Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a power plant, a substation,
Alternatively, the present invention relates to a device monitoring / driving support system for devices installed in electric stations such as switchyards.

[0002]

2. Description of the Related Art Generally, a substation is provided with a power switchgear such as a gas-insulated switchgear for turning on and off a high-voltage main circuit, and an oil-filled device such as a transformer and a reactor. Such equipment is required to have improved reliability, reduced maintenance, accident prevention, and early response when an accident occurs. Therefore, conventionally, a device monitoring / driving support system for power devices has been proposed for the purpose of satisfying these requirements.

FIG. 9 shows a conventional example of a device monitoring / driving support system. This device monitoring / driving support system uses a plurality of detection means 4 for detecting various physical quantities and chemical quantities related to the state of the equipment.
1, the output of the detecting means 41 is measured by a plurality of measuring means 42, the measurement data is collected by the measurement data collecting device 43, and the measurement data is displayed by the data display device 44. .

More specifically, in the conventional equipment monitoring / driving support system, the measurement data collecting device 43 and the data display device 44 are installed in the main building of the electric station, and the data indicating the abnormality sign of the equipment is measured. In the case where the data is displayed, the data displayed on the data display device 44 is confirmed in the main building of the electric station. Further, when the data indicating the abnormality of the device is measured, the aggregated information of the abnormality occurrence is transmitted to the upper electric station monitoring device 45 by the contact information, and is transmitted to the upper control station distant from the electric station monitoring device 45. You will be notified.

Next, the expected effects of such a device monitoring / driving support system will be described with reference to FIG. Here, FIG. 10 is a potential deterioration failure model diagram in which the vertical axis represents the potential characteristic L of the sample and the horizontal axis represents the elapsed time t. In the process of becoming a phenomenon as an accident, it progresses at an accelerated rate at point f, leading to an accident phenomenon with no time margin, so it is desirable to find an abnormality in the warning area B at points a to e. The reason for this is as follows.

That is, since various abnormalities develop in a physical phenomenon over a long period of time, it takes a considerable time from the warning area B to the point f. Therefore, even if an abnormality is confirmed, if it is in the warning area B, direct emergency processing such as an emergency stop is not necessary, and a repair allowance time due to a spontaneous stop can be obtained. There is no accident expansion phenomenon such as the next damage, and the repair area can be limited to the minimum necessary area.

There are two kinds of data in the measurement data showing the latent characteristic L. That is, it is current value data such as current physical quantity and chemical quantity, and cumulative value data that is a cumulative value of the physical quantity and chemical quantity from the past.

For example, when a gas insulated switchgear at a substation is to be monitored, the measured data corresponding to the current value data is gas pressure, partial discharge charge amount, oil pressure, decomposed gas amount, switch operating time, etc. Yes, the measurement data corresponding to the cumulative value data is the contact wear amount of the switch. When a transformer is to be monitored, the measured data corresponding to the current value data is the oil temperature, load current, operating time of the load tap changer, etc., and the measured data corresponding to the accumulated value data is the load. It is the amount of contact wear of the hour tap changer, allowable high load duration, etc.

[0009]

However, the conventional device monitoring / driving support system as shown in FIG. 9 has the following problems.

First, the measured data can be confirmed by a data display device installed in the main building of the electric station, but only the aggregated information of the occurrence of the abnormality is transmitted to the host control station which controls the operation of the equipment. It was only done. Therefore, when an abnormality of a device at a certain electric station is detected, in order to confirm the detailed information, the maintenance personnel go to the electric station and check the data displayed on the data display device 44 in the electric station main building. Had to do. As a result, the burden on maintenance personnel increases, delays in responding to accidents, and deterioration of equipment operability.
Eventually, the economic efficiency of the entire equipment was deteriorated.

Further, even if an abnormality of an electric station is detected in the host control station and it is necessary to control the equipment corresponding to the abnormality, the equipment of the electric station cannot be controlled in the host control station, and therefore maintenance personnel Had to go to the electric station to control the device. For this reason, the burden on the maintenance staff is increased, the response to the occurrence of an abnormality is delayed, the operability of the equipment is deteriorated, and the economic efficiency of the entire equipment is deteriorated.

An example of an increase in the burden on the maintenance staff caused by the inability to monitor and control the equipment at a remote location will be described below. In general, electric power demand increases in the summer, and transformers and other substation equipment are frequently operated at a high load just below an allowable limit at this time, and sometimes overloaded. Overload operation significantly shortens the life of the equipment and should be avoided in general, but in case of unavoidable overload operation, auxiliary cooling measures such as forced water cooling are necessary. Therefore, when it is not possible to monitor and control the equipment at a remote location, maintenance personnel go to the electric station for patrols, check the monitoring data of the equipment to be monitored, and assist the forced water cooling etc. if necessary. Cooling must be controlled. Such patrol significantly increases the burden on maintenance personnel.

It is an object of the present invention to provide a highly-functional and highly-functional device monitoring / driving support system that can improve and thereby improve the economical efficiency of the entire facility.

A second object of the present invention is to monitor the equipment installed at the user's electric station, generate some useful consulting data from the monitoring data at the time of maintenance and inspection, or when an abnormality occurs, and provide the user with the consulting data. It is to provide a device monitoring method that can be provided.
