Summary
When constructing a multi-terminal HVDC (MT-HVDC) system with multiple vendors, it is essential to develop technologies that ensure multivendor interoperability. To establish these technologies, a four-year project in Japan titled “Research and Development of a Multi-purpose and Multi-terminal High Voltage Direct Current Transmission System” was undertaken under the leadership of a national research and development corporation starting in 2020. As part of this project, guidelines for control and protection schemes of multivendor MT-HVDC systems were developed, and verification was conducted using Controller Hardware-In-the-Loop

As an example of the main contents of the guidelines, the sequences defined among participants (the power utility and vendors) for MT-HVDC system operation, the input/output signals and their formats between devices, and the agreements on shared result waveforms are described. Next, the target system and the construction of the simulation environment for the multivendor MT-HVDC HIL simulations are explained. This section also addresses the framework for exchanging simulation models and result waveforms. Finally, HIL simulation results are reported. The tests confirmed that each device operated appropriately within the scope of the guidelines. Representative cases include a sudden change in wind farm (WF) output and a DC line fault test. Furthermore, specific results unique to multivendor simulations observed during the tests and the corresponding countermeasures are described.
