2.3. Purpose of the Replica Controller
- Dynamic Performance Test (DPT) under large-scale power system: DPT is performed under a sufficiently wide area network to reflect the dynamic characteristics of the power system considering other HVDC and FACTS facilities nearby.
- Preverification: If the controller needs to be modified, improved, or updated during operation stage, such as adding a new function or in/output signal, the adequacy can be verified and de-risk can be achieved using a replica controller, which cannot be achieved with an actual field controller.
- Parameter Tuning: The huge changes in power systems, such as an adjacent network topology or the installation of a new power plant, require adjusting the controller parameters. KEPCO conducts verification and parameter tuning periodically for HVDC and FACTS operations for potential severe events, such as 765 kV line fault and Special Protection Scheme (SPS), by planning winter/summer operation strategies biannually.
- Event Analysis: The replica controller can analyze the root cause of any malfunction or fault due to its detailed internal protection functions. Particularly, KEPCO can simulate not only a single replica controller but also the entire Korean power system, including all HVDC and FACTS manufacturer models with EMT, which facilitates the interaction investigation of the power system and power electronic devices.
- Operator Training: Training to improve the skill level of the field operators can be conducted. Field operators have few opportunities to deal with actual controllers before project completion. Therefore, the replica controller could be a perfect tool for practical training to gain experience in emergency operation, reaction of communication disruption, alarm analysis, and insertion and block.
