In large-scale power plants such as nuclear and thermal power plants, thousands of sensors are installed to monitor the performance and health of the plant. However, it is difficult for operators to monitor all sensor values at all times. Therefore, Toshiba has developed a unique AI technology that comprehensively monitors thousands of sensor values and detects possible abnormalities earlier than humans. In a power plant, there are major fluctuations in sensor values during operation and minute fluctuations...

In power plants, a large number of sensors are installed and the measured values are used to control and operate the plants. Although operators monitor the measured values for daily operation and maintenance, the number that can be visually confirmed is limited. So far, we have proposed two-stage autoencoder for anomaly detection. To evaluate its effectiveness, it and simple autoencoder as a comparison method were applied to the operational data of a power plant. As a result, deterioration of a thermometer ...

During operation or regular inspections at power plants, regular patrol inspections are carried out in order to identify abnormalities at the site at an early stage. In the patrol inspection, in addition to recording the confirmation items, the site situation is recorded with images such as photographs and videos. It is a process that consumes the administrator's time because it is necessary to manage photos and videos by collating them with the layout of the building. For the purpose of streamlining these ...

Due to the increase in aging social infrastructures and the shortage of human resources with the declining birthrate and aging society, labor saving in patrol and inspection work is required. The purpose of this work is not only to reduce the load of patrol and inspection but also to provide new services such as digitization of inspection data. We have developed autonomous four-wheel robot and drone as mobile platforms that can patrol on behalf of workers. The robot can take pictures of the target equipment...

An electrical isolation planning system is now under development to improve the efficiency of operating and maintaining nuclear power plant. The system automates electrical isolation planning, and evaluates the influence of the isolation plan. It also equips an algorithm that automatically adds information such as circuit connection and device attribution to the original paper-drawing. A demonstration of automatic isolation planning was conducted that used actual plant drawings. The system successfully repr...
