Hitachi ABB Power Grids needs to integrate various DERs and control multiple loads in a complex system environment.
Typhoon HIL solutions enable Hitachi ABB Power Grids to push the limits of testing product functionality to cover customer needs throughout entire product lifecycle.
Controller Hardware-in-the-Loop 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 ABB customers.
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.
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.
What is the challenge?
The electric power systems are going through a transition that encompass digitalization, decentralization, and decarbonization. This will lead to more resilient power grids due to higher adoption of digital technologies, renewable power sources, and new battery storage systems. Everyone will benefit from the enhanced control, efficiency, and maintenance capabilities, but it all has to start from smart test-driven design. There is a need for integrated solutions to improve power system performance which will be data-based, so the systems are built with the end specs in mind and thoroughly tested throughout all possible test scenarios in an automated manner.
At the Honda R&D power electronics development department, improving productivity, streamlining development, and shortening delivery time are essential. These are also the key reasons why Hardware-in-the-Loop (HIL) and model-based development (MBD) is attracting attention in control development. Why did Honda R&D Co., Ltd., a long-time user and advocate of HIL technology, choose Typhoon HIL?
We asked the person in charge at the development department.
The case study featured here is a 3 MW doubly fed induction motor (DFIM) drive used for mining applications. The DFIM drive controls were designed, built, and tested by Indrivetec AG, at the request of CSE-Uniserve. Indrivetec AG is a Zurich-based power electronics, drives, and energy storage company and is an early adopter of Hardware-in-the-Loop (HIL) technology with a research lab primarily based on HIL for control design and testing.
The stator of this motor is connected to the medium voltage grid, and the rotor is connected to a liquid resistor of the system integrator CSE-Uniserve and an Indrivetec Insulated-gate bipolar transistor (IGBT) converter. Here, the resistor is used for starting and running at a constant speed, while the converter is used for variable speed operation.
