FIG. 1 is a diagram showing a configuration of a substation remote monitoring system according to the present invention.
2 is a block diagram showing a configuration of a substation remote monitoring system of the present invention.
3 is a flow chart showing the operation of the substation remote monitoring system of the present invention.

Hereinafter, a substation remote monitoring system of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a diagram showing a configuration of a substation remote monitoring system according to the present invention.

Referring to FIG. 1, a substation remote monitoring system of the present invention includes a plurality of substation units 100, a plurality of measurement units 200, a server unit 300, and a remote repair unit 400.

Each of the plurality of substation apparatuses 100 has a plurality of used parts 110.

The used part 110 is a device that performs independent functions such as a pump and a temperature sensor.

In addition, the plurality of substation apparatuses 100 according to the present invention include a plurality of sub-components 120.

The plurality of auxiliary components 120 may be a pump, a temperature sensor, or the like.

For example, when the used component A is a pump and the used component B is a temperature sensor, the auxiliary component A1 is a pump capable of replacing A, and the auxiliary component B1 is a temperature sensor capable of replacing B.

The measurement unit 200 is installed in each of the plurality of substation facilities 100 and measures a driving result of the used components 110.

For example, the measuring unit 200 may be a sensor for sensing a pump driving state in the case of a pump.

That is, the measuring unit 200 is installed in each substation 100, and measures the driving state of the used part A and the used part B.

The server unit 300 is connected to the measurement units 200 through a communication line L such as a LAN.

The server unit 300 is electrically connected to the measuring unit 200 of each of the plurality of substation units 100 and drives the measured parts 110 of each of the plurality of substation units 100 The result is sent.

The remote repair unit 400 receives the driving result of the used parts 110 measured through the wireless communication method from the server unit 300 and compares the driving result with a predetermined normal driving reference, When the unsteady driving operation is performed, the same used parts as the used parts in which the abnormal driving is generated are selected and driven by the corresponding substation or other substation 100.

More specifically, each of the plurality of substation apparatuses 100 has the same auxiliary components 120 as those of the used components 110.

The used parts 110 and the auxiliary parts 120 are electrically connected to each other by a standard and a function.

Here, the remote repair unit 400 receives the driving result of the used parts 110 from the measuring unit 200 of each of the plurality of substation equipment 100, The abnormality judging unit 410 judges that the used part 110 having an abnormal driving is determined to be an abnormal part by judging whether the abnormal part is in conformity with the abnormal state of the transformer 100, (120) having the same specifications and functions as those of the abnormal parts among the auxiliary parts (120) provided in the corresponding substation facility (100) And a driver 440 for stopping the driving of the abnormal part and driving the selected auxiliary part 120. [

For example, if the used part A of the No. 1 power plant is determined to be an abnormal part, an auxiliary part that can replace the used part A is searched and selected in the one-side power plant.

Then, when the corresponding auxiliary part is found, it is selected as an auxiliary part A that can replace the used part A, the driving of the used part A determined as an abnormal part is stopped, and the auxiliary part A is driven.

Meanwhile, in the case where there is no auxiliary component having the same standard and function as the abnormal component among the auxiliary components included in the corresponding substation installation, , Auxiliary parts having the same specifications and functions as those of the abnormal parts are selected.

That is, when the use part A of the No. 1 power plant is judged to be an abnormal part, an auxiliary part that can replace the used part A is searched and selected in the 1-side power plant.

If there is no auxiliary part capable of replacing the used part A in the first substation, an auxiliary part that can replace the used part A among the second to N-th substation equipments is searched and selected.

Then, when the corresponding auxiliary part is found, it is selected as an auxiliary part A that can replace the used part A, the driving of the used part A determined as an abnormal part is stopped, and the auxiliary part A is driven.

In addition, the remote repair unit 400 includes a controller 450.

The controller 450 temporarily stores the driving information of the used part judged as the abnormal part when the used part in which the abnormal driving is generated by the determiner 410 is determined to be an abnormal part, So as to maintain the virtual driving state for the reference time.

The controller 450 receives and sets the reference time from the server unit 300, and the reference time may be a time until the abnormal part is replaced with a normal used part.

That is, if it is determined that the used component A is abnormal driving in the No. 1 power plant, the drive route until the used component A is judged as abnormal driving is converted into a log file, temporarily stored, And can be controlled to be operated in a virtual manner for a certain period of time.

The reference time may be the past replacement time history information of the used part A judged to be in an abnormal operation, and the standby time may be established without stopping the corresponding substation until replacement with a new part.

The embodiment of the present invention monitors the operation status of the components in a plurality of substation systems in real time and controls the operation of the substation when the component abnormality occurs The same auxiliary components included can be used to enable maintenance without facility shutdown.

Further, each of the plurality of substations 100 may be provided with an auxiliary measuring unit (not shown).

The auxiliary measuring unit senses a signal for stopping the driving of the abnormal part by the driver (440).

The auxiliary measuring unit monitors whether or not the driving of the abnormal part is stopped. If the abnormal part is driven, the power supply line for driving the abnormal part is forcedly shut off before the selected auxiliary part is driven do.

Accordingly, it is possible to prevent the abnormal condition of the equipment, which is caused by a malfunction of the abnormal part in spite of the drive stop signal and driving the auxiliary part at the same time.

Although the embodiments of the remote monitoring system of the present invention have been described above, it is apparent that various modifications may be made without departing from the scope of the present invention.

Therefore, the scope of the present invention should not be limited to the above-described embodiments, but should be determined by the scope of the appended claims and equivalents thereof.

It is to be understood that the foregoing embodiments are illustrative and not restrictive in all respects and that the scope of the present invention is indicated by the appended claims rather than the foregoing description, It is intended that all changes and modifications derived from the equivalent concept be included within the scope of the present invention.
