Blog Highlights

• Application: Fuji Electric’s Kobe site uses the Typhoon HIL platform for their Uninterruptible Power Supply (UPS) development.
• Challenge: To overcome the typical limitations of open-loop and offline simulations in the early product testing stage, as well as the limitations of the high-power tests in the late product testing stage.
• Solution: The adoption of controller Hardware-in-the-Loop (C-HIL) made it easy to develop and debug new control software functionality, as well as verify the operation in cases that are difficult to reproduce in a high-power lab.
• Result: Typhoon HIL reduced the time and cost of UPS control development and increased test coverage.
• HIL Tested means quick reliable results with lower costs and higher flexibility.

Blog Highlights

• Application: The e-mesh Control is designed for the seamless integration of renewables with traditional energy assets.
• Challenge: Ensuring that multiple e-mesh controls communicate in a coordinated way.
• Solution: Typhoon controller Hardware-in-the-Loop used to design and test e-mesh controls
• Result: Typhoon HIL accelerated e-mesh control development time and increased test coverage.
• HIL Tested means flexibility, reliability, optimized, and great performance.

Blog Highlights

• Hitachi Energy need to integrate various DERs and control multiple loads in a complex system environment.

• Before HIL, Software in the Loop was used to develop control algorithms but a system using real controllers was needed to ensure the system works.
• Controller Hardware-in-the-Loop (C-HIL) gives grid flexibility and adaptability to cover many test cases at an appropriate fidelity.
• C-HIL can be used from the early design phase all the way into operational performance and customer demonstration with factory acceptance testing.
• For microgrids with BESS and solar PV, the seamless transition from grid-connected to islanded mode was demonstrated using C-HIL.
• “HIL Tested” for Hitachi Energy means great performance.
  
  

Highlights

• Typhoon HIL solutions enable Hitachi Energy to push the limits of testing product functionality to cover customer needs throughout the entire product lifecycle.

• Software in the Loop (SIL) supports the development of individual algorithms but a higher fidelity testing environment is needed to ensure the system works as a whole.

• Controller Hardware-in-the-Loop (C-HIL) is a combination of real hardware controllers interfaced with a real-time simulation of the power system.

• Standard models in the Typhoon HIL microgrid library helped save 4-5 months in controller development and testing.

• C-HIL technology increased test coverage in a low-cost environment which ensures great product performance and cost-savings for Hitachi Energy customers.

Highlights

• Decentralization, Decarbonization, and Digitalization are driving emerging technologies for distributed control of microgrid assets.
• Hitachi Energy e-mesh is a vertically integrated system that manages and optimizes distributed energy resources from the device level to the systems control and IoT domain.
• Microgrid control systems optimize the flow of different assets to ensure the supply of electricity is stable and reliable.
• A football arena in Norway uses Hitachi Energy e-mesh solutions to integrate renewables in the urban community with microgrids and energy storage capabilities.
• Communication plays a key role in a distributed controls approach in which a high number of signals are transmitted and received between devices.

Blog Highlights

• AVL List GmbH uses Typhoon HIL test solutions in the agile development, prototyping, testing, and maintenance of firmware and hardware versions of their e-Storage BTE product portfolio.

• AVL e-Storage BTE can act as a battery tester and battery emulator for testing and validating batteries, e-motors, and inverters in early development phases.

• Controller Hardware-in-the-Loop (C-HIL) reduces firmware development and testing time, and as a result, speeds up the time-to market-for new features by enabling automated testing through all product variant cases.

• HIL in one word: Agile.
