Embodiment Construction

[0045] In order to explain the overall concept of the present application more clearly, the following detailed description will be given by way of examples in combination with the accompanying drawings.

[0046] The embodiment of this application discloses a method for automatic inspection of equipment in a power system, such as figure 1 As shown, in step 101, the fault recording device respectively acquires first data to be detected and second data to be detected of one or more devices to be detected.

[0047] The device to be detected transmits the first data to be detected to the fault recording device through the MMS protocol in IEC61850 and the GOOSE export message. Among them, the GOOSE export message is used to transmit switch value information to determine the location of the fault; the MMS protocol is used to transmit protection action event information, alarm information, switch value displacement information and wave recording report information. Wherein, in the em...

Abstract

The invention discloses an automatic regular checking method for equipment in a power system and a fault recording device. The regular checking method includes the steps that the fault recording device respectively acquires first to-be-detected data and second to-be-detected data of one or more to-be-detected equipment, wherein one to-be-detected equipment corresponds to one first to-be-detected datum and one second to-be-detected datum; a data transmission carrier of the first to-be-detected data is different from a data transmission carrier of the second to-be-detected data; according to thefirst to-be-detected data and the second to-be-detected data, the fault recording device determines running state information of the corresponding to-be-detected equipment, and the running state information is stored; and when the fault recording device determines that the current time node is a regular checking time node, the fault recording device obtains detection result of the corresponding to-be-detected equipment according to the stored running state information. The automatic regular checking method can improve the regular checking efficiency.

Description

technical field [0001] The present application relates to the field of power systems, and in particular to an automatic equipment inspection method and a fault recording device in a power system. Background technique [0002] In the power system, it is necessary to carry out regular inspections on the protection devices in the power system, that is, the regular inspection of the protection devices. In the regular inspection of protection devices, standardizing the planned inspection and maintenance of each equipment can make the management of the equipment in a controllable and in-control state, reduce the failure rate of the equipment, improve the health level of the equipment, and ensure the safety and economy of the unit equipment. , Reliable operation. Therefore, regular inspection of power grid protection devices is an important guarantee for maintaining the safe and stable operation of the power grid. [0003] At present, most of the regular inspections of power supp...
