精确的控制通过减少网络中的热损失来提高热传递效率，它还使工厂能够在电力和热消耗的快速变化中保持最佳运行状态。Fortum位于埃斯波的Suomenoja热电联产电厂是芬兰第一家使用多变量模型预测控制优化其区域供热网络动态的电厂。这项开发工作建立在2012年Fortum Suomenoja工厂进行的优化工作的基础上。新控制系统计划于2014年投入使用。Espoo、Kauniainen和Kirkkonummi地区的区域供热网络是一个庞大而复杂的网络，包括区域供热和供冷的生产、输送网络、泵站和数千个终端用户。到目前为止，集中供热网络的最佳运行条件一直是由人工维持的，运营商不得不用超过必要的热量来运行网络。“通过新的自动区域供热控制系统，可以有效地控制网络不同部分的区域供热网络的压力和温度。精确的控制通过减少网络中的热损失来提高热传递效率，也使我们能够在电力和热消耗的快速变化中保持最佳运行状态。这两项改进都降低了燃料消耗和二氧化碳排放，使热电联产成为一种更加环保的供暖形式，”富通热电公司生产总监Timo Aaltonen说。“新的先进优化解决方案将通过更好的网络控制，为区域供热商提供经济和环境效益。 Metso has developed a performance solution that is based on customer needs and enables customers to better cope with their challenges now and in the future," says Sami Pitkänen, Vice President, EMEA Services, Automation, Metso. According to Pitkänen, Metso's control solution will benefit energy companies in all countries where district heating is a widely used form of heating, such as Finland, the Baltic countries, Sweden, Germany and Poland. Located in Espoo, the Suomenoja power plant produces heat for the inhabitants of Espoo, Kauniainen, and Kirkkonummi, and electricity for the national grid. The power plant produces approximately 1,800 gigawatt-hours of electricity and 2,200 gigawatt-hours of district heat per year. Based on successful steam network optimization The new district heating network optimization solution is a continuation of Metso's pioneering work on steam network optimization, which has proven to be a success around the world at CHP plants. Core to both solutions are Metso's optimization experts who design, implement and configure the optimization solution based on each customer's requirements, steam network and systems. The solution is built on multivariable model predictive control, which is capable of simultaneously controlling several network variables, predicting primary variables and handling control constraints. At the Suomenoja plant, the optimization package will be integrated into the existing Metso DNA automation system, but it can be integrated into any automation system used at a power plant. "Better control of temperature and pressure fluctuations at the heat plant minimizes heat stress to district heat piping, and thus is one tool to avoid severe disturbances," points out Juha-Pekka Jalkanen, Director, Plant Performance Solutions, Automation, Metso. "Better control of the pressure difference throughout the network also removes the need to produce any additional heat, resulting in higher energy efficiency." Fortum's purpose is to create energy that improves life for present and future generations. The company provides sustainable solutions that fulfill the needs for low emissions, resource efficiency and energy security, and deliver excellent value to its shareholders. The activities cover the generation, distribution and sales of electricity and heat as well as related expert services. Fortum's operations focus on the Nordic countries, Russia, Poland and the Baltics. In the future, the integrating European and fast-growing Asian energy markets provide additional growth opportunities. In 2012, Fortum's sales totaled EUR 6.2 billion and comparable operating profit was EUR 1.7 billion. It employs approximately 10,400 people. The Automation segment's process automation and flow control solutions meet the growing needs of Metso's customer industries to improve production process efficiency as raw materials and energy sources become scarcer and their costs increase.
