Solvina Achieving optimum control with from Dassault Systèmes

Overview

Challenge Expertise for optimized process turbines. “In a pulp mill, steam pressure Solvina needed to develop control must be at a constant level regardless of efficient control strategies for its Solvina is a Swedish technical consulting the consumption at that pressure level. customers’ power plants to maximize output while minimizing energy company and leading supplier of energy At the same time we need to optimize the consumption. system design, system integration and electrical energy output. This is a very control engineering for the power and complex control problem,” said Veronica Solution process industry. Its 38 highly qualified Olesen, Specialist in Automatic Control, Solvina uses Dymola from Dassault engineers in three divisions - process Solvina. Systèmes to model and dynamically engineering, electrical engineering, safety simulate the way a controller should and quality - provide customers in the Model based programming speeds function for optimal plant productivity and energy use. chemical, pulp and paper, power, energy up the modeling process and nuclear power industries with the To tackle this type of challenge, Solvina Benefits know-how and methods needed to achieve uses Dymola, Dassault Systèmes multi- Customers are ensured optimum enhanced performance and availability of a engineering modeling and simulation operation from the start since Solvina power plant. solutions, to define the optimal controller can test its control strategies through strategy and configuration to improve simulation before any physical Energy is optimized with the right plant productivity and energy usage and modifications or installations are made to the plant. control technology to dynamically test, evaluate and adjust Poorly configured control systems can control algorithms through simulation lead to excessive energy consumption and before commissioning. Solvina adopted production inefficiency. At many Solvina Dymola in 1994 because of its object- customers, demand for energy optimization oriented technology based on the is very high, for example, in the pulp and language and its comprehensive library paper industry. Control technology must of components that can be reused in be developed to optimize the system its various projects. Its fast approach to for minimum energy consumption and modeling makes Dymola the ideal solution “Without Dymola, we simply could not maximum energy output from plant steam for all its projects. do our job. It’s the best way to help plant owners achieve enhanced performance and plant availability.”

Veronica Olesen Specialist in Automatic Control Solvina “The advantage with Dymola is its model- the entire energy production unit, test all based approach, which enables us to changes through simulation, and train represent the plant with our pre-built the plant operators on the new control components with few adjustments,” said system. “For this project, the improved Olesen. “From this model, we can test optimized control resulted in power savings different control strategies much faster than of 20 MWh/day and approximately €500k if we had to program all the plant details in annually,” said Olesen. a new model each time. “Simulation with Dymola speeds up testing and we are confident that if the High level competitiveness controller works in the virtual world, it Verification with Dymola is also fast, which Using Dymola, Solvina has developed will work in the physical plant.” is a considerable advantage when testing generic simulators for different types of Veronica Olesen changes to a controller. Because many power plants to demonstrate the benefits for Specialist in Automatic Control Solvina processes are, in reality, slow, Solvina uses process optimization and training. “Having Dymola to virtually speed up and test these a readymade generic simulator speeds up processes faster than if they had to test the process of customizing it for a particular them in real life. “When we change certain plant,” said Olesen. Solvina has simulation control parameters, we need to test the models for most energy and power impact these changes would have on the applications. “One example is our training entire process. Instead of waiting hours simulator platform, SolvSim Power Plant, for the process to finish, we save time by SSPP, which enables training in a realistic, simulating it with Dymola,” said Veronica yet safe, environment and helps prepare Olesen. “This speeds up testing and we operators and other personnel to handle are confident that if the controller works in difficult scenarios.” the virtual world, it will work in the physical plant.” Today, Dymola enables Solvina to address the most complex process control After purchasing new steam turbines, challenges and to provide customers Solvina pulp mill customer Södra Cell with the most efficient solutions. “Without Mörrum asked Solvina to optimize its Dymola, we simply could not do our job. control systems for steam production and It’s the best way to help plant owners consumption, as well as for overall energy achieve enhanced performance and plant production. Solvina used Dymola to model availability,” concluded Olesen.
