Mitsubishi Heavy Industries Takasago Technical Institute - Monitoring and Control System for Sodium Test Facility

Overview

The system achieves improved testing and operational efficiency as an equipment control system performing the monitoring and operation for a sodium test facility.

In addition, when system modifications are required for facility operational purposes, the customer can make system modifications on its own, facilitating flexible changes to testing policies and operation.

Background to Introduction and Challenges Faced

As part of improvements to a large-scale test facility carried out to enhance the development of nuclear power-related equipment, the customer required a reliable and sophisticated control system, and after evaluating DIASYS Netmation, which is designed for power plants, adopted the system.

Effects of Introduction

While the facility is difficult to start-up and shutdown and is designed for continual operation, during test operation following equipment upgrades, we managed to adjust various parameters and easily modify the control logic, allowing the facility to resume operation on schedule. The upgraded control system also resulted in space savings in the monitoring room.

Monitoring and Operational Features

Batch Monitoring

On-site testing equipment and utility facilities are collectively operated and monitored.

The operational status and control status of testing equipment is displayed in real-time based on signals read from each piece of equipment, allowing testing to proceed smoothly.

Alarm Display

When an equipment malfunction occurs, a real-time alarm is displayed on the monitoring screen, supporting early discovery of abnormalities. A per-device history of alarm triggering and restoration can also be displayed.

Trend Display

Product manufacturing status, equipment operational status and fault signals can be managed through a trend display.

Real-time trends covering periods of up to 24 hours and historical trends for up to 30 days are displayed.

Management Support Features

Forms

With daily, weekly, monthly and annual reports, forms are managed in the format best suited to the customer.

A file containing a list of warning items generated on a monthly basis can also be created.
