The Reactor Coolant Pump (RCP) Drive is a critical single-point-of-failure electrical equipment in the third-generation AP1000 nuclear power plant. In 2022, Shandong Nuclear Power Company Ltd., Shanghai Nuclear Engineering Research & Design Institute, and Shanghai Nancal Electric Co., Ltd. initiated a collaboration and successfully developed an RCP Drive for the third-generation AP1000 nuclear power plant in 2023. This significantly enhances the operational reliability of the RCP Drives and the flexibility of standby RCP Drive switching, further improving the operational reliability and economic efficiency of AP1000 nuclear power units.
The aromatic hydrocarbon plant is one of the largest single-train crystallization process facilities in China, with a required annual operation time exceeding 8,000 hours. Nancal Electric's high-capacity water-cooling medium voltage drive stood out due to its superior performance and high-reliability technological advantages. Over two years of operation, the system achieved zero unplanned downtime, meeting all process and reliability requirements for aromatic hydrocarbon production.
In a chemical gasification plant, the propylene compressor plays a crucial role with high demands for operational reliability and stability. Equipment failure can have severe impacts on the plant and downstream production. The plant originally used an imported medium-voltage drive, but its failure rate has been increasing. A significant failure, especially one that cannot be quickly repaired, could halt gasification operations, disrupt downstream production, and lead to substantial economic losses. After extensive research and technical discussions, the user selected Shanghai Nancal’s medium-voltage drive for hot standby, enabling the redundant automatic switching technology of NC HVVF to resolve issues caused by failures in the original imported drive and ensure uninterrupted production.
Storage is an energy infrastructure integrating the functions of seasonal peak regulation, emergency gas supply and national energy strategic reserve. As a key equipment supplier of compressor units, Nancal Electric has excellent on-site service technology and fast response, which has been highly praised by Petrochina Southwest Oil and gas Field Huangcaoxia Gas Storage Construction Project Department and Sichuan Huacheng Supervision Company.
Nancal HVVF series drives can be used in constant torque control such as conveyor. The key control performance is to realize the coordination between multi-motors.
