Swedish Technical Consulting Company Solvina Chooses Dassault Systèmes Solution

PLM Solution Enables Solvina to Develop Effective Control Strategies for Improved Plant Productivity and Energy Usage

GOTHENBURG, Sweden — January 25, 2011 – Dassault Systèmes (DS) (Euronext Paris: #13065, DSY.PA), a world leader in 3D and Product Lifecycle Management (PLM) solutions, announced today that the Swedish technical consulting company Solvina has chosen its Dymola modeling and simulation solution to optimize the development of effective control strategies for plant productivity and energy consumption.

Poorly configured control systems can lead to excessive energy consumption and production inefficiency. Therefore, many of Solvina’s customers are in great need of energy optimization. One example is the pulp and paper industry where optimized steam net control enables maximized energy production and minimized oil heating, without dumping of steam and with a stabilized pressure level to all steam consumers.

In order to manage these challenges, Solvina leverages the Dymola modeling and simulation solution by Dassault Systèmes to define the optimal control strategy and configuration, then improving production and energy usage at the plant. The solution is also used to evaluate and adapt control solutions by simulation before implementation.

“A project for a Swedish pulp mill resulted in power savings of 20 MWh/day, which implies cost savings of approximately 500,000 Euros per year,” said Veronica Olesen, project and systems engineer at Solvina. “Without Dymola, we simply could not do our job. It’s the best way to help plant operators achieve enhanced performance and plant availability. If the controller works in the virtual world, it will work in the physical plant.”

Dymola makes it possible to simulate dynamic and complex interactions between, for example, mechanical, electrical, thermodynamic, hydraulic and control systems. This means users can create more integrated models, thereby obtaining simulation results closer to reality.

“The advantage with Dymola is its top-down approach, which enables us to represent the plant with few components and from this model we can test different control strategies much faster than if we had to include all the plant details in our model from the beginning,” said Olesen.

Dymola is based on the modeling language Modelica, allowing users to create their own library of models, or modify existing models, so that they will match users’ unique modeling and simulation needs to a higher degree.

Among Solvina’s customers are large companies such as ABB, AkzoNobel, Banverket, Fortum, Holmen Paper, SCA, Vattenfall and Volvo.
