Control Systems Electric Power Monitoring Systems

Overview

The electric power monitoring systems offered by DIASYS Netmation provide monitoring and control of electric power equipment including the power receiving and transforming facilities installed in buildings, plants and in the transportation sector.

Moreover, by utilizing the electric power demand monitoring function and energy visualization function, power consumption can be managed to conserve energy.

Features

Extensive Range of Monitoring and Control Features

A wide range of monitoring and control features such as start-stop control, power interruption and restoration features and the electric power demand monitoring function are included, aiding customers in the optimum operation of their equipment.

Early Detection of Equipment Abnormalities

Through an alarm notification function when an equipment abnormality is detected and a graphical screen configuration for identifying the location of a fault at a glance, we make it possible to deal with equipment abnormalities quickly.

Monitoring and Operational Features

Group Start-stop Control

Equipment subject to start-stop control can be operated on the basis of pre-registered groups.

Electric Power Demand

To prevent power consumption from exceeding contracted power, power consumption is measured according to a set cycle, producing an alarm when power consumption is predicted to exceed contracted power.

In addition, warning level notifications are issued as part of the demand control (peak cut control) feature. The amount of power to be adjusted as notified from the demand monitoring is used to derive the cut-off level, allowing pre-registered devices to be controlled in order to avoid the excess power consumption.

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.

Alarm Notification

Through an alarm notification feature that works over the Internet or PHS communications, even when an operator is away from the site, they can quickly take action to address an equipment fault.

Trend Display

Information such as trend data, the number of device start-ups and stops and operating times is collected and saved. The saved data can be displayed as a trend screen, and also converted into a CSV file for output.

Management Support Features

Form Features

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.

Optional Features

Energy Visualization Function

With a wide range of monitoring and analysis features including basic unit calculations and energy consumption, CO2 conversion and a comparison of equipment operating statuses with the use of Gantt charts, efficient plant operation and reduced energy consumption is achieved.

Remote Monitoring Function

The Internet-based remote monitoring function allows production status to be verified from a different building inside the plant.

MHPS has also developed a communications protocol designed for remote monitoring. Using this protocol, screens can be displayed at the same speed as an on-site Operator Station (OPS), even over an analog telephone line.
