我国牵头制定的两项高压直流开关设备领域国际标准发布

Core Viewpoint - The recent publication of two international standards for high voltage direct current (HVDC) switchgear, led by China, establishes unified technical specifications for HVDC circuit breakers and converters, enhancing global trade and cooperation in HVDC technology [1] Group 1: International Standards - The two international standards are titled "High Voltage Switchgear and Controlgear Part 313: DC Circuit Breakers" and "High Voltage Switchgear and Controlgear Part 315: DC Disconnectors" [1] - These standards define the technical requirements and testing methods for HVDC circuit breakers and converters, providing a framework for global HVDC switchgear [1] Group 2: Importance of HVDC Technology - HVDC switchgear is a critical component in the construction of new power systems, ensuring safe and stable operation while facilitating large-scale integration of renewable energy and cross-regional transmission [1] - The development of these standards supports the creation of a clean, low-carbon, and efficient energy system [1] Group 3: China's Leadership in HVDC - China has accumulated significant research and engineering experience in the HVDC field through major projects such as the Zhangbei Flexible DC Project and the Baihetan-Jiangsu UHVDC Project [1] - The release of these international standards reinforces China's global leadership in HVDC transmission technology and equipment [1] Group 4: Collaborative Efforts - The standards were developed over five years by a working group led by Chinese experts, including contributions from experts from nine other countries: Germany, the United States, France, Italy, Japan, Norway, and Spain [1]
