On January 6, 2019, the 1st and 4th meeting of the Technical Committee for Standardization of DC Distribution System of China Electric Power Enterprise Federation and the Standard Review Conference were held in Beijing. Seventy-five members of the Bidding Committee and their representatives, consultants and representatives of seven standard drafting units such as "General Technical Requirements for 10kV DC Circuit Breakers" from 42 units such as industry associations, scientific research institutes, universities and production enterprises participated in the meeting. Director Xiang Fanghuai of the Standard Innovation Management Department of the State Administration of Market Supervision and Administration, Director Liu Yongdong of the Standardization Management Center of the China Electric Power Enterprise Federation, Chairman of the Bidding Committee and Director Sheng Wanxing of the Distribution Institute of the Chinese Academy of Electric Power Sciences attended the meeting. The meeting was chaired by Wu Ming, Secretary-General of the Bidding Committee.

Leaders attending the meeting

Director Xiang Fanghuai of the Standard Innovation Management Department of the State Administration of Market Supervision and Administration delivered an important speech, pointing out that group standards should be "systematic, high-quality, rapid and internationalized", and expressing the expectations of the State Administration of Market Supervision and Administration for China Telecom Union and the Bidding Committee.

Director Liu Yongdong of the Standardization Management Center of China Electric Power Enterprise Federation fully affirmed the work done by the Bidding Committee in the field of DC distribution standardization since its establishment. He put forward eight-character requirements for the Bidding Committee to be "scientific, open, standardized and leading". He also made cooperation between the Bidding Committee and the DC distribution industry, the combination of standard formulation and practical projects, 10kV DC circuit breakers and DC insertion. The next work plan of the key standards, such as seats, etc., provides guidance.

Chairman of Bidding Committee and Director of Sheng Wanxing, Distribution Research Institute, China Academy of Electric Power Sciences, made the first report on the work of Bidding Committee in 2018, and gave the six-character policy of "timely, authoritative and effective" to the steady progress of Bidding Committee's work. Four requirements were put forward: First, Bidding Committee should further promote cooperation among grid system units, universities and enterprises, from top to bottom, from bottom to bottom. To deepen the technical exchanges among enterprises in an all-round way; to complete the standard revision work carefully to ensure the authority of standards; to pay attention to the effectiveness of standards, speed up the construction of standard verification bases and demonstration projects, and focus on industrial development to ensure the applicability of standards; and to strengthen the promotion of internationalization, push the practical experience and achievements of the bid committee over the international market with the help of CIG. RE, IEC and other international standardization platforms continue to enhance China's domestic and international influence in the field of DC distribution.

Wu Ming, Secretary-General of the Bidding Committee, presented to the General Assembly a report on the work of the Secretariat of the Bidding Committee in 2018. He also reported to the General Assembly the revenue and expenditure of the Bidding Committee in 2018 and its budget for expenditure in 2019. This paper introduces the international work trends of the Secretariat such as IEC/CIGRE in 2018. The Bidding Committee fully supports the work of CIGRE SC C6.31 "DC Distribution Technology" Working Group, leads the completion of two special technical reports of "Research on DC Distribution Technology" and "Global Investigation of DC Distribution", organizes an international seminar on DC Distribution, and puts forward the DC Distribution Standard System at the 2018 IEC Conference in Busan, Korea. The above international work has effectively enhanced the leading power and influence of China's international standard-setting in this field. Next, the Secretariat introduced the standard project formulation and the work plan for 2019.

Sixth International Conference

The meeting discussed and adopted three standards: General Technical Requirements for 10kV DC Circuit Breakers, Technical Guidelines for the Formulation of Power Supply Schemes for DC Distribution Systems, and Technical Specifications for Multifunctional Circuit Breakers for Low Voltage Ungrounded DC Systems.

Three criteria are sent to the site of the review meeting

The meeting heard the progress of the compilation of four standards, such as "Design Code for 10 kV and Below DC Converter Stations". Nine new standard proposals, such as the work plan of the Bidding Committee for 2019 and "Technical Code for Planning and Design of Medium and Low Voltage DC Microgrid", were considered.

Representatives for Standard Review and Planned Reporting

Technical exchanges were also conducted on Key Technologies of regional DC distribution networks, circuit breakers for DC distribution systems and DC distribution technologies.

Technical Exchange Representative

This conference is a grand gathering in the field of DC distribution system technical standards, which will lay a good foundation for the industry to carry out standard technology research in new fields and the implementation of standards.

Annual Meeting Site

Next, the Bidding Committee will complete the standard revision work with high quality to help the development of DC distribution industry. At the same time, it creates a platform for technical communication and exchange for power grid companies, DC distribution equipment manufacturers, universities and research institutes.
