Metso DNA Plant Operation Monitoring

Introduction

Efficiency is a vital element in reducing production costs and maintaining competitiveness in the energy markets. Power plants can no longer afford to operate without knowing the exact status of production, consumption and plant efficiency at all times and making changes and adjustments on time. Neither can they afford to waste time and resources to inefficient data gathering and reporting routines.

Metso DNA Plant Operation Monitoring - a Metso DNA Plant Management application* - provides the power plant personnel with automatic production and consumption reports thus releasing the resources from data gathering to decision making. The DNA Plant Operation Monitoring application also brings the real-time status of production and plant efficiency available on every computer at the power plant, which is the cornerstone for profitable production and performance improvements.

The user interface of the application consists of customized display(s) and report(s) containing the measured and/or calculated data. All calculations are based on existing instrumentation.

DNA Plant Operation Monitoring is a standardized application that can be used for different types of power plants, such as fluidized bed combustion plants, condensing power plants, combined heat and power plants, combined cycle power plants and energy-from-waste plants.

Benefits

The DNA Plant Operation Monitoring application provides the power plant management and operating personnel with a laptop view to the process displaying the relevant production, consumption and performance figures in a compact form, at any time. These figures can be viewed, for example, in regular morning meetings as a basis for planning the tasks for the day. The history data and changes in the figures can be tracked by easy-to-use trending tools.

Automatic reporting of cumulative production and consumption figures, e.g. on a monthly basis, produces data necessary for invoicing, purchasing and budgeting with minimum effort.

The DNA Plant Operation Monitoring application is linked seamlessly to the overall automation applications, which guarantees efficient collaboration between plant management and plant control.

Features

The user interface of the application is composed of a flexible number of customized reports and displays, which visualize the operation and performance of the power plant and report the cumulative production and consumption data.

The Power Plant Main Display provides a laptop view to the power plant overall balance showing the fuel inputs into the plant and the electricity, process steam and district heat outputs received as a result. The performance indicators, such as power plant total efficiency and power-to-heat ratio are calculated based on these heat inputs and outputs.

The Water/Steam Balance Display displays the steam production of boilers, steam supply and condensate return of consumers, feed water flows and excess water flows. Increase in balance difference indicates faults, for example malfunction of an important measurement that is used for invoicing.

Trends - for selected performance values - can be utilized to provide a quick overview of the performance as well as the direction and magnitude of change.

The Fuel Consumption Report summarizes the fuel consumption [t, MWh] for each fuel and component.

The Power Plant Production Report summarizes the output of the power plant:

Electricity generation, gross/net
Own power consumption
Electricity output for each consumer
Process steam output, total/for each consumer
District heat output

The Management Report contains a compact summary of the most important production figures for “quick-viewing” by power plant management:

Total fuel consumption for each fuel
Total electricity output for each customer
Total process steam output for each customer
Total district heat output for each customer
Total efficiency of the plant
Power-to-heat ratio

*The Metso DNA Plant Management consists of modular applications specifically developed for the energy industry to meet the monitoring, reporting and production optimization needs of power plants.

The Plant management applications are designed to assist in all areas of power plant operation - from management to production and maintenance.
