PCS-9550 LCC-HVDC Control and Protection System
A conventional HVDC control and protection system is a key part in guaranteeing the overall performance of the HVDC thyristor-based transmission system. It contributes to safe and steady system operation, provides flexible operating modes and accurate control effects, helps to clear fault and assists in system recovery during system disturbances.
A well-designed control and protection system can maximally exert the advantages of HVDC transmission technology in the following aspects:
- Long distance bulk power transmission
- Underground or underwater cables transmission
- Asynchronous interconnection of AC system
The PCS-9550 control and protection system is designed based on very powerful and flexible building blocks built with a stateof- art UAPC platform and connected by high performance fiber optic communication links. It brings the biggest convenience to new and retrofit HVDC transmission projects.
The design criterion for the control system is to reach 100% reliability for the transmission system. The NR Electric's HVDC control and protection system is equipped with parallel redundancy at all levels. All system parts that are involved in the power transfer of the HVDC link are made redundant.
