Solvina - Power Plant Engineering Consultants

Solvina provides know-how and methods to create enhanced performance and availability in the power industry. We deliver expert services in power system stability studies, process control, energy optimization solutions, island operation, courses and training. We also have knowledge in wind power integration.

Process control systems and instrumentation

Solvina improves existing process control systems and ensures correct process control from the first start-up. Our process control experts can design superior control strategies for efficient and robust control.

Dynamic simulation for plant development

Solvina often uses dynamic simulation throughout the development process. This means thoroughly tested solutions are quickly put into operation. Our solutions increase availability and production, and we always focus on the entire system in order to avoid sub-optimization.

Solvina's solutions:

• Ensure safe and robust plants
• Focus on the entire system to avoid sub-optimization
• Have effective energy usage
• Are quickly put into operation

Island and in-house operation testing and development

During power system disturbances and interrupted power supply, a power plant can continue running if it can transfer to island or in-house operation and its island operation capability is sufficient. However, as conditions can be tough and sensitive, islanding is complicated. Performing a black start can be even tougher.

Solvina has unique experiences and knowledge of island and in-house operation. Our test methodology, using the real-time simulator SolvSim® Power Station, enables safe island and in-house operation testing and development.

Real-time simulator for island operation testing and governor tuning

Solvina offers a unique simulator-based piece of test equipment used for testing island operation performance in a safe way.

SolvSim Power Station is used for testing power turbines' island operation capabilities. The unique test method makes it possible to test island operation capability while the generator is synchronized to the main grid. This is an advantage since the operation of the electric island is not risked during the test. During the test, adjustments can be made to ensure good island operation performance. When island operation capability has been confirmed, the turbine is ready for running the electric island on its own.

For many power plants and industries, island operation can be of great importance in order to avoid power outage or voltage disturbances from the main grid.

Power system analysis

Using modern simulation tools, Solvina performs power system analysis and can achieve an overview and a clear structure of the system. For instance, we calculate correct relay protection settings to ensure selectivity and correct tripping.

Dynamic power systems stability studies, voltage stability studies and transient and steady-state fault analysis

Solvina also provides:

• Dynamic power systems stability studies
• Voltage stability studies
• Transient and steady-state fault analysis
• Measurements, analysis of grid disturbances and power quality services
• EMF measurements and reduction services

Testing and tuning of governors, voltage controllers and power system stabilizers

Solvina has knowledge of specifying requirement, testing, tuning and requirement follow-ups concerning governors, voltage controllers and power system stabilizers. This is particularly important when new turbines and/or controllers are installed, especially in an existing plant. Ensuring fast and stable control in every installation is our main mission.

Wind power integration and stability analysis

Solvina analyzes and handles issues regarding wind power integration in power systems, especially dynamic phenomena such as stability problems. Solvina also successfully develops dynamic models of wind turbines and aggregated models of wind farms.
