manage each substation, and the power supply system of each substation needs to set up substations, and the substations are located in every corner. Its communication with the dispatch center is based on network and power line transmission. The switchgear in the substation—especially the...

Problems solved by technology

However, due to the influence of various interference signals, when using this method to monitor the switchgear, there will often be false alarms or false alarms, and serious accidents will occur in severe cases. The safest monitoring method is to observe the switchgear in real time with the naked eye. status, but this method is not feasible. If personnel duties are set up in each substation, it will not only waste human resources, but also bring a certain amount of mental and physical pressure to the staff.

Therefore, it is necessary to improve the monitoring method of the switchgear in the substation in the prior art to avoid serious accidents, causing unnecessary casualties or economic losses
