HVDC System Design - Insulation Coordination

职位描述

1. You will perform comprehensive insulation coordination studies for HVDC systems, including AC and DC overhead lines, cables, converter stations, and associated equipment also develop and implement strategies for optimizing insulation levels, considering various overvoltage phenomena such as lightning, switching, and temporary over voltages.

2. You will utilize specialized software tools (e.g., PSCAD/EMTDC, EMTP-RV, ATP-EMTP) for transient analysis and surge arrester selection and positioning also collaborate with other engineering disciplines (e.g., power systems, mechanical, civil) to ensure a holistic and integrated system design.

3. You will define technical specifications for HVDC equipment related to insulation withstand capabilities and participate in design reviews, factory acceptance tests (FAT), and site acceptance tests (SAT) to verify insulation performance.

4. You will contribute to the development of internal standards, guidelines, and best practices for insulation coordination in HVDC applications and conduct technical investigations into insulation-related issues and propose effective solutions.

5. You will stay abreast of the latest industry standards, research, and technological advancements in HVDC insulation coordination and prepare detailed technical reports, presentations, and documentation for internal and external stakeholders.

6. You will be responsible to ensure compliance with applicable external and internal regulations, procedures, and guidelines.

7. Living Hitachi Energy’s core values of safety and integrity, which means taking responsibility for your own actions while caring for your colleagues and the business.
