Description

A method for regular inspection of relay protection

technical field

The invention relates to a relay protection fixed inspection method, which belongs to the field of electric power.

Background technique

The relay protection devices in the power system are set in the protection cells, and most of them use decentralized protection cells. The information of the relay protection devices in the protection cells is sent to the server in the monitoring room through the network. Therefore, the relay protection technicians When the relay protection device is regularly inspected in the protection cell, the situation of the messages and optical characters of the monitoring system in the monitoring room cannot be known on the spot. Then, when an abnormal situation occurs, the relay protection technicians who perform the routine inspection work cannot Quickly know the fault point of the protection cell, and because there are no accidents and alarm sounds in the protection cell, it is impossible to know immediately whether there is an abnormal fault in the protection cell, and we can only wait for the operator to notify, because the protection cell and the monitoring room The distance is generally relatively far, and it takes a long time to wait for the notification, which is not conducive to the rapid handling of abnormal situations. Since the use of communication equipment is prohibited in the protection cell, the technicians of relay protection need the cooperation of multiple people in the protection of regular inspection and transmission.

Contents of the invention

The object of the present invention is to provide a relay protection fixed inspection method to solve the problem that the existing relay protection fixed inspection system cannot quickly obtain the fault conditions existing in the protection cell.

A relay protection inspection method according to the present invention, the relay protection system involved in the method includes a monitoring room, m protection cells and an intelligent mobile terminal, and the monitoring room, m protection cells and the intelligent mobile terminal are respectively connected to the industrial On the Ethernet bus; the relay protection inspection method is:

The multiple servers set in the monitoring room receive the detection information output by each relay protection device in the m protection cells, generate the detection information output by the relay protection device into the fault message of the relay protection device, and store it,

In the protection cell to be detected, the intelligent mobile terminal is connected to the industrial Ethernet bus, and the intelligent mobile terminal reads the fault reports of all relay protection devices in the protection cell to be detected stored in the server through the industrial Ethernet. Then judge the fault condition of the relay protection device in the protection chamber to be detected, and complete the relay protection fixed inspection of the protection chamber to be detected,

m is a natural number greater than or equal to 1.

The advantage of the present invention is that the technicians of relay protection can easily understand the important information such as the accident message, SOE, switch action, optical word, etc. of the monitoring system when the protection operates, and Cooperating personnel are reduced. More importantly, when an abnormal situation occurs, the accident and alarm sound of the auxiliary system for protection and inspection can effectively remind the relay protection technicians to stop working immediately and find out the cause of the abnormality.

Detailed ways

Specific Embodiment 1: The present embodiment will be described below in conjunction with FIG. 1. A relay protection inspection method described in this embodiment, the relay protection system involved in the method includes a monitoring room 1, m protection cells 2 and an intelligent mobile terminal 3. The monitoring room 1, the m protection cells 2 and the intelligent mobile terminal 3 are respectively connected to the industrial Ethernet bus; it is characterized in that the relay protection inspection method is as follows:

The multiple servers 1-1 set in the monitoring room 1 receive the detection information output by each relay protection device 2-1 in the m protection cells 2, and generate the detection information output by the relay protection device 2-1 into the relay protection device 2-1 fault message, and store,

In the protection cell 2 to be detected, the intelligent mobile terminal 3 is hooked on the industrial Ethernet bus, and the intelligent mobile terminal 3 reads all the information in the protection cell 2 to be detected stored in the server 1-1 through the industrial Ethernet. The fault message of the relay protection device 2-1, and then judge the fault condition of the relay protection device 2-1 in the protection chamber 2 to be detected, and complete the relay protection regular inspection of the protection chamber 2 to be detected,

m is a natural number greater than or equal to 1.

When the relay protection personnel go to a certain protection chamber 2 to carry out regular inspection on the relay protection device 2-1 installed therein, the intelligent mobile terminal 3 is connected to the industrial Ethernet bus, so that the monitoring can be received on site. The fault message in the server 1-1 in room 1 has the same effect as receiving the fault message by using the operator workstation 1-2 in the monitoring room 1. In this way, the fault information in the protection cell 2 can be obtained quickly, which is convenient for rapid Troubleshooting facilitates production, and does not require the cooperation of multiple people, saving manpower and time.

The intelligent mobile terminal 3 is a relay protection auxiliary system, and it is convenient and quick to carry out regular inspection of relay protection, saves manpower and material resources, can quickly obtain fault information, handle faults in the first time, and ensure normal production.

Embodiment 2: In this embodiment, Embodiment 1 is further described. The smart mobile terminal 3 is realized by using a notebook, a tablet computer or a smart phone.

Some of the current smart phones use the Windows system, which can replace the notebook or tablet computer to realize the function of reading fault messages.
